Clownfish is a peaceful creature. However, if the territory is not enough, it begins to oppress other fish, including their own kind. Conflicts can be minimized if we provide all inhabitants with the necessary area and shelters. What kind of fish are kept in an aquarium with clowns:

  • Butterfly fish,
  • Goby
  • Chromis,
  • Cardinal
  • Doggy,
Under the conditions of captivity, clown fish often become aggressive, so it is undesirable to share them with peace-loving varieties.

Neighbors clowns should not show aggression. It is allowed to plant fish with an average level of aggression, provided that their size will be inferior to the size of amphitrions.

Adults are fed 2 times a day. Young stock - 4 times. The entire volume of food offered should be eaten within 3 minutes. Leftover food removed. Which feed is suitable for clown fish:

  • Small shrimp
  • Squids
  • Shellfish
  • Ready feed for marine fish
  • Artemia
  • Small pieces of fish

Breeding

In captivity, the sea clown fish actively breeds. The most difficult stage is to save the offspring, providing it with proper nutrition.

Place for throwing caviar can serve as aquarium artificial grottoes or corals.

5 days before spawning, the male begins courtship of the female. At this time, the eggs are formed in her stomach. The place for spawning is thoroughly cleaned with fish. As a rule, it is a small area under actinia or corals.

The female spawns at the beginning of the day and produces up to 800 eggs in one laying. The male fertilizes the eggs and removes unfertilized eggs. A week later, fry out of them. After two weeks, the young individuals seek shelter.

400 fry need from 300 liters of sea water. Water should be settled with a large amount of plankton to feed the young. After three days, you can give them the larvae of leaf-legged crustaceans and crushed dry fish food. Usually part of the offspring dies or is eaten, both in captivity and in nature.

Fry born into the world should be transplanted into a separate small aquarium

Fry are grown in a separate, rearing, aquarium. Water purification and aeration are carried out to a minimum. The filtered water is reused. This recommendation will help to keep the maximum number of individuals. Active reproduction of plankton (the main food for juveniles) cannot be maintained in too clean water.

A flock of clown fish consists of a main pair and several young fish of indeterminate sex.

In general, the level of difficulty of launching and maintaining a marine aquarium is more complicated than a freshwater one. If an aquarist has experience in keeping marine fish, acquiring a clown fish will not be difficult for him. You need to buy it from trusted suppliers who deserve trust.

Where does the clown fish live?

In the world there are about 30 species of amphipriones. In its natural environment, the clown fish lives for about 10 years, in aquariums twice as long. This is explained by the fact that in captivity there is no constant danger that awaits amphiprions in nature in the face of predatory fish. Clown fish lives in the waters of the Pacific and Indian Oceans, as well as near East Africa, off the coast of Polynesia and Japan, in the reefs of eastern Australia. Amphiprion is a fairly small fish, not more than 20 centimeters in length. It lives in dense thickets of sea anemone, it is quite a good neighborhood, because thanks to the mucus on the plant, the clown fish hides from predators among the sea anemone tentacles. In turn, the fish take care of the coral, ventilating the water around it and removing the remnants of undigested food. Interestingly, these two organisms are very connected with each other, and the clown fish never swims away from its neighbor, the sea anemones.

Clownfish - description and photos.

All fry clown fish born males, but during the life of a fish changes its sex, if the female of the pair died. It is characteristic that the males are much smaller than the females, the head is short, the body is oblate from the sides, the back is high. The upper fin is divided, its front part with prickly spikes, and the back fin soft. It is this distinction that visually separates the dorsal fin, and in appearance it seems that there are two of them. In food, clown fish is unpretentious, mostly microscopic algae and small crustaceans are food for amphitrione. Clown fish live in flocks, at the head of which is always the old and large female. In the period of spawning, the fish lays from a few hundred to a thousand eggs on flat stones, next to the neighbor actinia. Caviar ripening takes 10 days. While the fry develop, the clown fish courageously protects them.

Aquarium clownfish.

Clown fish is quite popular with aquarists because of its bright color and interesting behavior: you can watch them for hours, losing track of time. Another huge plus in the content of clown fish in an aquarium is their unpretentiousness in comparison with other coral-looking fish. But even this seemingly cute little fish has a minus - in captivity, the clown fish becomes quite aggressive. And this should be taken into account when sharing it with other fish in the aquarium. The color of aquarium fish exactly repeats the natural, large black stripes alternate with red or orange and white. The fins have a black border, and the iris around the eyes is bright orange. The only difference: the stripes can have a different shape.

Clownfish - content in the aquarium.

Before buying a clown fish, it is necessary to land anemones in the aquarium, add a few corals, it is in them that the clowns hide. For one pair of fish, 50 to 70 liters of water is enough, and the temperature should be around 25 to 27 degrees. Water change should be carried out 4 times a month. Feeding is carried out several times a day in small portions so that food does not remain in the aquarium. As food can be suitable as dry feed for aquarium fish, and live or frozen brine shrimp, small pieces of fish and squid, shrimp, and algae (for example, spirulina).

Spawning fish clown.

Particular attention should be paid to the breeding of clown fish. As a rule, spawning occurs in the evening, this is due to the fact that moonlight activates the behavior of males. In nature, fish clowns lay their eggs under the anemone either on the coral or the grotto, in captivity - it can be a clay pot turned upside down, less often a saucer. Before caviar throwing, the place is thoroughly cleaned for several days. The process of laying caviar takes about two hours. An interesting fact is that only the male takes care of the future offspring from the beginning of spawning. He carefully waves his fins with caviar, removes non-living eggs, protects from enemies. From the first day, the fry who have become a candidate starts feeding on their own. Strips on the body of the fish do not appear immediately, but at the end of the first week of life. If, in addition to clown fish, there are other types of fish in the aquarium, then it is advisable to plant the fry into a separate aquarium, since proximity to other fish can lead to the death of a part of the fry. They can simply be eaten by other fish. Feeding fry consists of the same diet as adults.

Clown fish are very susceptible to diseases such as fungal and bacterial infections, trematodes, ectoparasites. Therefore, special attention should be paid to the quality of the water in the aquarium.

Content

There are no particular difficulties in caring for amphipriones, you just need to follow some specific rules, not too different from the content of other varieties of fish.

Artificial sea water in an aquarium should have a density of about 1.02, with about 34 grams of salt per liter of fluid. Due to the fact that this species of fish in natural conditions lives in tropical seas, where the water is warm enough, the temperature in the aquarium requires at least 26 and not more than 31 ° C.

Cleanliness in the aquarium is maintained using a biological filter, and periodically organic particles can accumulate on the surface of the soil, which should be removed with a siphon. The most suitable soil for amphipriones is coral sand, the particle size of which should be from 3 to 6 mm. The size of the sand layer is recommended 8 - 9 mm.

Fish need to replace every week part of the water in the aquarium - about 25%. Care should be taken to ensure that the chemical composition of fresh water does not differ.

Amphiprion - clown fish!

Clowns are not at all capricious in terms of nutrition. It is necessary to feed them several times a day, giving food in small portions. Due to the fact that all the remnants of the meal of fish get anemone, waste from these inhabitants of the aquarium is minimal. Therefore, unlike other representatives of the underwater world that live near coral reefs, amphipriones are suitable for not too expensive and quite simple equipment for water purification.

Clowns feed on all the traditional fodder that can be found in pet stores. A special treat for them is frozen food. In connection with the fastidiousness of such inhabitants, they feed on almost everything that fits in the mouth.

Classification

The entire genus of amphiprions has about 25 species, but no more than 10 of them are possible to be kept in a home aquarium. This is due to the fact that some fish live either in places that are too difficult to catch or their fishing is generally prohibited.

The most common species in captivity are:

- clarkii - chocolate fish, the most common among the entire genus. The color of her body ranges from a dark yellow to almost black. She has a slightly elongated body, a small mouth and small teeth,

- ocellaris - a representative of this particular type is the main character of the cartoon about Nemo fish. With all his pretty appearance, he is quite aggressive. Their belligerence, aggressiveness and self-confidence are simply amazing, and it is explained by the fact that the fish can hide among the tentacles of the anemone at the slightest danger, becoming inaccessible,

- melanopus - they are very similar to some other species. The main difference of this species is the ventral fins, completely painted black. Representatives of this species are not recommended to be kept together with other species of amphipriones,

Amphiprion - clown fish!

- perideraion - a characteristic feature of a pink clown is a light strip running along the back of the fish. There are less common than other species of the genus Amphiprione. The fish is not as bright as some other representatives of this genus, but, nevertheless, it is fairly easy to contain.

Appearance of amphipriones

Clown fish are distinguished not only by their bright color, but also by their body shape. They have a short back, a flattened body (laterally). These fish have one dorsal fin, divided by a peculiar dimple into two parts. One of the parts (the one closest to the head) has thorny spikes, and the other, on the contrary, is very soft.

The body length of amphipriones can vary from 15 to 20 centimeters. On the skin of these fish a lot of mucus, it protects them from stinging cells of anemones, among which clown fish spend quite a lot of time. The skin of amphipriones has a contrasting color, always bright shades, with a predominance of: yellow, blue, white, orange colors.

Habitat features

Clownfish live in warm coastal areas of the Pacific and Indian Oceans. This is a typical representative of tropical fauna. The clown fish, whose description of life can be found quite often, lives in the sea in the sea anemones tentacles. These anemones are poisonous, but they don’t touch this fish. These two animals have mutually beneficial cooperation: the clown attracts predators with its species. Rushing to fish, predators themselves become prey of anemone. What remains of the anemone meal goes to the clown. In addition, among the tentacles, he feels protected. A clown fish in an aquarium also needs anemones - if there are few of them, stronger individuals force out weaker polyps. However, if there are grottoes and shelters in the aquarium, anemones are not so necessary.

Appearance and Description

Coloring of sea clown fish differs in saturated and bright shades. Appearance can be presented in dark blue and even bright orange colors. Somewhat less common are specimens that have an uncharacteristic bright red or light lemon yellow color.

It is interesting! Absolutely all the fry clown fish are originally males. However, over time, the fish, under certain circumstances, changes its sex and becomes a female.

Males of this species are much smaller than females. The average length of a marine amphiprion in nature does not exceed fifteen to twenty centimeters. Clown fish have a short head, a laterally flattened body and a high dorsal part. Upper fin divided. Its front end has thorny spikes, so visually it may seem that their pair.

Habitat - where the clown fish lives

Worldwide, there are about thirty species of clown fish. In a natural habitat, a marine clown fish can live for about ten years, but when creating comfortable conditions, aquarium amphiborones live, as a rule, one and a half to two times longer than wild relatives.

In natural conditions, clownfish inhabit the waters of the Pacific and Indian Oceans.. A large population is observed near the territory of East Africa, and also lives near the coastal zone of Japan and the Polynesian islands. A large number of amphipriones can be found near the reefs of eastern Australia.

Amphiprion lifestyle

For amphiprion, a mutually beneficial symbiosis with almost any kinds of anemones is very characteristic. At first, the clown fish easily touches the surface of the poisonous sea anemone, which stings the fish and thereby declassifies the exact composition of its mucous coating.

As a result, the amphiprion reproduces such a composition as accurately as possible and gets an excellent opportunity to hide between the tentacles of poisonous sea anemone, fleeing from numerous enemies. Clown fish carefully take care of sea anemone, performing a venting function and removing all undigested food residues.

It is interesting! Throughout his life, amphipriones do not move a long distance from "their" actinium.

Criteria for choosing an aquarium

Before you buy clown fish, you need to take care of buying a good and sufficient in volume aquarium. For a pair of amphiprions it will be enough to select an aquarium with a volume of 50-60 liters.

It is interesting! Clown fish or amphipriones are the only "noisy" aquarium fish. Adult individuals of this species click, grumble quietly, and also make other, no less funny sounds.

A mandatory condition for the cultivation of clown fish in captivity is planting anemones in the aquarium soil, as well as several corals. This rule is due to the need to hide clowns. The most correct, it is considered to be rectangular or panoramic shape of a home aquarium.

Water requirements

Clown fish are very susceptible to some diseases, among which infections of fungal and bacterial character, trematodes and various types of ectoparasites are especially common. In order to preserve the health of aquatic inhabitants, it is necessary to pay special attention to the quality characteristics of aquarium water.. The average temperature should be 25-27 ° C. A change of 10% of the water in the home aquarium should be carried out weekly. Replacing a quarter of the water from the total can be done only a couple of times a month.

Care and maintenance of clown fish

It is very important to observe the rules of fish compatibility inside the aquarium, as well as regularly monitor the water parameters and the conditions of keeping decorative aquatic animals. Rays of direct sunlight should not fall on an aquarium with clownfish. An aquarium filled with water needs to stand until it’s settled for about a day.

Important! All newly acquired individuals must be placed in quarantine aquariums, where during the week you can determine the presence or absence of infectious diseases.

You also need to deal with any instances that are suspicious in behavior or appearance.

Nutrition and Diet

Feeding clown fish should be carried out several times a day, giving the aquarium pet food in small but equal portions.. Food should not remain in the aquarium water, as in this case, the feed rot and rapid water spoilage occurs.

The main ration of amphiprion can be represented by special, high-quality dry food intended for the cultivation of ornamental aquarium fish. It is very well suited for feeding clown fish protein food live or frozen Artemia, small pieces of sea fish or squid, as well as algae, including spirulina.

Buy clown fish

It is not recommended to purchase clown amphipriones caught in natural, natural conditions.. It is these so-called wild specimens that are most often realized by those already afflicted with many diseases, including oodinosis, cryptocaryosis and brooklinellosis. Among other things, it is adult individuals that most often die when changing the natural content to captive conditions.

Owner reviews

A children's animated film called Finding Nemo made clown amphiphones very popular with domestic aquarists. Clown fish are capable of being quite strongly attached to each other, and they spend almost all the time together, even sleeping nearby.

It is best to keep amphipriones in a pair or a small flock, but it is necessary to set aside particularly aggressive individuals. Many aquarists contain in one sufficiently large aquarium, clown fish with other species that are comparable in size and do not belong to the category of predatory fish. Amphiphriones of almost any species are completely unpretentious, therefore, subject to aquarium hygiene and proper feeding, they can please their owner for many years.
