Fish and other aquatic creatures

The most unpretentious and small aquarium fish with photos


Aquarists know that even the smallest aquarium can be turned into a work of art, if you populate it with the “right” fish and create comfortable conditions for them. There may be many criteria for choosing pets, for example, color and personal tastes, but you need to remember, it is important to consider their compatibility and the rules of settlement.

The size of the aquarium dictates its conditions

Small recognized aquarium less than 50 liters. So, even in a 10 liter miniature pond you can settle the fish. However, it is worth calculating your efforts, the smaller the liters, the more often you need to do the cleaning, monitor the quality of water and aeration. If you plan to keep tropical rocks in a small aquarium, then you will have to maintain the optimum temperature for their maintenance, about 26-27 degrees. In Akavirumah with a volume of less than 10 liters, this is very difficult to do, since the instruments have large scales that will not fit physically there. Ignore these conditions, too, will not work. Without them, the fish for which you gave more than $ 100 will die.

We carefully study the compatibility of species.

Fish for a small aquarium should be selected depending on many factors. For beginners, it is problematic to take them on your own, so contact the professionals who will help determine which fish can be kept together, and which neighborhoods should be avoided.

Factors important at settling:

  • The ability to survive one by one. Some species can only live in packs, so pay attention to this moment in the first place,
  • Water characteristics for species should be approximately the same,
  • Peaceful nature of the inhabitants,
  • The number of individuals depends on the surface area of ​​the water. The larger the meter, the more fish you can start,
  • Compatibility of rocks. Sometimes peace-loving fish separately do not tolerate each other's neighborhood.

It is important to remember that small aquariums are a zone of increased danger for fish. Therefore, the choice of neighbors fully determine the fate of your wards. If you add predatory fish to a small aquarium, they will eat peace-loving neighbors. For the angelfish fit gurus, other fish will not get along with them. You can get one fish, which will be the mistress of your reservoir, or keep a whole flock of miniature fish.

Unbreakable Settlement Canons

Depending on the volume, you can have a different number of individuals. Thus, in the 10 liter can be placed 2-3 fish to 6 centimeters. If you do not follow the rule of displacement for each representative, then you will create an uncomfortable atmosphere, which will worsen the health and appearance of the inhabitants. In addition to the fish in the aquarium will be gravel and plants, which also take up some volume from the declared manufacturer.

Another nuance when settling the fish in the smallest aquarium. Consider the habitat of pets so that they do not interfere with each other.

Fish are divided into those who:

  • Swim near the bottom - bottom,
  • Swim at an average level
  • Swim in the upper layer.

With such a gradation, the inhabitants will be evenly distributed in the aquarium, which will significantly increase its aesthetic properties. Let us turn to specific examples of ideal inhabitants.

Cockerel perfect fish for a small aquarium. Based on the name, you can easily imagine how they look and their character. Small teasers with a stunning multi-colored color will become an ornament. You can meet monochromatic representatives, often come across multi-colored - red with iridescent in different shades and colors look really great. The optimal volume for one individual - 7 - 10 liters. There is a trick in keeping one cock in the aquarium. Place a mirror in the water that will create the illusion of an opponent who will invigorate your pet. It is desirable to have no more than 1 male per 3-4 females per one aquarium. If you decide to launch another "man", then you need to take care of the partition, which will protect them from death as a result of a skirmish. The ideal neighbors are barbs and danios.

Often, it is from them begins acquaintance with the world of aquarium. They are able to survive in any environment. Omnivores have a great color, which you can talk for a long time. Different types of guppies have a different structure and color of the fins, which will make the artificial reservoir incredibly beautiful. Over time, fashion does not pass on them, so whatever residents you may have brought, you will always remain at the height of fashion. Minimal maintenance of comfort in a 10-liter aquarium is enough to produce offspring.

Buying catfish is a very reasonable way to minimize their own efforts in maintaining the aquarium. Since they feed mainly from the soil and stones, they perform the role of cleaners. In addition, they are completely safe neighbors. If you decide to settle soms, then give preference to 5 identical individuals. 2 representatives need at least 10 liters of water, so counting the number of running soms will come from the number of available centimeters.

Interesting video about unpretentious and small aquarium fish

The most unpretentious and small aquarium fish with photos

I think many aquarium fish experts will agree that the first place is given to guppes.

Everyone probably knows these fish ... even those who have never seen aquariums. We can say that these fish are the fish of all children of the former USSR (they were in all Soviet aquariums))). The fish is very beautiful and unpretentious. The tail fin is her beauty. The simplicity of the fish is that it withstands "difficult conditions of detention." I happened to see an aquarium with guppies. without aeration, without filtering, without plants, without proper feeding etc. - horror, terrible dream aquarist. Nevertheless, guppies managed not only to survive in such an aquarium, but even tried to multiply. So to mock the fish of course not worth it. But their endurance and vitality sometimes affects.


2nd place Swordtails

A very famous fish, as a result of persistent selection, a large number of Swordtails of various colors and shapes were bred. Males differ from females by the presence of a “sword” on the lower edge of the caudal fin.

Swordtails are kept in flocks in a densely planted aquarium. The minimum size of the aquarium from 10 liters (but better is more). A good volume of aquarium for a small group of swordtails is 50 liters.

An interesting fact about these fish is that the female swordtail can “at some” moment become a male, i.e. change the floor. This is due to the struggle for the survival of the species.

3rd place Somiki corridors

It should start with the fact that all aquarium catfish - a priori unpretentious. Moreover, they are “orderlies of the aquarium world”: they clean the soil and eat the remnants of life activity. The corridors are selected from all soms, since in addition to the gill, they have intestinal respirationi.e. if aeration stops, they will live for a long time.

The fish are very peaceful, calm. They slowly swim along the bottom in search of food. In an aquarium they are usually kept in flocks. Fish, do not pose any threat to other inhabitants of the aquarium.

4th place Mollies

Molki, like guppies, are viviparous fishes. Unpretentious and tolerant of poor conditions. Nevertheless, they are more capricious than the “troika of winners”.

Fish suitable for beginners and young aquarists. The fishes most difficult to keep from all members of the family are demanding of conditions, they do not tolerate low temperatures, some like “salty” water, like bright light, etc.

You can read more about MOLLINESIA here.

5th place Tetras - Harazinki

All tetras are small, nimble, not capricious fish. However, they will not be able to survive in “Spartan conditions” as guppies. They need aeration and filtration. You can keep them in the aquarium group (from 5 individuals) of at least 35 liters of water.

You can read more about TETRAH here.

6 place Ternetsii

Very famous little fish. Fish energetic, mobile. Fish get along well with other types of fish. Somehow my terntions even lived with small cichlids. Recommended aquarium with a volume of at least 30 liters of water, densely planted with plants. Aeration, filtration - yes!

You can read more about TERNIA here.

7th place Danio (rerio, pink)

Starting from the 5th place TOP, all the fish require unpretentious attention. Tanks are different from them - briskness and speed of movement. They can coexist with many species of fish, even with fish of medium and increased aggression: scalar, goura and even with small cichlids.

8th place Torakatum

One of the famous large catfish of the aquarium world and excellent attendants of the aquarium. Peace lover and unpretentious to the content. They can be kept in a common aquarium with thickets of plants and a large number of shelters. Fish, do not pose any threat to other inhabitants of the aquarium. Compatible with all kinds of fish. The neighbors are not recommended only one hundred percent aggressors and predators.

9th place Gourami

Gourami - are medium sized fish. Entered in this TOP due to gill labyrinth - fish do not need aerationthey breathe atmospheric air. Really peaceful fish, but sometimes aggression. Some individuals taken separately are even very aggressive, as they say, as lucky.You can read more about GURAMs here.

10 place Barbus

Barbusses are schooling, small fish that can stand up for themselves! If you decide to start a barbus, I recommend to allocate for this a separate aquarium, “barbusyatnik.” "Pirate" temper, the ability to stand up for themselves - deserve 10th place. You can read more about BARBUSS here.

Of course, the above TOP is conditional - always remember the words

Antoine Marie Jean-Baptiste Roger de Saint-Exupery

“We are responsible for those who have tamed”

We also recommend you to look at the colorful brochure "Popular types of aquarium fish". This brochure contains all the popular types of fish, with a description of their conditions of maintenance, compatibility, feeding + photos.

Many undemanding fish can easily multiply in aquarium conditions. The only exception is the characteristic, breeding of which is only possible for experienced aquarists. For beginners in breeding recommended all types of viviparous toothed fish. And speckled catfish, antsistrusy can easily spawn in the general aquarium. Also easy to breed danios and barbs. Labyrinths build foam nests, and cichlids bear offspring in the mouth.

However, in order to be sure of the safety and comfort of spawning fish, it is better to provide them with a separate aquarium and find out if they have a predisposition for cannibalism in order to avoid the death of their fry.

Aquarium pets that are easy to maintain do not pose a problem for responsible beginners in the water world. But the lazy owners of the aquarium will have to comply with the conditions necessary for the normal functioning of the fish, such as clean water and timely feeding, as this will depend on their lifespan. Otherwise, even the most unpretentious fish will not be able to stretch for a long time.

How to set the balance in the mini tank?

Taking care of a small aquarium, on the one hand, is easy, and on the other, it will bring trouble. Choose a mini tank rectangular, with straight and smooth walls. It is convenient to clean them with a scraper, to maintain. If the tank is round, then it will be inconvenient to reach its corners, it is difficult to wash. A 10-liter aquarium pollutes faster than a 50-100-liter aquarium. Water changes will have to be done more often, as well as comprehensive cleaning, which is not useful for the biobalance of the aquatic environment and the health of the fish.

The main disadvantage of mini tanks is a small amount of water. It does not fit a lot of fish. There you can settle 1-2 fish, and no more. In a large aquarium, water changes are not strongly felt, in a small one this is a great stress. Any changes in the biological balance: fish death, overfeeding, pollution immediately affect the aquatic environment. The only thing that can be done is to adjust the water parameters in time, feed the fish carefully, clean the bottom.

See how the ground siphon in the nano aquarium.

To care for a small aquarium should be the same as for a large one. Once a week you need to change 10-15% of water, if necessary. So that the fish do not have stress, do not replace the water completely, try to add it in small portions. The ideal aquarium filter for such a tank is a pump with an internal sponge. The sponge cannot be washed out under running water, otherwise all beneficial bacteria participating in the nitrogen cycle will die.

If you choose the smallest reservoir, then it will be almost impossible to install plants and decorations. Some skillfully planted even in 3-liter jars of dwarf plants, but it is inconvenient to care for them. In the 10 liter tank there is the possibility to hold a dwarf anubias, a dwarf arrowhead, an echinodorus “dwarf amazon”, a dwarf cryptocoryne. Plants for a small aquarium are able to control the level of nitrites, nitrates and ammonia, create shelters for fish. Make sure that the tank is in the ground. Choose a treated substrate, clean, without paint. Remember that using a regular scraper to clean aquariums of minimal size is very difficult from the layer of plaque.

Now about feeding. As is known, overfeeding harms not only the health of the fish, but also adversely affects the quality of water. All uneaten decays, turning into harmful impurities and bacteria. Decay products are deposited on the bottom and reservoir machines, disturbing the stability of the biological environment. Fish should be fed, hunger is also not an option. Once a week, arrange fasting days for the fish. Add food to 4-6 grains, which pet is swallowed by force. What is not eaten, you need to remove the gauze net.

Let's for fish that live in a small 10-20 liter nursery as much feed as they eat in 2-6 minutes. Flakes, live food, sinking granules fit. They sink slowly and do not pollute the environment. If you live bottom catfish, they will eat everything on their own. Fish can be fed to their usual high-grade food, without disturbing the diet. It is important to clean everything in time.

See how to make a small aquarium.

Fish care

Although the majority of small fish are rather unpretentious, leaving for the first time of their life will be troublesome. At first, water will need to be replaced frequently in order to stabilize the number of bacteria. Standard water change should be done every 3-4 days, at the same time at least a quarter of the volume should be updated.

Do not place such an aquarium near the window: the sun's rays will provoke the growth of algae.

A few words about the form. When it comes to a small aquarium, most aquarists clearly state: just not round! Curved walls in a small container strongly distort the image of the fish, and at the same time, a strong distortion of the external environment will also become a stress for the little fish. From a practical point of view, it will be very difficult to clean glasses of this shape.

Choosing fish

There are a few simple rules for choosing small fish in small aquariums. All of them take into account both the peculiarities of the fish themselves and the specifics of the small-capacity tank.

  • Do not purchase predators for a small aquarium, no matter how miniature they are. And in general, turning to the pet store for a choice of fish, be sure to check the size of the adult.
  • No matter how desirable luxury and exclusivity, it is better not to stop your choice on expensive fish. Small aquariums are very unstable in terms of temperature, and fragile, expensive specimens are usually the most sensitive to such fluctuations, for them the slightest change will be fatal.
  • Too many fish are also wrong. There is a classic rule here: there should be at least 3-5 liters of water per fish about 5 centimeters in size.
  • Pick a similar nature of the species. If you move mobile and very calm fish together, there will be no balance in the aquarium. Some of its inhabitants will experience extreme stress. Naturally, it is absolutely not necessary to settle territorial fish in a small aquarium together with other species.
  • The best option for a small aquarium - the neighborhood in the water layers. Some of the fish may belong to benthic species, their neighbors - to enjoy life in the middle layers. With them, you can also inhabit the species that prefers to inhabit the surface.

Unpretentious aquarium fish

Caring for aquarium fish - the whole science. На первый взгляд невозможно запомнить все условия и требования к содержанию, трудно найти средства на приобретение огромного аквариума и дорогого оборудования для него и время на приготовление специальных кормов и регулярное тестирование воды. Но есть рыбки, которые простят новичку его неопытность и возможные ошибки, и уход за которыми не потребует от него огромных материальных и временных ресурсов. Об этих простых в уходе, живучих и неприхотливых обитателях аквариума и пойдет речь.

Viviparous fish

They are considered the most undemanding to the conditions of detention and, in the general opinion, are the best option among aquarium fish for beginners. In turn, among this group there are also champions in vitality. Of course, this is a guppy. These fish are familiar to all, they were popular even in those prehistoric times when the filter, compressor and thermostat in the aquarium were considered a luxury. And the guppies in these aquariums lived, sparkled with their magnificent tails and multiplied.

Small fishes of this species can live in a small amount of water, without filtration and aeration, at different temperatures, exclusively on dry food. Of course, such a life cannot be called a comfortable life, and this may soon manifest itself in a deterioration in the appetite of the fish and the blanching of their colors. Therefore, it is still very desirable to install a filter in the aquarium, carry out water changes regularly (once a week at 20-30%), and try to diversify the food as much as possible.

Another condition for a long and happy life of gops is that there must be a few of them in the aquarium, not less than 5-6 pieces, since they are packaged and feel alone and uncomfortable.

Relatives of guppies, equally popular in novice aquariums, are swordtails. These small bright fish also do not require special care. They are larger than guppies, so they need at least 40-50 liters of an aquarium; about 6 liters of water should be consumed per individual. Otherwise, the fish is also unpretentious, tolerates non-ideal conditions in the aquarium, organic water pollution or high nitrate content in it, and even reproduces in these conditions.

Petilles and mollies are also viviparous fishes, almost as good as guppies and swordtails in their resilience. They need a more constant water temperature. Here, perhaps, all the difference.

The colors and forms of viviparous fish are so bright and diverse that you can create a beautiful, lively and interesting aquarium, using only representatives of these species. And the ease of reproduction at home (the fry are born well-formed, they eat adult food themselves, and for their successful development it is necessary to ensure only the presence of thickets of small-leaved plants, you can even artificial, where they can hide) provides a constant replenishment of the fish population and allows even the beginner Aquarist feel like a true fish farmer.

It should be noted that at present breeders have deduced a large number of different forms of viviparous fish - with unusual colors, veil fins, and so on. These fish are unusually beautiful, but they are much more demanding of conditions of detention and not always suitable for inexperienced owners.

Representatives of carps are the next in the list in popularity among beginners and the ability to survive in difficult conditions.

In this group, first of all, it should be noted danio rerio. This fish, it seems, takes nothing. In my aquarium, my friends once broke the thermostat, in the very heated water all the fish died and only the danios continued to swim as if nothing had happened. These persistent kids even launched into space.

Danios have quite ordinary appearance, but they captivate with their activity and swiftness. The schooling fish, but does not require a lot of space, 8-10 individuals will be perfectly able to live in a twenty-liter aquarium.

It is also quite easy to propagate them - it is enough to put a female (two of three males) that is ready for spawning into a small container, put them near the window early in the morning so that the first rays of the morning sun hit the jar and the fish begin to actively spawn. Growing fry, of course, more difficult than that of viviparous fish, but with due diligence and it is quite possible.

Another frequent inhabitant of small aquariums is the cardinal. It is a medium-sized, up to 4-5 cm long, slender and mobile fish with bright fins. Cardinals are undemanding to the parameters of water, have a peaceful and livable nature, use dry or live food. A flock of nondescript at first glance cardinals will liven up any aquarium.

Barbus are also representatives of carp. In aquariums there are many species of this genus, the most unpretentious of them is considered to be a Sumatran barbus.

He has a bright golden-black striped color, and indeed in the aquarium it is difficult not to notice, his character is too active. Because of this, the bar should not be placed in an aquarium with calm phlegmatic fish, they will be uncomfortable with this jumping bully. Barbs are prone to obesity, so you should not overfeed them. Another possible problem in fish of this species is the stagnation of calf in females. To avoid this, you need to raise the temperature in the aquarium twice a year, stimulating spawning.


Labyrinth fish, perhaps the largest and most elegant of those who can advise a novice for a small aquarium. Macropods reach a length of 9 cm, males - 6 cm (plus luxurious fins of almost the same length), and at the same time they can live in a three-liter jar without aeration, if only there is space between the surface of the water and the lid.

These fish have a special organ - a labyrinth, which allows them to breathe atmospheric air, so they feel good in oxygen-poor water, and other water parameters (temperature, hardness, pollution degree) are not too demanding either.

They have a very good regeneration ability, they can quickly restore damaged fins. Their disadvantage is an aggressive, fighting character: the males are completely intolerant of the males of their own species, and in some cases they can attack other species of fish, especially the macropods. Other labyrinth fish - liliusi, gourami - have a more peaceful disposition (although sometimes gourami, guarding the nest, can survive from a small aquarium of their neighbors), but are somewhat inferior to the macro-feeding and cockerels for unpretentiousness. They, especially breeding forms, require a constant temperature in the aquarium, clean water, the presence of thickets of living plants.


These include such popular species as ternets, neons, various tetras: copper, firefly, rhodostomus. Small, very charming schooling fish with interesting colors, red and golden spots, glowing neon stripes. In ternation, the color is not bright, but its albino form was learned to dye artificially, receiving multi-colored fish called caramel.

These representatives of the Characin are able to live in small aquariums, but they are more demanding in terms of conditions. In particular, they prefer soft, acidic water and do not like massive changes, so the water for the aquarium is better to peat and change regularly, but little by little. In addition, in the aquarium with these fish is very desirable to have live plants.

Because of their amusing appearance and behavior are very popular with beginners. However, they often overlook the fact that rather large catfish grow from the majority of cute little mustaches sold in pet shops. Torakatumov, plexostomus, pterigoplihtov and antsistrusov in an aquarium with a volume of 30-40 liters cannot be categorically kept.

For small aquariums, the unpretentious pygmy corridor (Corydoras pygmaeus) or its close relative dwarf corridor (Corydoras hastatus, catfish) is well suited. They grow only about 3-4 cm, they feel good in a large range of hardness and acidity, do not pay attention to the intensity of light, feed on any dry and live food, if only he was small enough and placed in their mouths. Demanding on temperature only. It should be in the range of 24-26 ° C. Schooling fish, you must keep them in groups of at least 5-6 pieces.

Another small catfish - ototsinklyus. He also does not need large amounts of water for life, but for him the presence of living plants, vegetable top dressing and pure water with a low content of nitrates are necessary.

All these catfish are peaceful and can get along with any fish that will not offend them.

If a novice aquarist is at once serious and ready to spend time on caring for an aquarium and studying special literature, you can recommend him to buy the most simple cichlids - the angelfish and black-striped chichlases. These species need a sufficiently large amount of water (at least 100 liters per pair) and careful selection of neighbors, but otherwise they are not too demanding.

In conclusion, it is worth noting that there are no aquariums and fish that do not require care at all. Fish, like frogs, turtles, tritons are living creatures, and care about them should be constant. If you don’t want to mess with the aquarium, and you just want beauty and a pleasant murmur, it’s better not to torture animals and not to suffer yourself, but to buy a bubble panel and admire its pacifying gurgle.

In addition, it is not enough just to pick up unpretentious fish, it is necessary to consider the following:

  • fish must be compatible, since if, for example, simple guppies and barbs are placed in one aquarium, nothing good will come of it,
  • it is preferable to place related species or species that live in aquarium under similar conditions into one aquarium,
  • when choosing fish, it is necessary to consider what maximum size they can achieve, and based on this, determine the capacity of your aquarium,
  • most small fish are schooling, they need to be acquired immediately by the group.

Only by observing these conditions, you can make your first aquarium a source of beauty and pleasure.

Tip 1: The most unpretentious aquarium fish

Increasingly began to see in a dream a golden fish? So you need to think about purchasing an aquarium. The most important thing in this business is to choose its future guests correctly. Out of love for Pushkin's fairy tales, you can, of course, buy a goldfish, but in the absence of skills on the aquarium side, it’s better not to. Since such a "sea mistress" to keep at home is not at all easy.

The question "opened a pet store. Business is not going. What to do? "- 2 answers

So what kind of fish can you advise to beginner aquarists? Of course, the most unpretentious. Today, there are a lot of such undemanding in terms of care for the inhabitants of aquariums. Therefore, you can choose any kinds of fish, different sizes with any color.

The best types of fish for beginners aquarists

For example, you can choose a zebrafish as the very first inhabitant of a new aquarium. These mobile and peace-loving small fishes come in both medium and small sizes, they prefer to live in packs. It is desirable that the top of the aquarium covered with glass, because for these fish is characterized by a kind of jumping ability. It is also necessary to ensure that the danio “house” is spacious and well lit. You should also take care of aeration, because zebrafish need clear, oxygen-rich water. These fish are not exacting to food, and therefore can eat with equal pleasure, both live and dry food. Undemanding data inhabitants and the chemical components of water. Most importantly, the water should be fresh. In 2003, a genetically modified zebrafish fluorescent breed appeared on the world market. It was obtained by implanting in the DNA of the zebrafish embryo a fragment of the jellyfish DNA with the ability of biofluorescence.
Incredibly beautiful in the aquarium look barbs. Small fishes of this variety do not cease to amaze with their variety and magnificence. Barbs are characterized by high activity, while they are quite peaceful. They are undesirable to sit down to other inhabitants, with threadlike fins, for example, to the angelfish, as they can pinch their fins. The same applies to sluggish fish with so-called "voile" fins. The best neighbors for barbs are speckled catfish. And although the latter are not particularly beautiful, they can live in any, even in not quite clean water. They are friendly and can easily get along with other fish.
Swordtails are also good neighbors for aquarium dwellers, because they are endowed with qualities such as calm and peacefulness. One of their virtues is omnivorous. They can even live in small aquariums, although they need some room for maneuver. In their "home" must be present living plants, and it is desirable that some of them float on the surface.

The most unpretentious view

The main mistake that novice guppy lovers make is to keep several breeds in one aquarium at once, which is why the offspring turns out to be of little value. The championship in the nomination “the most unpretentious aquarium fish” certainly keeps the guppies. They are considered to be the most common aquarium fish, which attracts with its undemanding, as amateurs and novice aquarists. It is also noteworthy that the guppies were the very first of all aquarium pets in space. Experts have noticed that such fish in artificial conditions grow better than in natural waters. It is enough to get only a couple, and soon their number will increase many times, as these fish are viviparous. If there is no need for a large offspring, then a pregnant female is better not to be separated from the common aquarium. Fry will be the perfect food for other fish. For males, guppies are characterized by a large variety of different colors, although the females themselves are seemingly homely. But at the same time, they are quite unpretentious and feel great in any water, the temperature drop is not terrible for them.

Tip 2: What are the most unpretentious aquarium fish

Aquarium fish, like any other living creatures, need proper care and care. Cases of mass death of the inhabitants of the aquarium in novice aquarists are not uncommon. For the health of the fish there are no trifles. Everything is important here: the composition and temperature of the water, the level of illumination, the quantity and quality of food, the timely cleaning of the aquarium and much more. In order to avoid mistakes and disappointment at the initial stage of aquarism, you should prefer unpretentious species of fish that do not require special care, special knowledge and high costs.


1. One of the most unpretentious species of aquarium inhabitants is the well-known guppies - miniature viviparous fishes of various colors and colors. Guppies are highly resistant to water conditions, temperature fluctuations. Picky fish in the diet. And these creatures are extremely prolific. To keep the guppy fit even the smallest aquarium. So, for a comfortable dwelling of seven or nine individuals, only ten liters of water is enough. Due to modesty and ability to survive in difficult conditions, guppies were the first aquarium fish to be in space.

2. If guppies seem to you too ordinary, pay attention to the Sword. These bright coral fish will be a real decoration of any aquarium! Swordtails undemanding to the composition of water and food quality. However, these representatives of the underwater world have an aggressive character. Often males of swordtails, competing for food and females, arrange real battles in which a large number of fish die.

3. Invariably popular among beginner aquarists cockerels. These aquarium fish are distinguished by the bright color of the tails and fins, similar to the plumage of birds. For breathing males need atmospheric air, so if this type of fish is the only one in the aquarium, then you can do without installing a compressor. Both live food and artificial cereals are suitable for food. The only minus of the content of cockerels lies in their quarrelsome nature, therefore, if there are several males in the aquarium, fights and the death of the fish cannot be avoided.

4. Perhaps the most peaceful fish are catfish. Among all the aquatic inhabitants of the catfish, the most unpretentious, besides, they perform the role of orderlies, cleaning the soil from food debris and waste products. These fish are slow and do not pose a threat to their neighbors. However, it is not recommended to keep catfish in the same tank with predators and aggressors. When choosing somikov should pay attention to the corridor. This species, in addition to the gill, has intestinal respiration, which allows it to live for quite a long time in conditions of periodic shutdown of aeration.

5. Of particular interest are small schooling fish that can revive any aquarium. Among the most unpretentious are danios and neon. Danio is a small fish, as a rule, not growing more than five to six centimeters in length. For the content of six to eight copies of a small enough aquarium of ten liters. They are picky about nutrition: they eat both natural food (daphnia, bloodworms) and flakes. These fish perfectly coexist among themselves and with other inhabitants of the aquarium. Neon is also undemanding to food and easily tolerates a temporary lack of food. By their nature, these fish are very playful and peaceful, but they should be protected from more aggressive species. Neon requires a large amount of water. For ten specimens a 50-liter aquarium will become a comfortable habitat.


Природные породы аквариумных рыбок отличаются повышенной приспосабливаемостью и неприхотливостью к условиям содержания и качеству корма. Искусственные виды, как правило, более капризны и уязвимы.

При выборе аквариума стоит обратить пристальное внимание на качество стекла, герметичность, а также на запах, исходящий от емкости. Запах ни в коем случае не должен быть резким и химическим!

Несколько важных правил

Правило первое. Рыбка для маленького аквариума не должна быть хищной. Часто приобретают мальков, не думая, каких размеров они достигнут, когда повзрослеют. Therefore, you need to ask the seller about the maximum dimensions of an adult.

Rule two. Fish for a small aquarium should not be rare and expensive. In such containers, it is difficult to maintain a stable desired mode. In case of violation of ecobalance (for example, due to excess feed), they are the first to die.

Rule three. No need to get a lot of fish. A single individual, 5 cm long, requires approximately 4 liters of water. Easy to count: unpretentious fish for a small aquarium of 30 liters in the amount of 7-8 pieces. will feel quite comfortable.

Rule Four. There is no need to start individuals that are very different in behavioral factors. For example, some fish constantly move, while others are inactive.

Fifth Rule You need to start the fish with a uniform filling of the vital volume. For example, territorial individuals may occupy a larger capacity space, which will cause great inconvenience to other inhabitants. In addition, the fish must be combined vertically so as not to overcrowd one of the water layers (bottom, middle, top).

Fish spawning

Striped Sumatran barbus looks very good, especially mossy barb - a mutant of green color.

Danio fish are small and completely unpretentious. Cute voile cardinals are also small in size and are suitable for such containers.

The smallest fish for the aquarium, perhaps, are the neons of the Haracin family, but they are somewhat more expensive. But neon (red, blue or ordinary) is considered the most spectacular fish among all freshwater schooling representatives. A flock of 10-15 individuals will become a real decoration of any aquarium.

If you want to buy larger fish, you can stay on a pair of scalar or parrot pelvicahromis.

Small catfish (gold, mottled, green) get along well with any fish. They live in the bottom layer, feed on the remnants of food at the bottom, thereby cleaning the ground. And catfish antsistrusy, thanks to the structure of the mouth-sucker, clean the walls of the aquarium from algal deposits.

The number and composition of the inhabitants of the aquarium entirely depend on the preferences and the availability of finances of its owner.

The names of the smallest aquarium fish

Most aquarium enthusiasts can afford only small-sized aquariums. Such models, with a capacity of up to 100 liters, perfectly fit to the interior of the apartment. Such small tanks are easy to maintain and require little cost, as are the small aquarium fish that inhabit them..

Fish farming is a fascinating and at the same time complex process, the main thing in which is the result, namely, the contemplation of the colorful living underwater world. The advantages of large aquariums in this sense are high, however, compact options can successfully perform this decorative function. It all depends on how well you pick up its inhabitants - the smallest fish.

Viviparous small fish

A great option - breeding the most persistent fish - guppies. They are not the smallest, but they demonstrate a high survivability and are the most enduring of the schooling inhabitants of the home “reservoir”. Your aquarium will be filled with bright colors, thanks to the main beauty of these schooling fishes - the tail fin, especially if you get interesting specimens. A flock of 15-20 fish will color your aquarium with bright lights.

A gaggle of adult Endler guppies.

A great solution for settling a small aquarium will be the swordtails, which got their name, due to the fact that on the tail fin in the males during puberty a xiphoid process appears. Feeding the Swordsmen will not cause difficulties, because the food suits them varied: dry and lively and frozen. You should not breed them in aquariums with a capacity of more than 50 liters, because in these conditions swordtails can grow up to 10 - 12 cm. The most ideal recipe for breeding them: run a company of 15-20 waterfowl into 50 liters of water at a temperature of 20 - 25 and, voila . Your eyes are already pleased with the magnificent red, black, green, and even spotty and tiger representatives of this genus.

A flock of 10 miniature mollies of elegant black color will look very interesting. However, such refined beauty requires better quality care. The pledge that they will give you joy from their contemplation is a bright light and occasional salting of water, maintaining the temperature not lower than 20 ° С.

Calving fishes

Barbs (Sumatran, fiery, dark-haired ruby, and tiger) are widespread among this type of aquarium pet. They prefer live food and grow to about 6 centimeters. They are quite unpretentious, but they should be purchased in pairs. These smallest aquarium pets can not be settled with relatives of voilev forms because barbs are able to nibble their fins.

See how live barbs look like.

The presence of the smallest aquarium fish - danio rerio or danio inle will be spectacular. These most active and very playful small schooling fish prefer live or dry food, and their size reaches 3 - 5 centimeters. Excessive mobility of waterfowl, unfortunately, is dangerous for them. Often, danios jump out of their pool, so only closed aquariums are suitable for growing them.

Talking about the smallest fish for breeding, it is impossible not to mention the well-known neon. These smallest inhabitants of indoor ponds are famous for their amazing color, but rather neon luminous strip, which runs through the whole body. Like all small fish, neons are schooling, so it is worth to settle them in groups of 10 pieces.

Look at the neon tank.

Whatever schooling fish you choose, it is very important to understand that their attractive colorful appearance and cheerfulness depend on you completely. It should be borne in mind that the minimum allowable amount of water for each instance can not be less than 3 liters. Too many water dwellers will transform your source of inspiration and positive into a kind of “communal apartment” and will not in the best way affect their behavior. Maintaining an optimal temperature, a weekly water change of 20 percent, the presence of an aquarium filter, aeration, and the right food - these simple procedures will help you enjoy the contemplation of the brilliance of bright colors in the aquarium.

And here's another great selection of nano fish - look:

Residents for a small aquarium

And so, you read my article on the launch of a nano-aquarium, or you just wanted to start your own little water world for a long time and now you are thinking about who to settle there.

Quite a lot of options)

All the inhabitants of the underwater world can be divided into vertebrates, invertebrates and mollusks.

Vertebrates include various types of fish. To invertebrates - shrimps, crabs and crayfish. To mollusks - snails.

You can choose one of these kingdoms (for example, make a shrimp maker), or you can combine two or even all three.

The traditional is an aquarium populated by fish. Only here in a small aquarium you will not plant everybody, you will have to choose small schooling fish or one or two medium ones.

Possible options for colonization of the FISH Aquarium:

1. Petushki:

Very famous and common fish. Males are very beautiful, have luxurious fan fins. Females are less elegant, but also very brightly colored. Breeders are constantly working on breeding new colors cockerels.

They are satisfied with small amounts of water (but, you see, keeping the fish in an aquarium of less than 5 liters is both cruel and ugly). Water temperature - ideally 26 degrees. The cockerel breathes atmospheric air, swallowing it from the surface. Therefore, care must be taken that the air in the room is not too cool. You can cover the aquarium cover, but leave a few inches from the surface of the water.

Male males are very pugnacious, so it’s best to keep them alone or in families (1 male and 3-4 females).

The body length of an adult cockerel is about 6 cm.

2. Neons

Also known Russian fish. Neons prefer to live in flocks, so it is better to settle them in groups of 5 individuals.

The water temperature is 22-25 degrees (ideally), at higher temperatures, the lifetimes of these fish are reduced. In principle, neons are unpretentious, like soft water and an abundance of plants. Prone to obesity, so they should be fed very moderately.

Adult neon can reach a length of 4 cm.

3. Danio rerio:

As a rule, these small fish are always recommended for beginners. Moving, fun and unpretentious danios feel best in flocks. They can live in the temperature range of 15-30 degrees and be content with 1 liter of water per 1 fish (that is, even in a five-liter aquarium, you can run a group of 5 zebrafish). Easily spawn in an aquarium.

There are several color forms of this fish.

Body length up to 5 cm (but more often 3-4).

4. Guppy:

Probably, it is from this fish that aquarism begins for most people. It was the guppies living in three-liter banks that became frequent inhabitants of Soviet (and then Russian) apartments. They are loved by millions for their unpretentiousness (they can live even in the most extreme conditions), beauty (thanks to the many unique colors, everyone can find "the fish of their dreams" =)) and fertility (you can buy just one female, and in a month she will give birth to you 20 fry).

Viviparous guppies, i.e. they do not spawn, but give birth to live fry. They eat absolutely everything. Water temperatures are undemanding.

At first I liked them very much, but now they multiplied uncontrollably. It even annoys me that every week I find at least 20 newborn fry in the aquarium.

The males are guppies slender, with a bright body and a luxurious tail. Samochki larger, thicker, gray and inconspicuous. But there are quite beautiful purebred females.

Breeders are constantly working on new breeds of guppy.

Dimensions: male - 3-4 cm, female - up to 6 cm.

(last 2 pics are female)

5. Guppy Endler:

In fact, the same guppy. But Endler's guppy is a wild form that breeders did not manage to work on. Such fish are found in Venezuela. easily interbreed with simple guppies and produce very cute hybrids)

Endler's guppies are smaller than ordinary guppies: males reach a length of 2-3 cm. Look great in small aquariums with a dark background!

6. Corridor:

The so-called "speckled catfish". In fact, the corridors are very many species, just speckled - the most famous of them.

The corridors love the company, buy 3-5 at once. These harmless catfish do not exceed 5 cm in length, some species (such as the corridor panda) do not grow more than 3 cm at all.

Unpretentious, can live without aeration. The soil should be without sharp stones so that the fish will not hurt their delicate antennae. The optimum temperature of the content - 24-26 degrees.

Water volume: at least 3-5 liters for 1 fish.

7. Corridor Pygmy:

View of the corridors, which is worth to say separately.

Pygmies are small schooling fishes, seemingly greyish and inconspicuous, but very cute and interesting in behavior. They feel good only in a flock, they like clean, oxygenated water.

Unlike other corridors, they do not sit only in the bottom layer of water, but prefer to “flit” all over the aquarium, like a flock of birds.

8. Cardinal:

Prefers neutral water, rather cool (18-21 °). For 1 fish requires 3 liters of water. The fish are small, 3-4 cm, quite mobile. They love the abundance of plants, omnivores.

9. Micro disassembly:

An ideal fish for a nano-aquarium. Body length rarely exceeds 2 cm. Water temperature is 22-28 degrees, unpretentious to the composition of the water, 1 fish requires less than 1 liter of water. Unfortunately, micro-assemblies are now rarely available, and aquarists have been waiting for these fish to be delivered to stores for months.

10. Norman Blue-Eye:

Cute schooling fish that grow up to 3-4 cm. Their eyes glow brightly with neon light, which gives the aquarium a kind of dynamics and charm.

Peaceful schooling fish, water temperature 20-25 degrees. I live at a higher temperature, very active and playful.

And so, we looked at fish that would be happy even in a small aquarium of 10-30 liters.

Approximate settlement options:


• 5-7 Guppy Endler,

• 5 Norman blue-eyed

• 7 micro-sampling + 5 danio-rerio,

• 3 Endler guppies + 5 danios-rerio,

• 3 neon + 3 guppies.

• Family of cockerels (1 male and 3 females),

• 1 cock + 3 corridors,

• 10-15 guppies or Endler's guppies,

• 10-15 Norman blue-eyed

• 7 pygmy corridors,

• 5 guppies + 5 neons,

• 15 Danio-rerio + 15 microassembly,

• 10 guppies + 3 corridors,

• 7 neons + 3 corridors.

Here the possibilities are even greater) For example, such fish may be settled, which I did not tell about here. A pair of macropods, a couple of honey gouras, a pair of pelvicahromis or apistograms.

The remaining combinations - we look at 10 liters and multiply the number of fish by 3.

Naturally, it is better to run less fish than planned. Overcrowding is very dangerous for such small volumes. In any case, filtration, aeration and a weekly water change of 20-30% should be provided.

Now, shrimpers are coming into fashion - aquariums populated with freshwater shrimps.

Shrimps are unpretentious, cute and very interesting.

Aquarium SHRIMPS:

1. Cherry shrimp (cherry):

Small (up to 3 cm) red shrimp. Extremely unpretentious. It breeds well in an aquarium.

2. Amano Shrimp (Japanese Pond):

More than a cherry (up to 6 cm). Gray, perfectly fights with algal fouling. In an aquarium where shrimps live, the plants are always clean and well maintained.

In captivity do not breed.

3. Shrimp Crystal:

Small (2 cm), dear, rather demanding to water, but very beautiful shrimp.

4. Shrimp Cardinal:

Very beautiful and very rare shrimp. Considered difficult to maintain.

5. Yellow shrimp:

Unpretentious small shrimp bright yellow. If it is undernourished, it can begin to spoil the plants.

If you want to keep only shrimp (without fish), then you can plant a rather large flock in a small volume. For example, in 10 liters 20-25 shrimp-cherries will feel great.

Shrimps do not touch the fish, but some fish are not averse to eat shrimp. Therefore, the ideal neighbors for shrimp will be small fish, such as the Endler guppies, microassemblies, neons, corridors and Norman blue-eyes.

The calculation is approximately as follows:

20 liters: 10 shrimp-cherries + 5-7 guppy Endler (or other small fish).

Shellfish in an aquarium:

Some snails are also quite cute and even useful. They will be excellent neighbors for your fish or shrimp.

1. Helena:

Cute striped snail that feeds. other snails. It helps to get rid of the invasion of pond snails and coils that spoil the plants. For lack of "live food" eats the remnants of fish food. It breeds well in an aquarium.

2. Neretina:

Beautiful and useful snail. Helps to clear plaque from walls and plants. It lays its eggs, but the whites do not appear in fresh water.

3. Ampularia:

The most favorite snail, very often found in aquariums.

Unfortunately, some types of ampoulyaries spoil the plants. And there is a lot of dirt from them.


I tried to introduce you to creatures that will feel great in a small (10-30 l) aquarium. Aquarium with small nimble fish or business-like shrimp will greatly decorate your apartment or office. With proper and timely care, he will long please you.

About how to run the aquarium, I wrote in the article "The underwater world on your desk."

I repeat once again simple rules that will help you to always maintain your aquarium in good condition:

1. DO NOT HURRY! The launch of the aquarium should last at least 2 weeks (from the water up to the launch of the fish).

2. Down with artificiality! Plants, soil and decorations in the aquarium should be NATURAL. No plastic!

3. The filter should work around the clock !.

4. Water changes should be done once a week, at 20-30%. Never change all the water at once! Never wash the scenery with chemistry!

5. Feed the fish a little! One day a week - unloading.

6. If after you install the filter, there was a dregs - do not rush to change the water! All is well, the appearance of turbidity suggests that a balance has begun to be established. After a couple of days the water will be clean.

7. Do not overdo it with fish! Less is more.

8. Remember: an aquarium is a complex biological system. Do not climb there once again with your hands, do not make chemistry or other drugs.

9. Fish - also alive. And you are responsible for her life.

There is nothing difficult in aquarism. Learn to be patient, do not neglect the advice, do not forget to devote half an hour a week to your underwater world - and he will thank you. Coming home, you will enjoy the lush green plants and frolicking fish.

Successes to all who decided to start an aquarium!
