How to keep clown fish at home


Clown fish (or Amphiprion ocellaris) - this is a small tropical fish, which is known for its bright orange-white color and the ability to hide in the thickets of sea anemones. Whether you are an experienced aquarist or you just really like the cartoon “Finding Nemo”, caring for clown fish is a rather difficult task, and you need to know exactly what is required of you, before to get a fish. Fortunately, compared to many other tropical fish, the clown fish is unpretentious and easy to care for!

The content of the article

Clown fish is a very popular inhabitant of the deep sea among aquarists, a real handsome man, whom American directors made the main character of one of his best-selling films - the animated film “Finding Nemo”. How to contain this amazing fish, are there any purely individual recommendations for the care of amphiprion and its nutrition?

Clown fish are quite picky creatures, they feel great even in small aquariums. The best option for the underwater “little world” for a couple of these colorful creatures is an aquarium with a length of 80 centimeters, a width of 30-35 centimeters and a depth (height) of 40-45 centimeters.

When keeping amphiprions, as well as when keeping any other fish, it is necessary to carefully filter the water in the aquarium. For these purposes, an external or internal filter with activated carbon filler is quite suitable. It is quite acceptable for the process of filtering water and the use of so-called "living stones" - natural reef formations or, more simply, pieces of reef inhabited by living marine organisms.

Based on the fact that clown fish in nature live in salty sea waters, the water should also be salty in the aquarium. If you measure the level of water salinity (density) using a hydrometer, then its indicator should be equal to numbers from 1.021 to 1.023.

The optimum water temperature in the aquarium for keeping clown fish is from 24 to 26 ° C. Among other things, the amphiprion aquarium should be well lit.

Feeding and other content recommendations

Clown fish are best fed with ready-made dry food, although they will not refuse frozen shrimp or pieces of shellfish. Frequency of feeding - 2-3 times a day, in small portions.

In order for clown fish to be truly comfortable, they should also contain an aquarium coral polyp in the same aquarium. Actinia is an indispensable companion of amphiprion, at the same time its house and protector. By the way, clown fish spawn also under the reliable protection of their eternal companion.

To properly care for a coral polyp, you need to follow some simple rules. For example, you should know that sea anemones, like clown fish, feel comfortable only in a well-lit aquarium. As food, polyps can be content with small pieces of sea fish, squid and shellfish.

In order for this incredible creature not to harm itself, it is necessary to ensure that it does not come close to the working filter pump.


The warm waters of the Pacific and Indian Ocean are the main places where clown fish live. Amphiprion populations are observed in East Africa, and a significant amount lives on the coast of Japan.

In nature, the life expectancy of fish is ten years, and in favorable conditions of the aquarium environment, where individuals regularly feed and are not attacked, this period increases by one and a half to two times.

A characteristic feature of the amphiprion lifestyle is a “friendship” with a poisonous anemone. Together, the clown fish and sea anemone form a mutually beneficial symbiosis, where everyone protects and cares for each other.

Clown fish and sea anemones exist perfectly together, despite the fact that this species of sea anemones is poisonous. Their tentacles contain enough poison to cause painful burns in humans, or kill medium-sized fish. However, the clown fish has immunity, which produces an unusual way: first, the fish lightly touches the tentacle with poison, thus obtaining information about it. Then the amphiprion clown secretes mucus, which protects it from stinging tentacles.

After developing immunity, the amphiprion settles near the sea anemone, performing a ventilated function and eliminating the remnants of food, and the anemone protects its neighbor from predators. Thus, anemone and clown fish are an excellent example of mutually beneficial cooperation.

Aquarium Maintenance

Keeping fish in an artificial pond will not cause any difficulties if you follow the care recommendations. Clown fish is very unpretentious, so it is very popular with aquarists.

The only drawback of the striped resident is the change in character. Captive detention often provokes outbreaks of aggression in these fish, so you should not populate them with peace-loving relatives. In addition to this nuance, the clown fish in the aquarium feels good if the following parameters are observed:

  • the reservoir contains corals, grottoes and live sea anemones,
  • water temperature - 26C,
  • density - no more than 1,023,
  • acidity - 8, 4 pH.

It is also necessary to regularly clean the pond of dirt and food debris; water is replaced weekly, at least 1/10 of the volume. Aeration and filtration must be installed in the tank.

Particular attention is paid to the diet of amphiprions - they can eat dry and live food, the main thing is to remove the remnants of food. Experienced aquarists note that a clown fish eats well algae and slices of squid.

In the neighbors to the amphiprions, frogs, lion fish and eel should not be landed.


Clown fish are born exclusively by males, and only after the formation of the pack do some individuals change their gender to female. The largest male representative becomes a manufacturer. Amphiprions lay eggs near anemones or grottoes, and carefully guard them until the fry are born, which hatch after 10 days.

Newborn fry are immediately planted, but if this is not possible, the male will protect and preserve the offspring to maturity. It should be noted that fry have weak immunity, therefore, resettlement from the aquarium will exclude the possibility of infection from other residents.

Clown fish interesting facts:

  • matriarchy reigns in a flock of amphiprions,
  • after the release of the animated film “Finding Nemo”, where the main character looks exactly like an amphiprion, the popularity of the fish has greatly increased,
  • representatives of this phenotype are born males, and if necessary change sex,
  • amphiprions are the only fish making a noise in the aquarium: they grumble, click and make other funny sounds.

Aquarium fish clowns are funny and cute creatures that will brighten any pond with bright colors. They are unpretentious, therefore, subject to simple rules of care and hygiene are able to please their owner for a long time.

Habitat features

The clown fish lives in the warm coastal areas of the Pacific and Indian oceans. This is a typical representative of tropical fauna. Clown fish, whose description of life can be found quite often, lives in the sea in the tentacles of sea anemones. These anemones are poisonous, but they do not touch this fish. These two animals have mutually beneficial cooperation: the clown attracts predators with its appearance. Throwing themselves on fish, predators themselves become anemones. What remains of the anemone's meal goes to the clown. In addition, among the tentacles, he feels protected. Clown fish in the aquarium also need anemones - if there are few of them, stronger individuals crowd out weak ones from polyps. However, if the aquarium has grottoes and shelters, sea anemones are not so necessary.

Maintenance and care

We must not forget that the aquarium clown fish is a sea fish. Maintenance of such aquariums is much more difficult. But all efforts are worth it. A well-designed marine aquarium is also not the cheapest pleasure. Equipment for maintaining tropical marine conditions, together with a suitable capacity, will cost about $ 600.

Minimum size of the aquarium for keeping clown fish: 80 cm - length, 45 - height, and 35 cm - width. In such an aquarium you can keep up to three fish. It should not stand in a light passage through the passage, as the fish are afraid of cooling.

No matter how many fish live in your home, it is necessary to ensure reliable water filtration. The clown fish in the aquarium prefers clean water, so all impurities must be removed in a timely manner.

The ideal salt level for clowns is 1.021-1.023. It’s best to have a hydrometer on hand to be sure of salinity. Ammonia, nitrates and nitrites should be minimized. Water replacement by 20-25% should be carried out weekly. The optimum temperature for clowns is 25-26 degrees. Good neighbors for these fish are seahorses.

Clown fish is completely picky about food. These individuals will perfectly eat special dry food, but if possible, it is better to feed them frozen - artemia or shrimp.
