Predatory aquarium fish

Quote: "Who wants to live - he must fight. And who does not want to resist in this world
the eternal struggle, he has no right to life. "

Dear reader, this article is devoted to predators of the freshwater aquarium. On the Internet, there are a lot of tales about this issue, to the extent that the Angelfish are ferocious predators of the aquarium.

Therefore, before you lay out our selection of predatory fish, let's determine with you in terms.

All animals can be divided into predators and herbivores:

Predatory - These are those who eat only meat.

HORROWAYS - These are those who eat only plants.

Now it is worth noting the fact that in nature it is very rare to find a PREGNANT ANIMAL, which feeds exclusively on meat. For example, cats! Cats are predators, but all happy owners of Barsik and Murzikov know that their pets love to chew grass and home plants.

The same situation is with the fish. In a huge aquarium kingdom it is very difficult to find a meat-eating fish. Perhaps this is not. I do not renounce, but the diet of all aquarium fish includes both vegetable and animal feed.

From the above we can conclude - Of predatory aquatic fish in the true sense of the word does not exist. Speaking of the predatory nature of fish, the word aggression is most likely appropriate. But with aggression there is its own catchup - after all, even guppies show intraspecific aggression, although they don’t pull on predators at all.

Thus, it is possible to deduce a certain vector of understanding of the phrase: "PRESENT AQUARIUM FISHES" - these are overly aggressive, large, territorial aquarium fish, in the diet, which mainly includes meat food.


Many people know that the family of cichl fishes are for the most part aggressive, territorial fish, especially this statement applies to African cichlids. In some species of cichlids, there is even the most severe intraspecific aggression, which is manifested not only in males in relation to each other, but also between the male and female, for example, as in Labeotrofeus Arevavas. Sometimes it comes to the fact that the joint maintenance of the female and the male becomes simply not possible, since the latter slaughters an individual of the opposite sex to death.


Astronotus - the most popular and common cichlid, having a predatory disposition. Large, aggressive fish, which is best kept in the species aquarium and a pair. Astronotuses are perceived by all small neighbors as food. And with large types of clashes occur constantly. For an adult couple, it’s almost unreal to plant someone.

Fish can reach 35 cm. Astoronthus is the birthplace of the Amazon, the system of the rivers Paraná, Paraguay, Rio Negro. The volume of the aquarium for such tsikhlin need from 300 to 500 liters.

Water parameters: pH 6.0-8.0, temperature 22-28 ° C. Of course, aeration, filtration, and regular water changes (weekly 30%) are necessary. Particular attention should be paid to filtering - it should be powerful (the second filter will not be superfluous). The aquarium can be decorated with large stones and snags, the decor should not be sharp.

CYCHLIDE KNIFE Haplochromis long-nosed

It has a territorial character and is jealous of those who come to its territory. Long-range cichlus rushes to various shiny objects. In clashes with other fish catches the eye, for which he received the nickname "eye eater". These fish in nature are fierce "killers."

Comfortable parameters of water: temperature 25-27 ° C, dH 8-20 °, pH 7.5-8.5. aeration, filtration, weekly substitution? parts of fresh water with the same parameters.


Piranha predators are literally armed to the teeth. Teeth lamellar and sharp as a razor. Piranha's jaws are powerful, an adult can bite a wooden stick as thick as a human finger.

It should be noted that aquarium piranhas lose their natural aggressiveness, while maintaining their formidable appearance. But for some reason people’s fear of this does not disappear.

Piranhas are a great aquarium fish, therefore it is better to keep them with a school of 5-8 fish of the same size and age.


These somas are not just predators, but "fierce killers." In their homeland, in Asia, they exterminate all the fish that are in their reservoir, and when no one is left, they crawl out onto dry land and crawl to the nearest new reservoir behind the “new victim”, while eating on land "insects and small frogs. We must pay tribute - in the aquarium, these somas behave much calmer.


The fish is not livable grumpy character, shows aggression. You can keep a tetradon with large mobile fish. Some authors recommend keeping this fish only in a species aquarium.

For a flock of tetradons you need a large volume of aquarium from 150 liters. Fish leads a twilight lifestyle and is afraid of bright light. Therefore, the aquarium is equipped with a variety of stones, caves, snags and floating plants.


Toward the close of the article, I will give an example that clearly shows the rapacity of any living creature, even the most innocent.

Akantoftalmus - a small loach wormfish. Peaceful harmless inhabitant of the aquarium bottom. But ... in nature, if an acantophthalmos is caught by a medium-sized predator, a sharp spike will cause it to immediately spit out and remember this striped fish. Big birds or catfish often swallow Acantophthalmos completely. What, very sorry then !!! A small fish breaks through the stomach wall of the animal, and sometimes goes outside. The obscene predator dies.

The struggle for life, alas, many forces to be predators and cold-blooded killers. And the world of aquarium fish - this is just a small springboard for fighting for life and procreation.

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

Carnivores of the aquarium

Predatory aquarium fish bring the sharpness of sensations and bright colors to the home underwater world. These fish will require more attention, and in return will deliver unforgettable emotions to the owner due to the manifestation of their predatory habits and natural instincts.

Predatory fish are larger in size and can show aggression among their relatives. The most popular are aquarium cichlids, piranhas, polypteruses, astronotus, discus and scalar.



Perch-shaped cichlids are among the widespread aquarists' favorites around the world. The fishes come from African and South American countries are divided into Malawian, South American, in groups there are mbuna and utaka cichlids. These predatory fish have a beautiful color and developed intelligence, depending on the variety, their length varies from 7 to 80 cm. They are characterized by unusual behavior, cichlids are able to observe the actions of a person, recognize the owner and react to his hand movements.

These aquarium fish love a large space, but rarely get along with other fish. Cichlids can seriously damage living plants, so it is better to place artificial decorations and plants in an aquarium.

Turquoise akara

Turquoise akara

These South American cichlids are quite common among aquarists who call them "green terror". In length, their tall body reaches up to 30 cm, males are larger than females and have a turquoise hue with a pearl shade. The head is large with thick lips and medium eyes. On the sides there is a black spot, and on the gill covers there is a drawing in the form of strokes of green-pearl color.

Males have a massive forehead with fatty growth that increases with age. These aquarium fish are territorial, their contents is possible with cichlids of similar size. Fish are susceptible to disease if the temperature is below 24 ° C. Akars have a tough character, but are not outspoken fighters. It is not recommended to share them together with citrons and horn.

Krenitsichla cardiac

Krenitsichla cardiac

For the maintenance of these fish, capable of growing up to 25 cm, will require a large aquarium of 400 liters. These predatory fishes have an elongated body, on which a longitudinal dark stripe is located, and there are spots on the sides with a light rim. These cichlids feed on small fish, amphibians and crustaceans.

Krenichichla differs in that, having not found a free refuge, she chooses any shelter she likes and expels the previous owner. During the hunt, the fish first lurk at the bottom, and then with lightning attack the victim.

Long-nosed haplochromis

Long-nosed haplochromis

This representative of the cichl family is also called the knife cichlid. Aquarium dlinnorylye haplochromis reach in sizes up to 18 cm, the body is sky-blue with a red-orange border on the fins. The following behavior is typical for this fish in the event of a conflict: when it clashes with other fish, Haplokhromis catches their eyes, for which he received another name "eye eater". These cichlids are also partial to the shiny objects in the aquarium.

Fishes are aggressive towards small neighbors, large males can live peacefully with medium-sized fish such as scalar and barbs. The aggressiveness of the long-eared haplochromis can be reduced by increasing the volume of the aquarium and placing more shelters in it.

Content in an aquarium

To begin with, the aquarium should be positioned correctly, as this is important. It is best to place it in a well-lit and quiet place. Capacity dimensions also matter, the bigger the better. Predatory aquarium dwellers require optimal water parameters, the joint keeping of cold-water with warm-water fish is not allowed. Water should be saturated with oxygen in sufficient quantities, as well as important filters and aeration.

As a decoration of the water landscape, you can use snags, stones, algae, pots. Plants are needed with large roots or planted in a pot, suitable broadleaf sagittariya and ekhinodorus.

Cichlasomes and Akaras are the easiest to keep, while smaller cichlids require skills and experience in keeping aquarium fish. In no case should you put a hand with fresh cuts into the aquarium, as predatory fish can attack and cause serious damage. Basically aquarium predators are unpretentious in care and rarely get sick.

Blue discus


Predatory fish usually run into an aquarium with similar fish in size and conditions. Usually, predators do not just attack their fellows and peaceful fish, there are a number of certain factors:

  • satisfy hunger;
  • division of territory;
  • during the spawning period;
  • male conflict (natural selection).

But sometimes for other incomprehensible reasons, predators such as catfish, flip-flops and black-striped cichlids can attack small fish. And some fish and in particular sea predators are aggressive towards fish that are similar in color to them.

African cichlids can more or less get along with South American cichlids, eels, the catfish and the astronotus. Dwarf cichlids, which can coexist with pelmichromis, apistogram and lamprologus, are relatively peaceful-minded.

It is necessary to take into account the factor that Cichl fishes may experience stress if there are no other inhabitants in the upper layer of water. For the top layer, we can recommend a group of Australian iris irons such as glazolepis, melanotenii iridescent and three-stripes.


Practically for breeding all types of predators a separate spawning is recommended so that the fish can safely and safely breed. Aquarium water parameters must comply with the required indicators for the possibility of reproduction. It is better to fish the fish several weeks before spawning and feed them well with live, high-quality food.

Cichlids also have unique parental qualities, most species bear eggs in their mouths and caring for their offspring with care. Formed fry grow fairly quickly and feed on small cyclops, daphnia and artemia. After hatching, the fry of the parents are deposited in a common aquarium so that they do not eat their offspring.



Aquarium predators require adequate nutrition, otherwise they will attack their neighbors, pulling out their fins to each other. It is necessary to provide them with quality food with live food, sometimes replacing it with raw meat and other surrogates. The best food for them is live fish, which should be regularly included in the diet of predators. It is not advisable to feed them the meat of mammals, predators and birds, as this leads to fish obesity. Beef heart and liver can be given in small amounts. But the best fit is shellfish, shrimp, frozen fish, tadpoles.

There is an unspoken rule in aquarism: in the aquarium should be released as many small fish as food for predators, as they eat them at a time. Small fish should not be among predatory fish until they are hungry again. The size of the small fish should be such that the predator can swallow it whole.

You can not overfeed fish, it can lead to toxic aquatic environment and the reproduction of parasites. The dosage of feeding depends on the type of fish, most often they are fed in small portions several times a day.

The behavior of carnivorous inhabitants of the aquarium during feeding is an interesting sight. Some predatory fish wait in ambush and slowly approach the prey, while others actively catch up and seize the prey.

Predatory aquarium fish always attracted aquarists with their exotic outward beauty, but they were especially interested in intriguing behavior. It is much nicer and more fun to watch the big fish, as they are like real aquatic pets.

Predatory aquarium fish

Predatory fish aquarium make home aquarium exotic. There are many types of predators. The larger the size of such fish, the more interesting it is to watch them.

What features have predatory aquarium fish?

These fish deliver much more trouble than the usual "peaceful" fish. Before buying predators, experts advise to carefully weigh the pros and cons. Predatory fish in the aquarium require close attention. They constantly show their natural instincts.

The most popular are piranhas, cichlids, girinohaylusy and fish with the strange name "Indian Ocular Knife." In very large aquariums often snakeheads are bred. Under natural conditions, large individuals reach 1 meter in length and their weight can be 7 kg. Such fish look very colorful.


Together with snakeheads, you can only keep big fish, such as polypteruses, tarakatums and astronotus. Otherwise, the predator just swallow them. Some species of fish may exhibit intraspecific aggression.

Precautionary measures

Predatory fish can not be settled along with the usual. In one aquarium, it is permissible to run fish with similar habits and conditions of detention. In isolation, predatory aquarium fish do not behave as aggressively as in nature. However, it is not worth checking.

It is not recommended to lower your hand in the aquarium if you have fresh cuts. As practice shows, it immediately attracts the attention of predators. They can cause serious injury.

How to feed predatory fish in the aquarium

They need to provide good nutrition. This type of fish is recommended to give live food. You can replace it with raw meat and various surrogates.

Predatory aquarium fish in a state of hunger even begin to attack each other. Sometimes they pull out the fins. To avoid this, it is necessary to feed them in time. Natural food for them is live fish. It must be included in the diet.

You can purchase fish for feeding in specialized stores. We do not recommend buying it in unverified places. It may be a carrier of pathogens.

How to feed predatory fish in an aquarium

Many aquarium fish predators are distinguished by unusual behavior during feeding. They arrange an ambush, gradually getting to the victim. Others can freeze in place, waiting for small fish. There are predatory fish that catch up with their "feed." They catch up and grab the victim. Watching the habits of aquatic predators is quite interesting.

What are the dangers of live food?

The main negative aspect is the possibility of introducing parasites and diseases. Pathogenic microorganisms can be in the tissues and entrails of live food. Crustaceans, which are found in fresh water, sometimes contain larvae of parasite worms (helminths).

helminth worm

If live food is grown in an open system where there are no fish, then the probability of the presence of pathogens is lower. However, it is impossible to determine the quality of feed by eye. Eliminate hazards helps special water treatment and purification of live food. However, it is impossible to fully rely on such procedures.

Thus, feeding predatory aquarium fish is always accompanied by the risk of infection in the aquarium. We advise you not to feed predators with meat of birds and mammals. This leads to obesity. It is acceptable to give them beef liver or heart in small doses. Excellent food are shrimps, clams, tadpoles, frozen fish.

Feed predatory aquarium fish should be in moderation. They cannot be overfed. Excess food begins to decompose in the aquarium. Because of this, ammonia is formed. As a result, a toxic environment is created inside the home water reservoir. Pollution of the environment leads to the rapid reproduction of parasites. In this embodiment, it will be necessary to constantly change the water.

How often do I need to feed predatory aquarium fish

The frequency of feeding depends entirely on the type of predator. Environmental factors also matter. Many fish in nature eat food continuously. In aquarium conditions, fish can be fed several times a day. At the same time it is necessary to give small portions of food.

Some predatory fish in the aquarium can swallow large prey entirely. In this case, they are fed no more than three times a week. Sometimes they themselves refuse extra food. Below is a video of feeding predators aquarium fish.

Where better to place an aquarium

The location of the aquarium is important. Before acquiring predators, find out what conditions they need. For example, piranhas are shy in kind. Therefore, they should be located away from sources of noise. Ideal to place the aquarium in a quiet and well-lit place.

Important nuances

Predatory aquarium fish need a large aquarium with an optimal water temperature. The composition of water also matters. The larger the individual, the more space it needs. You can not keep in the same aquarium cold-water and warm-water fish. In addition, home water should be equipped with a filter. There should be enough oxygen in the water.

Attention should be paid to landscape design. Algae, snags and pebbles can be placed in an aquarium. The maintenance of predatory aquarium fish is a fascinating activity that brings a lot of pleasure.

Ternesia: content, compatibility, breeding, photo-video review

Thorns is a small, popular dark silver fish. It can be found in any pet store and in many home aquarium. Its unpretentious content, ease of breeding, peaceful nature - deserves the attention of aquarists beginners.

Latin name: Gymnocorymbus ternetzi

Synonyms: Black, mourning

In English: Black skirt tetra, Black Widow tetra, Black tetra.

Order, family: Characteristic.

Comfortable water temperature: 21 - 24 p.

"Acidity" Ph: 5,7 - 7,0.

Rigidity: up to 6-16 °.

Aggressiveness: not aggressive 20%.

The complexity of the content: easy

Compatibility: The terntions calmly get along with all non-large and non-aggressive fish, such as: gourami, scalars, large tetras, sword-bearers, danios, corrido-dogs, sac-haired catfish and others.

Not compatible: It is not recommended to take them to the "veil" fish, slow and frankly small fish. It is not recommended to contain them with neons, guppies and other bipod. At the same time, the terntions are not compatible with large and territorial cichlids: tsikhlazomy, astronotus, with other predatory fish. It is noticed that when keeping a terence in a flock, they can bite each other. See article compatibility of aquarium fish.

How many live: Life by aquarium standards is short-lasting, with good conditions of detention can live up to 6 years. On average, live 3-4 years. Find out how much other fish live HERE!

The minimum volume of the aquarium: Thorns can be maintained even in an aquarium from 10 liters, in such an aquarium you can put 1 well, a maximum of two fish. However, they are schooling fish and therefore it is better to keep them in a group of 35 liters in a tank. About how much you can keep fish in X liters of aquarium, see HERE (at the bottom of the article there are links to aquariums of all volumes).

Care requirements and ternation conditions

Fish do not need supernatural conditions of detention. Observance of optimal parameters of aquarium water is the key to their well-being. However, it is worth remembering that:

- necessarily need aeration and filtration, weekly substitution of up to 1/4 of the volume of aquarium water. If you change the water to them less often than once a week, nothing terrible will happen, the fish are hardy and adapt to any conditions. And if you have a large aquarium, then the water for terntion can be changed once a month.

- the fish need free space for swimming, if you have a small aquarium, it is better not to densely populate it with plants and select swimming areas.

- Aquarium decoration, can be anything: snags, stones, grottoes and other decorations. But since the fishes have a dark color, it is better to decorate the back wall of the aquarium with a lighter background, the ground is also not black. Shelters (grottoes, caves) are absolutely unnecessary for ternations, sometimes they hide only in the thickets of plants.

Feeding and diet ternii

Omnivorous - not whimsical in food, not prone to overeating. With pleasure they eat live, dry food, substitutes. Live and frozen food (bloodworm, artemia, daphnia, etc.) - adore. Food is taken by fish mainly in the middle layer of water. Fallen to the bottom of the food will also be eaten.

Feeding aquarium fish should be correct: balanced, varied. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses. Article "How and how much to feed aquarium fish" talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing - feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company "Tetra" - the leader of the Russian market, in fact, the range of feeds of this company is striking. In the "gastronomic arsenal" of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc. Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry. Detailed information on all Tetra feeds, you can find on the official website of the company - here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state - this will help avoid the development of pathogenic flora in it.

In nature, live:

Area - Brazil, Bolivia: the river Mato Grosso, Rio Paraguay, Rio Negro. They live in ponds with dense vegetation, which is why, if the home aquarium allows, it is better to decorate it with live aquarium plants, and in the center to provide an area for free swimming.


The body of the termination is flat, the color is silver-striped - 3 black stripes are located across the body. One of the bands passes through the eye. Fins, except anal - transparent. Anal fin - black fan-shaped. The length of the terns is 4–5 cm. The females are larger and wider than the males, with a fuller abdomen.

Fish energetic, mobile, schooling. Shy of fear, they can turn pale and hide in a secluded place.

Varieties of terntions

In addition to the terns with a natural color - silver-black, in my lifetime I met a selection veil shape and color variants of gold (white) and pink (caramel) ternets. Here they are in the photo.

Veil Throne Gold Thistle

Pink thorns

And of course, the well-known trend of Glo-fish has not bypassed these fish for many.

Glofish - These are genetically modified fluorescent fish.

The first fish that have been mutated is Danio rerio. As a result of experiments received fish with red, green and orange fluorescent color, which becomes brighter and more intense with ultraviolet light.

In 2011 genome-modified ternation was derived

A bit of history:

Europe, thorns appeared in 1933, and were introduced to Russia in 1946.

Described by the Belgian-British zoologist and ichthyologist George Albert Boulinger (Boulenger) in 1895.

Cultivation, reproduction of a ternation

An important point in the propagation of termination is the selection of producers. They can only be individuals maturity - 8 months and the size of 3-5 cm. All other small or too large in the producers are not suitable.

A spawning 40 liter aquarium is settled as follows: moss-like plants are laid out on the bottom: key moss, Javanese, stump, etc. Fill the aquarium with fresh water at 5 cm. The temperature of the water is maintained at 24-26 ° C. Good aeration is desirable.

On the third day, when the water is infused and becomes absolutely transparent. Manufacturers are planted in the spawning aquarium and begin to feed them abundantly with live food. At the same time there should be no residues.

At 3-6 days spawning occurs. The male begins to chase the female throughout the spawning game and at the moments of a short-term stop the female sweeps up to 30 eggs one-time, which are immediately poured with milt. Spawning lasts about 3 hours. The number of eggs for one spawning is about 1000 pieces.

After spawning, the producers are immediately removed from the spawning aquarium, otherwise the roe will be eaten.

The incubation period for caviar is about one day. During this period it is necessary to raise the temperature of the aquarium water to 28 ° C.

The larva of thorns is small, barely noticeable. At first it hangs on the plants and the walls of the aquarium, and the 3rd day begins to swim.

Juveniles are fed standardly grated live food, live dust.

In the process of growth, the fish are sorted, small and defective are destroyed.

See more details The breeding forum: what caviar, larvae, care feeding fry and so on.

Diseases of termination.

It is very stable fish and can tolerate harsh conditions of detention. But you should not experiment. The guarantee of absolute health is proper maintenance.

Terrestitia is susceptible to all typical diseases of aquarium fish and there are no nuances in their treatment. They are treated standardly: by raising the temperature to 30 degrees, by methylene blue, tripaflavin, baths with salt, etc.

For correct and correct treatment, it is necessary to diagnose the disease, and then apply the necessary procedures. This section will help you: Aqua medicine, fish diseases.

Cichlids are predators of the aquarium.


But the main condition is necessary - the presence of a pair (male and female). All South American cichlids are monogamous, i.e. form stable pairs without taking other fish into their family. Cichlids are the most beautiful aquarium fish. They are very diverse in color and body shape. In some, the body is oblong, as in the loach (teleogram), in others, on the contrary, it is strongly compressed from the sides, disc-shaped (symphysodons and pterophyllus).

In most species, the body is massive, slightly compressed from the sides and extended in length. The head is large, with a steep forehead, and with males the forehead becomes even steeper with males. In most cases, cichlids belong to territorial species, differ in aggressive behavior towards their relatives and other fish, but they are caring parents, which is nonsense for fish .

Magnificent color forms, curious behavior and relative simplicity in content determined their success among aquarists all over the world. Fish from the tsikhlov family are perhaps the most intelligent among all other species. Almost all cichlids spawn in an aquarium where they live. If the conditions are good, there is a constant and diverse food, then sooner or later these fish will spawn.

COLIDS - What to feed

A healthy diet of aquarium fish - a guarantee of well-being and active life. For many, this is not a secret, and real aquarists try to feed their fish only with natural food. I do not argue that the dry combined food is convenient, practical, does not particularly pollute the aquarium and has, probably, a lot of advantages. But, there is one more thing: you do not know what is stuffed into this dry food, right? Fishes will surely eat him, because there is simply no other food in the aquarium. A hungry fish of choice in this case does not have.

So I used to feed my cichlids only dry food. I was glad that Akaras, labidochromis, dolphins eat the entire one-off portion well. But after a while she began to notice that cichlids began to tear off the plants in the aquarium and eat. Maybe the grass is edible, or the fish lacked something, but it became a matter of concern for me. The appearance of aqua rapidly deteriorated.

Immediately I began to look for the reason for such barbaric behavior of my fish and, having scrolled through several sites in aquarism, I found that all self-respecting aquarists make up food for cichlids themselves. The composition surprised me a little, but I decided to try.

Here, it turns out how to feed the cichlids, or rather the list of products:

- 100 g of any fish (I used pink salmon, as there are few small bones in it)

- 100 g of green peas (took frozen and thawed)

- 100 grams of corn (as well as peas)

- 1 teaspoon of semolina

- a quarter of the cabbage of cabbage (you can use any other lettuce leaves)

- 100 g shrimp

I boiled the fish and separated it from the bones. Peas and corn thawed and excess moisture poured. The leaves of Beijing cabbage scalded with boiling water. Boil the shrimp for 10 minutes without salt and peel.

Then all these prepared products skipped through a meat grinder with a fine mesh and carefully mixed with semolina. Then she took a simple plastic bag, laid it on a cutting board and laid out the prepared food in the bag. Distributed the entire mix of the package so that the width of the plate of feed for cichlids does not exceed 3-4 mm, because it is easier to break off and feed the fish. Then the package, along with the board, was put into the freezer and then it got out, snapped it apart and fed it with its balanced natural food to its cichlids in the aquarium.

I will say right away: such an abrupt change of food was not to the liking of the fish, they grabbed the food and immediately spat it out - they got used to dry substitutes. But after a week (and the features of Akara), already by the rustling of the package, they understood that now they would be fed and swam closer. Thus, having transferred my cichlids to natural food, I began to notice that their behavior had changed noticeably. The lethargy disappeared, the fish became more curious, more active, and surprisingly, both the labidochromis, the blue dolphins, the akaras, and the angelfish immediately began to spawn! This is some kind of miracle!

I would venture to suggest that changing feed so dramatically affected the behavior of cichlids. And now if anyone is interested in the question: what is the right way to feed a cichlid in an aquarium? I answer immediately: only natural food! No dry mixes!

But every aquarist decides for himself what is better for his fish, although you have tried to eat dried fish or dry salad or peas? Fu, disgusting! And fish have to eat this in the form of substitutes, because they have nothing else to do. In the wild, CICHLIDES can find everything they need, but in an aquarium, all useful products to fish must be provided by an aquarist, otherwise the fish begin to hurt and that the consequence is to die. But I think it's up to you to decide.

Reproduction and breeding

Spawning in cichlids can occur at any time of the year, but it is desirable that it be spring or summer, as in ordinary water bodies it is possible to catch living dust or cyclops. If the eggs are removed from the producers, spawning can occur at intervals of 15 days, and if the eggs and fry are left, the gap can be up to two months.

In each cichlid species, fertility varies considerably. In some, it may be 100 fry, as the parent bears the spawn and fry in the mouth, and for those who spawn at a stone or a plant, the number of descendants is measured in thousands.

Most species are simply diluted; it is enough to raise the water temperature to 26-32 degrees. The composition of water does not play a role for many fish, although for some species soft water is needed. When picking up neighbors for your pets, you need to consider not only who the cichlids live with, but also the temperature range, the size of the fish, their aggressiveness, and food. Most cichlids only spend their youth in flocks. With the onset of puberty, they are divided into pairs.

In a large aquarium, where there are many shelters, cichlids spread in the corners and the victims can be avoided. Malawian cichlids can be kept in flocks, if you give them the likeness of a reef. For the Tanganyik trophies, shelter is strictly contraindicated. And the maintenance of small fish living in schools, together with most cichlids, is simply impossible! Cichlids are, first of all, a predator, eating any fish less than itself.


Since one of the largest schooling inhabitants of your reservoir is aquarium fish, cichlids, their maintenance implies a large “pool”. It should be at least 100 liters, and not at the expense of height - these fish are kept at the bottom or in the middle layer. The main thing in the aquarium - the length and width. The second prerequisite is continuous aeration and filtration; in a little saturated with oxygen and not too pure water, cichlids at first lose the brightness of the coloration, and then start to hurt.

As the soil is better to choose sand. Thanks to him, again reduced turbidity. The layer of soil should not be thicker than one and a half centimeters. All aquarium fish cichlids need shelters, and some species, especially when spawning. Clay shards from pots with stowed edges, snags and decorative stones with caves are quite suitable.

It is better to choose the latter so that they almost reach the water's edge - then the cichlids will develop the upper layers of their reservoir. If you live aquarium fish Malawian cichlids, vegetation should be almost completely absent, as in natural habitats. Let the bottom be better sown with stones. For those species of cichlids that dig the ground, algae must be chosen with powerful roots, and even planted them in low pots so that their fish do not pull out of the soil.

Amazingly beautiful, beautiful, unpretentious, bold - all these words can be applied to the cockerel aquarium fish. Aquarium cockerels have a bright variable color. Males, of almost all types of cockerels, have chic, veiled fins. And their content and breeding does not represent any complexity.

That is why cockerels are among the most popular fish among beginners in the aquarium world, as well as among professionals, who contain beautiful breeding forms, exposing them to competitions.

To understand the beauty and temper of these fish, I’ll give below a literary description of the behavior of cockerel fish in nature from I. Sheremetyev’s book: “Along with beautifully colored gouras, a grayish-green fish doesn’t immediately catch the eye. Her body is 6 cm long, slightly compressed with sides, elongated. On the sides there are turbid longitudinal stripes with a greenish sheen.

And the same gray, inconspicuous fish approached the fish. And suddenly, as if something had flared and shone in a small body. The body and splayed fins have become emerald. The fish opens the gill covers and goes to meet the guest. Who is it - the female or rival - the male, the fish can determine only when he sees what the stranger will answer. The female is in front of a gorgeous male, obeying, placing fins. If she is not ready for spawning, she immediately flees. If two males meet, their intentions will be more serious than can be imagined. Mutual posing begins, demonstrating brightness, playing brilliance and fin sizes.

This can take several minutes, and sometimes an hour. If one fish turns out to be half the size of the second, then it leaves another area. But, if males are the same size, then the first blow will be made sooner or later! Within minutes after the start of the fight, the fins of a weaker male hang down in pieces, the gill covers are broken, the body is covered with bloody wounds. Fishes do not bite, and having opened their mouths so that their teeth stick out ahead, with all their might they drive dozens of needles into the body of an opponent. After some time, the opponent is defeated, ... the male who won the fight, does not allow him to the air and the surface. The loser is killed! "

Let us take a closer look at these amazing representatives of South Asian reservoirs.

Latin name: Betta splendens;

Russian name: Cockerel fish, Siamese cockerel, cockerel, chicken, betta, fighting fish;

Order, suborder, family, subfamily, gender: Perciformes -Perciformes, Anabantoidei, Osphronemidae, Macropodusinae, Betta

Comfortable water temperature: 25-28 ° C.

"Acidity" Ph: It does not matter, but comfortable 6-8;

Stiffness dH: does not matter, but comfortable 5-15 °;

Aggressiveness: cockerels - Betta relatively peaceful fish - they can not be called predators. However, they have a strong intraspecific aggression and territoriality. Keep two males in a small aquarium is not possible. The dominant male will surely kill the weaker. Two or more males can be maintained only in large and wide aquariums, while fights for territory and females still cannot be avoided. In addition, males often show aggression and to a "disliked" female during spawning.

The complexity of the content: easy;

Cockerel fish compatibility: in addition to the previously mentioned intraspecific aggression, the aggression of fish extends to all small, clumsy and voile fish. Therefore, you can keep them, only nimble, active fish that will be similar in size. As a recommendation, it is possible to advise in the neighbors of the males: corridors (speckled catfish), danios, molines, swordtails, other nimble petilles, tetras.

Males are not compatible with cichlids, the family of goldfish, other labyrinth fish are not desirable. Not compatible with snails, they eat small snails, and large ones cut off their whiskers.

In addition, when combining fish you should always take into account the similarity of conditions and water parameters, for more information on the compatibility of aquarium fish, see HERE!

How many live: Cockerel fish are not aquarium long-livers, their age is short - only 3 years. Find out how much other fish live HERE!

The minimum amount of aquarium for cockerel fish

The question of the volume of the aquarium for these fighting fish is a separate topic.

Alas, almost all pet stores sell these luxury fish in 250ml. glasses, while sellers tell people that these are “unique fish”, they say they do not need oxygen, filtration, that they feel great even in a glass !!!

Do not believe the sellers of pet stores, their task is to sell the goods, and what will happen next with the fish, with you and the tears of the child who saw the cockerel floated up with a belly up - DOES NOT INTEREST THEM !!! And yet, you would know how many cockerels do not live by the pet store until the time of purchase !!! You would sincerely feel sorry for these innocent fish !!!

Yes, of course, cockerels are hardy fish, in natural habitat they live in muddy, silted, oxygen-free rice fields. But this does not mean that they can be kept in a small glass with water. Firstly, because the conditions of keeping of any animal should be as close as possible to the natural living conditions. Monkeys must jump in trees, birds fly, and fish swim !!! When the cockerel fish just hangs in a glass, dropping the fins - this is actually a sad sight. Secondly, in the cup, vase and other small vessels there is no biobalance at all. In the rice field, for example, various biochemical processes take place that purify water from various poisons (ammonia, nitrites and nitrates), these processes are absent in a glass with water, the poisons accumulate, the immunity of the fish weakens and it dies. Biological equilibrium in artificial conditions can be achieved only in spacious aquariums, and the more, the better.

So, the minimum amount of aquarium (decorative vase, etc.) for cockerels should be 3 liters. To call such a vessel an aquarium is difficult in all senses, and therefore, if we talk about creating a full-fledged aquarium, the minimum volume for one individual should be 5-10 liters. In such an aquarium, you can put a mini-filter, such an aquarium can be beautifully — naturally, you can plant aquarium plants, set up a bio balance, and taking care of such a reservoir is much easier than washing the “pot” weekly, while delivering great stress to the fish. A good volume for a pair of Bette is considered an aquarium from 20-30l.

About how much you can keep the fish in the X aquarium, see HERE (at the bottom of the article there are links to aquariums of all volumes).

Requirements for the care and maintenance of cockerel fish

From the above, we can conclude that in one, a small aquarium, you can contain only one male cockerel. If the aquarium is large - from 100l. You can try to plant the second male or make transparent partitions in the aquarium, for example from plexiglass, pre-drilled holes in them to circulate the water in the aquarium.

In addition, I advocate the creation of a natural - natural environment in an aquarium. The aquarium can and should be decorated with stones, grottoes, snags, as well as living aquarium plants. The lighting should not be very bright, preferably the presence of filtering. The aquarium itself should not be filled with water to the brim, you need to leave 7-10 cm and be sure to cover the aquarium. All labyrinth fish and cockerels in particular breathe atmospheric air, swallowing it from the surface of the water. In the absence of airspace or access to the surface of the water, the fish will suffocate. A lid is needed to ensure that the air swallowed by cockerels from the surface of the water is not too cold.

An aquarium with cockerels can be equipped with artificial plants, but still, if you have the opportunity, purchase live aquarium plants. With live plants, the aquarium looks more natural, the plants themselves contribute to biological balance, and the males can also use them for spawning and creating a foamy nest. Of unpretentious plants for cockerels can recommend: vallisneria, rogolini, cryptocorynes, other not complex plants.

Feeding and diet of cockerels: they are not whimsical in food, they are happy to eat both dry and live food (Artemia, bloodworm, etc.). The males eat any brand-name dry food, but advanced aquarium brands have developed special ones for them - individual foods that are best suited. Feeding aquarium fish should be correct: balanced, varied. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses. Article "How and how much to feed aquarium fish" talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing - feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company "Tetra" - the leader of the Russian market, in fact, the range of feeds of this company is striking. In the "gastronomic arsenal" of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc. Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry. Detailed information on all Tetra feeds, you can find on the official website of the company - here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state - this will help avoid the development of pathogenic flora in it.

In nature, live: Southeast Asia: Indonesia, Thailand, Cambodia, Malaysia, Vietnam. They live in stagnant, oxygen-free waters - puddles, ditches, rice fields.

Description: Very beautiful fish, its veil tail and fins just fascinate. The color of the fish is different. The most common ink color with a reddish tint. Males are colored much brighter, fins are longer than those of females. The size of the fish is 5-10 cm. The body is laterally compressed, elongated, oval. They have cycloid scales, pointed pectoral fins, upper and tail fin of a rounded shape, the lower fin originates from the head and ends at the base of the tail.

The history of cockerel fish

The first mention of the fish dates from the beginning of the nineteenth century, it was then that the people of Siam paid attention to these small, but lively and aggressive fish. Then the Siamese began to cross wild individuals Betta and got a new kind of fish, calling it "biting fish." A couple of copies of these "pieces" in 1840. King of Siam handed over to Dr. Theodor Cantor, who in 1849 gave them the name Macropodus pugnax. After 60 years, the British ichthyologist Charles Tate Regan renamed them "Betta fish", arguing that the Macropodus pugnax species already exists in nature.

It is known that the cockerel fish appeared in Paris in 1892, in Germany in 1896, and in 1910 appeared in the United States with Frank Locke from San Francisco, California. Through the selection of these fish, he received a "new" fish, calling it Betta Cambodia - one of the first color variations of Betta Splendens. The history of the appearance of Bette in Russia is not truly known. There are several versions. The first is associated with aquarist VM. Desnitsky, who allegedly in 1896. brought from Singapore exotic species of fish and plants, but it is not known for certain whether there were any cockerels among them. The second version says that the aquarist V.S. Melnikov approximately in the same period spread a number of labyrinth fishes in Russia. By the way, a competition for the best fighting fish was established in his honor. And the latest version says that the fighting fish were brought in by the Frenchman Seysel, and all descendants from Russia and Europe went from his fish.

Types of Bette and Petushki selection forms

The first thing I want to say is that the cockerel fish (Betta splendens) is one of the Bett species. Bette species should be distinguished from Betta splendens breeding forms. On the Internet, everywhere breeding forms of a rooster are given for species, which is not correct!

So, the Bette's species include: Betta picta (Betta picta), Betta striped (Betta taeniata Regan), Betta smaragdova (Betta smaragdina Ladiges), Betta untamulata (Betta unimaculata), Betta black, she’s also the dwarf, Cockerel black, she’s black, she’s black, she’s black, she’s black, she’s black, she’s black imbeIIis ladiges), Cockerel (Betta splendes).

And here, the selection forms of the Cockerel (Betta splendes) include:

In size and shape of the fins:

- Vualekhvosti warrior fish or "veil rooster"

- Deltatail fighting fish

- Giant or royal fighting fish

- Crescent-tailed warrior fish

- Round-tailed warrior fish

- Crescent-tailed warrior fish

- Deltatail fighting fish

- Flagtail fighting fishes

- Poster fighting fish

- Crowntail fighting fish

- Poster fighting fish

- Crosstail fishes

- Two-tailed fighting fish

- other

By color:
Multicolor "multicolor", two-color, one-color.

Reproduction and breeding aquarium cockerel fish

It is not difficult to breed these fish - it does not need any special conditions or, for example, a hormonal injection. In fact, under optimal conditions, spawning can occur in the general aquarium.

It is much more difficult to find a good pair of producers than to spawn itself. And if we talk about breeding breeding of cockerels, then the issue with the selection of parents arises squarely.

General information about spawning and breeding cockerels.

The sexual maturity of the cockerel reaches 3-4 months. From this period they can begin to breed.

Sex differences in fish are pronounced - males are larger than females, their fins are much larger and males are, as a rule, brighter than females. In addition, the female ready to spawn can be distinguished by the white "grain", "star" in front of the anal fin - this is the egg-deposit, as well as by the large abdomen.

pictured male and female cockerel

An aquarium for spawning may not be large from 10 liters, the water level in which should be 10-15 cm. A spawning aquarium should not have soil and is equipped only with shelters for the female, for example, with crown, as well as with small bushes of perististoistnye plants, for example, with roetail. You also need to use plants that float on the surface of the water: duckweed, piste, water-colored plant These plants are used by the male in the construction of the so-called "foam nest".

The temperature in the spawning tank should be in the range of 26-30 degrees Celsius. Different sources, write different data on the temperature regime for spawning Bette. Taking into account the analysis, I think that 28 degrees is the norm. This temperature is optimal and makes it possible to increase it by a couple of degrees, thereby stimulating spawning.

Spawning and soft water is used for spawning aquariums. Soft water is an incentive to spawn. You can soften the water aquarium chemistry - preparations containing peat, and other methods. In addition, in the spawning aquarium is recommended to throw a leaf of almonds (see Herbal medicine for fish and aquarium).

Before spawning, the producers sit for a couple of weeks, and are abundantly fed with live food. After spawning in the aquarium, the first place the male, which begins to settle. As soon as he begins to build a foam nest, a female with caviar is brought to him !!! The presence of calf in the female can be determined by the rounded abdomen.

If the spawning process does not start or the male does not pay attention to the female, the spawning should be stimulated: by softening the water or replacing the water with fresh water, raising the temperature by 2-3 degrees. If after these manipulations, spawning does not begin, you can try to plant another male in the presence of the male (if you have one).

But, usually the above described problems with breeding cockerels do not arise, in the evening the male already finally builds a nest, and in a day the calf already matures in it.

IMPORTANT!!! Stimulating fish in a spawning aquarium with live food is prohibited. At the time the producers are in spawning, they are not fed at all in order to avoid contamination and unwanted fungi and bacteria.

The process of spawning itself is very interesting. It begins with the fact that the male swims up to the female, hugs her and squeezes 2-5 eggs out of her. Eggs begin to fall to the bottom, the male quickly collects them in his mouth and places them in a foam nest. This "hug and spin" process is repeated several times.

A visual indication that the spawning is over is the male’s circling over the foam nest and the female’s seat in the shelter. As soon as this moment has arrived, the female is removed, since in the eyes of the male she begins to carry a threat to the offspring, which is why he can kill her. The deposited female is abundantly fed.Further, all the care of the clutch and the offspring takes the father! The main thing at this moment is not to disturb him. After one day, the larvae will appear, and after another day the yolk bladder will dissolve in the larvae and they will begin to swim.

You can remove the happy "father" and start feeding the fry with living dust by infusoria, or, for example, as some members of our site do it with melted water from Artemia frost. You can also try dry fish "baby food", for example, Sulfur Micron. Such feeds are either diluted in a bowl and the resulting suspension is poured into the spawning unit, or they take the feed at the tip of a finger and, grinding it in water, feed the young fish. Food in the aquarium should be present constantly. When feeding with live food (ciliates), water does not change, and when feeding with dry food, 80% of water is replaced daily in order to avoid contamination and mortality of the young. To maintain cleanliness in the aquarium, you can place snails ampoule or coils.

In the future, young cockerels are gradually (3-4 days) transferred to larger feeds, starting with Artemia nauplii, etc. After about two weeks, you can begin to try to give "adult" feed.

Aquarium fish catfish predator or not?


This species of fish belongs to the family of Crabfishes, or Callicht Callichthyidae. This family is a member of the Somo-Shaped (Siluriformes) squad. Representatives of the family - medium-sized fish living in the South
The distinguishing feature of this family is two rows of bony tiled plates on the sides of the body. The plates serve as a kind of shell, which is a good kind of protection from enemies, predators.
Three pairs of small antennae are placed around the small mouth near the armored catfish. In aquarium catfish the swim bladder is complex, it also partially performs the function of the lungs. Because of this, the fish occasionally rise in the aquarium to the surface of the water and trap air in their mouths.
Aquarium fish somiki such as, Somik speckled (Corydoras paleatus) in the literature are also described as somik ordinary and kallicht.
Homeland - South America (Argentina, Brazil, Paraguay, Uruguay).
Somi contain in the domestic conditions since the second half of the XIX century and to this day have deserved popularity.
The body length of the fish is 5-8 cm. In catfish, males are smaller and slimmer than females. The front part of the catfish body is wide, the back is narrowed laterally to the caudal fin. The back is convex, the abdomen, especially in males, is flat. The color of the back and sides is olive or grayish-brown, the belly is yellowish. The body and fins are covered with large dark spots. The male has a dorsal fin, pointed, and the female has a rounded appearance. After the dorsal fin, closer to the tail, is a small fatty fin. Practically all of the crustaceans of the catfish have bony plates on the sides, and antennae near the mouth.
Aquarium fish Somiki very unpretentious. These are calm, peaceful, friendly fishes. Most of the time, these fish spend on the bottom, where they constantly dig in the ground, choosing from it the remnants of uneaten food. Keeping the fish in the aquarium is better for the group, which should be spacious, and the water level in it was low (up to 25-30 cm). Coarse river sand is best suited for soil. At the back of the aquarium on the sides it is desirable to plant plants that have a well-developed root system. For fish, it is necessary to provide shelters in which there should not be narrow cracks. Water for the aquarium is suitable for any hardness, must be weakly acidic, slightly alkaline or neutral. Water temperature 16-24 ° C. Aquarium catfish well tolerate long-term increase or decrease in temperature. Catfish are omnivores and eat almost any food that they find at the bottom.
For breeding fish take a female and two males, they are deposited in a small aquarium (8-10 l) spawning. To stimulate spawning, fresh water is added, aeration and a decrease in temperature in the spawning pool by 1-2 ° C are necessary. Spawning fish is very unusual. The female lubricates the male milt, which she gathers into the mouth of the prepared substrate (which is a well-lit section of aquarium glass or leaves of plants). After that, the female begins to transfer the eggs to the substrate, which, in small portions, sweeps out several eggs and keeps the pelvic fins with folded pinch. Thus, almost all eggs are fertilized. After spawning, the fish are removed from the aquarium, and the water temperature is raised by 2-3 ° C. The trimmed and fertilized eggs develop slowly, the fry begin to hatch at the end of the second week. They feed on small food, which sinks to the bottom. The albino and veil form of catfish are derived by aquarists. Veil catfish have enlarged fins, while albinos are characterized by red eyes and light color (which is white or yellowish-white).

Rather, they are orderlies - they pick up from the bottom what falls from the top of the feeder and do not allow water pollution. Not counting the fish? It happens. Last year, we jumped out of the heat one by one, and “dried out” on the floor faster than we found it. They did not know who to think (they didn’t think of somics, they are very harmless), and then they all became witnesses of another throwing out.

Valya Zayusha

Look near the aquarium. I felt so strange yesterday. I'm sitting in the kitchen eating. I think I'll go to the fish. the devil lured me. has gone. I watch one danyushki not. looked, groped no! I feel that something moves near my feet, I look Nazoc (danio rerio). here so chyut not dead!
and he is my very best. he is a crossed zebrafish (zebra, brindle or striped) and pink zebra turned out to be some kind of red with dark gray stripes ...
oh what am I!))))
