Keep them recommend flocks of at least 4 individuals. But we must be prepared for the fact that they have a strict hierarchy and there are cases of cannibalism. They can grow up to 30 cm. So the aquarium will need a very large one.

  • Iris

In the color of these fish there are a variety of colors and their most breathtaking combinations. The fish are especially beautiful in the morning. It is very important to remember that any stress and deterioration of conditions leads to the fact that the fish turns into silver-gray. At the same time you need to keep at least 6 fish together.

  • Rasbor wedge

Mobile, unpretentious, not very large (up to 5 cm), peaceful, beautiful - all this is about them. With a long and rather high body, flattened laterally. The transition to the tail is sharp. The tail itself has a deep notch. Фон тела может быть серебристым с рыжеватым или розовым отливом либо золотистым. Отличительная особенность - это большое клиновидное черное пятно в нижней части тела, за что расбора и получила свое название. По этому пятну можно определить пол. У самок оно размытое, а у самцов имеет острые углы.It is recommended to keep a large flock of 10-15 individuals in an aquarium of 50 liters.

  • Rainbow Hemigrammopetters

Freshwater fish growing to about 6 cm. The body is long, flat, rather high. The fin on the back is long, crescent. There is a fat fin. The color is transparent, yellowish-gray, cast in green, blue or gold. Fins are yellowish. Along the body passes a dark stripe, bordered by white. The character of peace. Contained a flock in a spacious aquarium.

  • Congo

The males of these fish are bright green with a ribbon-like protrusion on the tail and a dorsal fin in the form of a pigtail. Females are yellowish brown with transparent or yellowish fins. The scales are large.

Summing up

In conclusion, let us give advice: it is better to have fewer different fish, but more specimens of the same species. It is completely undesirable to keep pairs of schooling fish, because they will wither away from stress and will die prematurely or turn into arrogant individualists.

We tried to cover and briefly describe as many schooling fish as possible, but, of course, not all were included in our list, and this is impossible in one article. That's why if you have something to add or share experience, we will be happy.

Type of aquarium fish and compatibility of different species (table)

Getting a pet store, the newcomer is just lost - so many fish, they all like it in their own way, I want to settle in the new aquarium as many handsome men as possible. But the choice of neighbors has its own subtleties. Let's consider how aquarium fish are compatible with each other.

Species compatibility

The species compatibility table clearly shows which animals are fully compatible with each other, incompatible, or partially compatible under certain conditions. Consider the principles on which the table is built.

  1. Conditions should be well suited for all inhabitants of the aquarium.
  2. You can not put together a predator and prey.
  3. Type of aquarium fish with a calm and sluggish nature should not coexist with fast and active fish. They'll starve and get stressed.
  4. The inhabitants of the aquarium should be proportionate. Even the most peaceful fish will eat everyone who fits into her mouth.
  5. Some fish show aggression and can attack both neighbors and members of their own species. It is necessary to take into account the particular behavior.
  6. One type of aquarium fish can not live without a flock of their own kind, the other - without a pair, and the third prefers loneliness. This should not be forgotten if you want to avoid fights or stress.

So, consider what types of aquarium fish are, some aspects of their content and compatibility. In one article it is impossible to describe all types of fish, so we will focus on the most popular representatives and the general characteristics of groups.


Apistogram dwarf cichlids are popular species of aquarium fish. Photos show that these little fish look like bright tropical butterflies. Apistograms do not need a large amount of aquarium, plants do not damage and are quite calm. They can be kept with other peaceful fish - sword-bearers, patzilia, guppies, mollies, neons, rassets, tetras, small catfish, barbs. But small shrimp will be happy to eat even dwarf cichlids. Males apistogramm in a small aquarium will be aggressive to each other, so you can keep a couple or a harem.

Another popular type of aquarium fish is the scalar. These fish are also thermophilic, do not destroy plants. But they will eat up all the small neighbors (neon, rasbor), and the aggressive fish will cut off their beautiful long fins (crests, denison, many types of barbs). For these reasons, the list of neighbors is small - unhurried gourami, mollies, petilles, cherry barbs, some soma.

The kings of the freshwater aquarium - the discus - are very demanding to the conditions and nutrition of the fish. In addition, the preferred high temperature - 28-31 ° C. Far from all plants and animals can withstand such heat. They are compatible with discus: catfish tarakatum, clown combat, Ramirezi's apistogram, red-bearing tetra, red neons. Discus gentle fish, prone to stress and various diseases, so it is better to abandon any neighbors.

As for other types of cichlids, such as the parrot, handsome chromis, labidochromis ellou, black-striped cichlid, astronotus and others, it is difficult to pick up the neighbors. These fish are territorial, aggressive, they need shelter. They dig the ground, pull out all the plants. Two males in a small volume will constantly conflict, so you can keep them in pairs or harems, with other active fish, able to stand up for themselves. They are compatible only with other cichlids, and because of intraspecific aggression, it is better to choose neighbors with a different color.


That viviparous most often become the first pets beginners. Sword-bearers, mollies, platies, aquarium guppy fish. All types of viviparous are unpretentious in content, not aggressive, easily get along with other types of peaceful fish. In addition, a huge number of varieties and colors viviparous. More than 80 species of guppies, dozens of species of placiums, mollies, swordtails differ not only in coloring, but also in the shape of the body and fins.

Of course, in the content of viviparous there are some subtleties. Males of swordtails can be aggressive, therefore they do not recommend settling several males in one aquarium. And guppies can provoke barbs, thorns, angelfish, some gourams with their bright long tails.

Guppies - the smallest of viviparous, but larger molly, placium and swordfish can be settled with scalars, gourami, barbs. Neon, rasbora, cardinals, tarakatum, speckled catfish, corridors will be good neighbors for all.


Suitable for beginners and labyrinth aquarium fish. Species of these fish are remarkable in that they need atmospheric air for breathing. Some labyrinths are pretty jumping, so the aquarium should be covered with a lid, but with an obligatory gap. In the aquarium should be a lot of plants and shelters.

Males of males and macropods are very aggressive towards other males of their own species, therefore they need to be maintained by a harem. Conflicts between males will be with gourami, lyalius. They need a spacious aquarium and several females. All types of labyrinth females also need shelter in order to hide from harassment during spawning.

Despite the intraspecific aggression, the labyrinths get along well with other peaceful fish - swordtails, petillia, mollies, neons, rassets, zebrafish, cherry barbs, antsistrus, cardinals, speckled catfish. You can not settle with fish that love to tear off fins - barbs and ternitsemi.


It is not easy even to list all the types and names of aquarium fish of the Haracin family. They are quite different from each other - this is the well-known neon, tetra, and Khujet's rare pikes, predatory piranhas, flying blazer-belly, and huge black pacu.

Tetras, phantoms, congos, ternas are very active, peaceful fish of medium and small size. They live in flocks, so do not purchase less than 7-10 individuals. Black neighbors, tarakatums, lyalius, speckled catfish, danios, cardinals, viviparous can be neighbors for them. Some tetras like to tear off other fins to other fish, so they need to be carefully kept with their tail fin.

Black, red and blue neons are peaceful little fishes. They need to settle with a flock of 15 individuals. Because of their small size, large fish are dangerous for neons, it is better to give preference to smaller and non-predatory neighbors - rasboram, small haratsinovym, apistogramma, clipped belly, viviparous, cardinals, iris, barbs.


Botsiya-clown, tiger and marble combat - large and very active fish. They prefer to live in a flock of 5 individuals. Get along well with other peaceful fish of medium and large sizes. They can tear off the veil fins. They eat plants and snails.

Botsi stay mostly at the bottom, occasionally rising in the middle layers of water. Therefore, it is better to supplement their company with fish that live in the upper layers. Good neighbors for fighting can be barbs, angelfish, danios, gourami, viviparous, rasbor, iris, labo, tetra.


Cherry barb is the most peaceful type of aquarium fish among its relatives. It will easily get along with small fish, but large and predatory neighbors can easily offend him. They contain a barb by a flock of 5 individuals, in the company of neons, rasbor, cardinals, danios, corridors.

As for the other types of barbs - Sumatran, fire, mutants, they are known as hooligans and bullies. Active fish that will not be offended will approach them as neighbors - danio rerio, ternets, congas, tetras, tarakatums, speckled catfish, cardinals. Fish that have long fins that will annoy barbecues - goslings, hyalus, will not work.


Danio - active small aquarium fish. Compatibility of species - the table shows that due to its size and peaceful nature, danios get along well with many fish. To keep them you need flocks of at least 5 individuals.

The list of good neighbors for danios is really extensive - viviparous, cockerels, angelfish, gourami, fighters, iris, rasbor, labo, tetra. All peaceful fish of small and medium size, which will not offend danios, are suitable.


Labo bicolor is often recommended as a calm fish for a common aquarium. But it is not. The young labo will be shy and shy, but an adult will begin to protect its territory and attack fish that resemble their relatives. Several laboos will invariably conflict. Fast fish that live in the upper layers of water - danios, thorns, barbs, can live with him. Green Labo will also be able to temper his aggressiveness if he has his own territory and shelter, which he will defend.

It occurs in our zoomagin and black labo. This fish does not tolerate their relatives, aggressive and territorial. It grows up to 80 cm in length and needs a large volume aquarium. It can live with large fish, for example, with the red-tailed catfish. But conflicts are not excluded.


Another pets for beginners - goldfish. Aquarium species of these fish are very common. If you look at the compatibility table, the line devoted to goldfish will be completely filled with red, with a few yellow areas, just like many cichlids. But if cichlids are aggressive, then goldfish often become victims themselves. Goldfish are large, and little things like rasbor and neon, they gradually eat. And the other inhabitants of the aquarium themselves can offend the slow and delicate little crowns with long fins.

Golden fish is best to settle with their own kind, there are enough interesting varieties of this breed. It should not be forgotten that if you want to get offspring, then you cannot keep different species together. Who do goldfish can get along with? Aquarium species of calm catfish - the Tarakatum, fighting-clowns, corridors, peaceful tetras - Congas, terntions and calm danios will be fine. There are also examples of successful cohabitation of gold with neons, scalars, viviparous, but we must remember that any neighborhood of goldfish with other species may result in conflicts and death of the inhabitants of the aquarium.


The bottom is occupied by aquarium fish - catfish. Types of catfish are very diverse, they differ both in size and behavior. Consider the most common.

Shy platydoras will surely eat all the fish that fit into his mouth. Therefore, it can only be maintained with large fish, for example, cichlids.

Most often in an aquarium live ancistrus. Several antsistrusov can be kept only under the condition of a large aquarium, these fish are territorial. But to other species they are not aggressive, and very few people touch them either.

The corridors are another popular catfish species. They are kept in a group of at least 3 individuals, if they are eaten by space - 10-15. Fish are peaceful, but their large fish can eat. Ideal neighbors for corridors are tetras, rasbaras, danios, viviparins, dwarf cichlids. They do not like water with a temperature above 25 degrees, so it is not suitable for content with thermophilic species.

Tarakatum has a peace-loving nature and can coexist with peaceful fish and even with other catfish.

Red-tailed catfish can often be seen in pet stores, but this fish is not suitable for a common aquarium, as it grows very large - up to a meter, and simply eat all the inhabitants. It can live with commensurate fish, but the aquarium for a group of such large fish must be very large - from 1000 liters.

Glass catfish is well suited for a general aquarium, it can live with commensurate and small fish - neon, ramming, small gurus, Ramirezi apistogram, catfish. Large fish are dangerous for this peaceful catfish.

Pterigoplichts grow large, so neighbors must be matched - large cichlids, giant gourami, fish knives, polypteruses.

Aquarium fish: species compatibility

In the maintenance and breeding of aquarium fish has its own special nuances and nuances. This should know everyone who is going to get a new "pets" - aquarium fish. Knowledge of what ornamental fish eat will not be enough. A huge role in the content of these creatures plays the compatibility of their species.

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

Compatibility of aquarium fish in their habitat

This is perhaps one of the most important aspects of proper and healthy keeping fish at home. It is important to know that not all fish can exist only in brackish water or only in fresh water, but most of them still prefer fresh water: goldfish, guppies, roosters, pink danios, etc. By the way, here we should also include a certain temperature regime, which is optimal for certain fish.

Compatibility of aquarium fish by their temperament

This is another important criterion for friendly neighborhood. In no case can not keep in one aquarium fighters and peaceful fish. Otherwise, the former will simply destroy the latter. For example, Siamese fighting fish (or cockerels) are fighters from nature. If they start fierce battles between themselves, then about their neighborhood with calm species of fish in general and there can be no talk! It is curious that in one aquarium it is not even recommended to keep two male males, since one of them will surely die in a fierce fight.

Compatibility of aquarium fish: predators - a threat to peaceful fish!

Predatory fish - not neighbors peaceful! The fact is that these species prefer to eat live food, so they can easily be attacked by those fish that eat dried insect larvae, plankton, etc. The only case when predatory fish do not attack the peaceful ones is the large size of the latter. But it is worth the predator himself to grow in size, as he immediately prefers to eat his peaceful neighbors. In this case, you need to either separate the aquarium with opaque glass, or arrange the fish in separate tanks.

Compatibility of aquarium fish in their sizes

It is not recommended to place small and large kinds of fish in one aquarium. In this case, the fish will begin to experience significant discomfort. In addition, the difference in their size will constantly affect the amount of food eaten by various species of fish: the tiny inhabitants of the aquarium will always get only the crumbs, while large fish will eat large tidbits. This rule should be followed when there is a need for breeding fish of the same species: if possible, only individuals of approximately the same age and size should be kept together.
Experienced aquarists say that it is best to breed small and gregarious fish. The fact is that these little fishes are unpretentious, very beautiful, and also affordable. They do not require much effort and cost in their care. The most striking among them are the following fish: guppies, barbs, striped danios, picnic, swordtails, mollies. However, even here there is a rule: fry should be kept separately from the adult generation. In the aquarium to adult individuals, they should be released when they grow up.
