Types of labyrinth fish for home aquarium

Labyrinth fish (lat. Anabantoidei), or creep-shaped, are ray-finned representatives of the Perciformes order who can capture atmospheric air using a special labyrinth organ. Many of these fish live in Asia and Africa, differ in a number of qualities, such as the difference in behavior and appearance.

Labyrinth fish are divided into species, some of them have long been known within our country. The most popular are the so-called "gourami", lyalius, cockerels, macropods. These are aquarium species that do not have difficulty in maintenance and care. They are bred both by amateurs and experienced aquarists, almost every year new types of labyrinth fish appear, of different colors, sizes and shapes. The suborder “labyrinth fishes” were called so because of a special organ that allows the fish to jump out of the water, inhale the atmospheric air, and, thanks to the channels, spit it out with the water.

Inhaled air enters the labyrinth channel, saturating the blood with oxygen. Some species become accustomed to living in water that is little saturated with oxygen: for example, experienced amateurs risk taking the macropod with them on the road, wrapping it in a clean, damp cloth. For labyrinth fish, aquarium aeration is not necessary, however, like all pets, they leave behind waste.

Famous representatives of the labyrinth, aquarium species

Common representatives of this sub-order in our country:

  1. Cockerels - breeding forms (crown-tailed, veil, short-tailed, half moon); Betta splendens, B. Coccina, B. Rubra, B. Falx, B. Imbellis.

    Look at the types of cockerels.

  2. Fish gourami - a group with numerous representatives. True gourami are rare aquarium fish Osphronemus Goramo and Holostoma Temminckii. Also there is a striped colise, trichoaster (pearl, brown, spotted, moon). Gourami of the genus Colise are four common types of fish: honey colise, lyalius, lyabiosis. Rarely found in home aquariums striped colise.
  3. Small fish classic colors - gourami Trichopsis genus (Dwarf gourami and Grumbling gourami). Less common is the subfamily Spherichtinovye - types of chocolate gourami. Also in some nurseries are found parosfromenusy.
  4. Group Macropods - no different variety, like gourami. Macropod Macropod Macropodus Opercularis is the most common striped, blue, red, albino color. Also popular are black macropods (concolors), macropods rotruken, Chinese macropods. It is also necessary to attribute Pseudofromenuses to the Macropoda group — the polyacanthus of the Day and the polyacanthus kupanus, the malypulata of the cretseri.

General characteristics

Representatives of the Labyrinth suborder have common biological characteristics, the main of which is a labyrinth organ, due to which they adapt to life in reservoirs with low oxygen content. This formation is located above the gills, the organ consists of thin plates. The organ has many blood capillaries where gas exchange occurs.

However, not all aquarium fish of this suborder use the organ for its intended purpose. For example, lyalius can live for a long time without air, unlike the trichogaster. The frequency of oxygen capture by fish depends on the state of the reservoir and the presence of oxygen in it.


Almost all representatives of the labyrinth fish have common morphological characteristics: an oblong body with flattened sides, a small head with a small mouth, long fins on the back. Everyone's body color is different, in the dark they look more spectacular. Males have a brighter color than females. During the spawning period, the color of the fish changes, becoming richer. The pectoral fins are filiform, the anal fins are long. Threadlike fins help to find objects in the water.

Content of creepy fish

For a flock of small cockerels fit a tank with a volume of 20 liters, for large gourami an aquarium of 200 liters is needed. They prefer soft and sour water, they refuse to give offspring in hard water. Sensitive to nitrates and ammonia. The presence of overgrowth is welcome, floating plants (vodokras, pistia, Riccia) love. The soil should be clean and natural in diameter to 3-4 mm.

Watch a video on the content of the macrozopod labyrinth fish.

As decorations can be used aquarium snags, coconuts, clay pots. Do not tolerate bright lighting, feel comfortable in soft and dark light. The water temperature should be 23-25 ​​degrees, powerful filtration and aeration is not required.

Breeding features

Each group of labyrinth fish prepare for spawning in different ways. Some aquarium inhabitants build a nest (macropods, trichogasters, some males and trichopsis), others build some sort of nest of foam and plant residues, enveloping the formation of saliva and air bubbles. Nests are often built by males. Parosfromenuses, malpylatus and pseudofromenus "mold" nests in cave houses using foam.


Labyrinth fish Kissing gourami form a nest, releasing a spot of oil on the surface of a reservoir that carries the function of a nest. Chocolate gourami and some cockerels carry caviar in the mouth. After the spawning, the fish anabas and ctenopomes do not protect the offspring, it floats defenselessly on the surface of the water.

Labyrinth fish for your aquarium

Labyrinth or creeping fishes of the perciformes suborder are predominantly freshwater and live in the countries of Africa and Asia. The labyrinth family includes more than 30 species of fish, which are distinguished by an individual feature of the body structure having a labyrinth organ. With the help of this body, fish additionally breathe atmospheric air and can live even in dirty reservoirs with insufficient amount of oxygen.

Cockerel Fish

External description

Macropod

Almost all labyrinth fish have similar external features. Have an oblong body, flattened on the sides. Head and mouth small, dorsal and anal fins long. In the nadzhabernoy cavity there is a labyrinth organ with a complex system of structure. Thanks to this organ, fish can live for some time even outside the water in a humid environment. While in an aquarium, fish swim to the surface, swallow air and use oxygen for breathing.

Labyrinth fish have an interesting body color and effectively look on a dark background. Males are brighter, during the breeding season, their color only enhances their hue. Also have a distinctive feature associated with the pectoral fins, which are formed filamentary form. Their fish are used as organs of touch and feel objects with the help of them.

Varieties

There is a huge variety of representatives of the labyrinth family, many fish are popular and enjoy wide success among aquarists. The most common are considered to be cockerels, gourami, macropods, and lyalius. All species are divided into groups depending on the method and place of eating. Fish of the genus Trichogaster take food from the surface of the water, and the rest of the labyrinth fish grab the food in separate pieces from the bottom or from the ground.

Cockerels

Aquarium cockerels are known for their pugnacious behavior. The intensity of the color of the fins of males usually determine the strength of their aggression. But the fish show their anger mainly among their male relatives, especially during the spawning period, when females are deposited.

The color of the cockerels depends on the species of crossed fish, an interesting coloring of the offspring can be achieved by crossing fish of different colors. Males live up to 3 years in good conditions.

Gourami

Pearl gourami

These aquarium fishes have the most numerous species, pearl, moon, spotty, grumbling and brown gourami are considered popular. All aquarium species, except the spotted ones, have a peaceful character, can be up to 15 cm in length.

Gourami unpretentious care, but not averse to eat plants in the aquarium. Spawning occurs in a separate tank, each species in its own way. Some spawn in a foam nest, others carry eggs in their mouths. Aquarium should be closed with a lid due to their jumping ability.

Macropods

Macropods are colored greenish-lilac with orange stripes. These fish are remarkable for their fecundity, when the female is able to lay up to 800 eggs for one litter. The character resembles aggressive cockerels, so the joint content of two males in the same container can lead to conflicts. There are such types of macropods as ordinary black, red spine.

Lyalius

Aquarium liliusi reach up to 6 cm in length and have a bright green-bluish color with red spots on the fins. These fish are very shy, so you need to keep them a flock and sit down to them peaceful middle-sized neighbors. Lyalius prefers bright lighting and loves to hide in dense thickets of plants or shelters.

Betta pict

Betta pict fish are colored in brown with golden breast and longitudinal stripes. Males are more peaceful, and females protect their territoriality. Sexual maturity reaches 10 months; males incubate eggs in the mouth.

Labiosis

This fish is also called the “spongy colise”; it looks like a lyalius. In an aquarium it reaches 8 cm in length, its body is high and oval. In females, the dorsal fin is rounded, and in the male, it is pointed. They have a gray-greenish color with a violet front and a blue back. The tail has a dark speck. There are also red and red-striped types of labiosis.

Betta pict

Content in an aquarium

The size of the labyrinth aquarium is chosen depending on the number of fish inhabiting it. For a flock of roosters fit capacity of 20 liters, and for a couple of larger gourami need an aquarium of 100 liters.

Water changes should be carried out in a regular manner and the content of nitrates and ammonia in the water should be monitored. Water is needed soft and sour, in hard water the fish are unlikely to want to breed.

Labyrinth fish are very fond of plants, so there should be a lot of them in the aquarium. To do this, select the correct natural soil with a diameter of 3-4 mm. It is important the presence of floating plants such as pistii, Riccia and vodokras. These plants can also support the nest. The scenery can serve as an interior solution, as well as a place for fish shelters. The most profitable fish will look on the background of coagulums, coconut shells, clay pots. Also the dark background will be optimal, with a light design the fish will feel unprotected.

For labyrinth fish, the presence of a compressor and a powerful filter is not important, the optimum temperature is 23-26 ° C.

Feeding

Lyalius

It is not recommended to use special feeders for fish, since it is fraught with obesity for the most arrogant fish, and malnutrition for the most shy. It is best to scatter food over the surface of the water over the entire area of ​​the aquarium. Feed should be different, but suitable size.

Of the feeds, live and frozen cyclops are preferred, contributing to the enhancement of the color of fish, as well as bloodworms, koretra, daphnia, and shredded seafood. In addition, microworms, greenal, earthworms, enkhitrei will do. Dry food should be of high quality, optimal flakes. Additionally, you can feed with freeze-dried or gelled feed.

Compatibility

Labyrinth fish are quite peaceful, with the exception of some species. In the neighbors they should choose peaceful and non-predatory fish. Gourami get along well with macropods, lalius and short-tailed cockerels, as they can damage the veil fins. From other families, suitable species are haracin, discus, soma, neon, angelfish, apistograms, danios.

It is not recommended to plant labyrinths with cichlids such as pseudo-trophy and labidochromis, as well as with goldfish.

Labiosis

Breeding

The breeding process of the labyrinth fish can occur in a common or separate aquarium. It is best to breed them in spawning, as in the general aquarium they are unlikely to be able to feed all their offspring.

For 2-3 weeks, manufacturers are deposited in different places and fed with bloodworms, which will serve as prevention of cannibalism. Fishes make their nest very nicely by blowing air bubbles to the surface of the water. The male is actively caring for the partner, and the female hides from him. Then the female swims and they whirl together in the nest. After spawning, the female should be removed, and the male takes care of the calf. The parent will independently add air bubbles to the eggs. When the fry swim, the father must be removed so that he does not harm the fry, which can be fed with living dust and infusoria.

Aquarium fish of the labyrinth family are the favorites of many aquarists due to their unpretentious care, bright appearance and ability to adapt to different conditions. Proper combination with neighbors and good content will be the key to their long and healthy life in the aquarium.

Labyrinth fish

A variety of labyrinth aquarium fish is huge. Many of them are quite popular among aquarists. At the same time, new or long-disappeared species from aquariums are constantly appearing on the market: lyabiosis, trichopsis, new forms of Siamese cockerels. Three representatives of the species can be distinguished from the most common labyrinth species: cockerels, gourami, and macropods.

These fish got their common name due to a special labyrinth organ that allows them to live in water bodies with insufficient oxygen: in Chinese rice fields and even in dirty ditches.

A labyrinth organ is a nadzhabernoe formation, which consists of thin plates. There are many blood capillaries in it, which provide the missing gas exchange.

Original and breeding labyrinth fish. Many of them build a nest on the surface of the water from air bubbles, which the male holds together with its saliva. Some in their construction include the remains of plants.

Cockerels

cockerel fish

Their many species and breeding forms, which are quite different. All male cockerels are known for their pugnacious temper. And they were really used for fish fights. And it is the males that have a brighter color of fins, similar to a veil. And the angrier the cockerel, the brighter his fin.

Homeland of cockerels - Indonesia. In the aquarium, cockerels fight when they are spawned from females before spawning, and when the nest is settled, all the fish are distilled.

But for spawning, not the brightest, but the largest and youngest (7-9 months) males are selected.

To stimulate the reproduction of labyrinth fish, you need a special aquarium for spawning with a capacity of about 10 liters. In it, the water should have a temperature of 27-28 degrees. It will take a bunch of Riccia, which the rooster used to build a nest.

In the breeding ground, the male and female are fed live food. After the construction of the nest steam begins to spawn. At the same time she goes to the bottom, and the male picks up the eggs with her mouth and puts them into the nest. After that, the female is deposited, and the male remains to monitor the offspring. It is separated only after the fry swim independently.

The life span of males reaches three years. Their color depends on the crossed fish. In monochrome fish and the offspring will be so, and if you select to spawn colorful fish, you get a mixture of colors.

The roosters eat both dry and live food. Often they are used as cleaners for the aquarium, where too many snails bred. Males quickly cope with this overpopulation.

Gourami

pearl gourami

This is the most numerous labyrinth aquarium fish. Although their name is not quite right. This gourami is too large for an aquarium, and these fish belong to the genus Trichogaster, there are only four species in it: lunar, brown, spotted and pearl.

The largest of them is brown gourami, reaching a length of 15 cm. But the fish is peaceful.

The main color of this fish is brown with a black longitudinal stripe. The male is larger and brighter than the female.

Lunar gourami slightly smaller. It is silver with a blue tint. Males also have pelvic fins of red-orange color.

These fish love to eat soft aquarium plants.

Spotted gourami have many color morphs: blue, purple, marble, blue-red, yellow, white, pearl.

They grow up to 12 cm. Females are more pale and with a rounded abdomen.

Pearl gourami on a gray-lilac body has pearly specks.

Gourami differ and a variety of characters. There are both peaceful and aggressive, especially the spotted look.

Features content gourami

An aquarium for labyrinth fish of the genus Trichogaster is needed for not less than 50 liters, and for the lunar and brown for more than 110 liters.

All labyrinth fish do not need a compressor. Optional filter. Although if the aquarium is large and there are many inhabitants in it, it is better to install a filter, but direct it to the wall so that the flow does not interfere with the construction of foam nests. Moon and spotted gourami can build them even in the general aquarium.

If the labyrinth fish in the general aquarium do not breed, a cyst may form in females of not spawned eggs, which will result in the death of the fish. Therefore, if the female constantly swims with a thick belly, then she and the male should be transplanted into a separate aquarium to spawn.

Оптимальная температура воды - 22 - 26 градусов, а в нерестовнике она должна быть выше на 2 - 3 градуса.

Лабиринтовые нерестятся по-разному. Одни, как и петушки, строят пузырьковые, целующиеся гурами на поверхность воды выпускают маслянистое пятно, которое становится гнездом. Chocolate gourami are carrying caviar in their mouths.

These fish do not spoil the plants, so the labyrinth fish tank can be thickly planted with plants. Be sure to have either floating plants (duckweed, pistii, riccia, salvinia, etc.), or floating leaves of vallesneria or nymphae. The soil should be made dark, with snags.

Since gourami do not jump badly, the aquarium should be closed. Best of all they feel in slightly acidic and slightly soft water. All kinds of macropods and lyalius will approach them as neighbors. And of the roosters, it is better to share only the short-tailed. Gourami can eat long fins of neighbors.

Other families of fish can be hooked to gourami: neon, scalar, catfish, apistogram.

Macropods

macropods

This group is less diverse. Its representatives have greenish scales and dirty orange transverse stripes. The male has longer fins, and the tail ends with thin filiform processes.

It is paradoxical that in nature this creature survives at 10-12 degrees of heat, but they prefer water at 23 - 25 degrees.

It is very easy to breed macropods, as they are surprisingly fertile - there can be up to 800 fry in one litter.

They multiply in the same way as many labyrinths - building nests of air bubbles. During this period, the males become aggressive, driving away all the fish from their nests.

Lyalius

lyalius

This is another small type of labyrinth fish. It is a small but bright fish up to 6 cm in length. Its color is greenish-blue with transverse stripes of blue-blue and red, near the gill. Fins are covered with red spots.

Lyaliuses are very shy and they need calm neighbors. From fright, Lyalius often climbs to such places in an aquarium where he cannot escape from on his own and perishes. It is better to keep them in flocks, then they become less fearful.

Lyalius prefer bright lighting and thick algae. They need a small aquarium up to 10 liters with not very warm water - 18-20 degrees.

They feed on lilyusi live food: daphnia, cyclops, small bloodworms, eat small dry food.

This fish is bred easily enough, but in warm water about 30 degrees. The male builds a nest of bubbles on the algae frame. After spawning eggs, the female is deposited, and the male cares for the offspring. It is removed from the aquarium on the fourth day, when the fry are just beginning to swim.

Labyrinth fish

About 20 species of fish that inhabit our aquariums belong to the labyrinth family. They are distinguished not only by their beauty and brightness, but also by their behavior.

Labyrinth fish got this name because of a special organ - a labyrinth, in which the circulatory system is saturated with oxygen directly from atmospheric air. Thanks to this apparatus, they can live in water that is little saturated with oxygen and has been on land for quite a long time. Fish often swim up to the surface and swallow air, so they are forbidden to be transported in closed containers filled to the top with water, this leads to their death.

Family Labyrinth

The second is the scientific name of these fish Anabasic. They are divided into species: macropods, gourami, cockerels and anabass. There are about one hundred representatives of this species.

The labyrinth family includes fish with an oblong and compressed body. They have a short head and a small mouth, the dorsal and anal fins are rather long. The labyrinth organ is located in the supracavitary adnexal cavity.

Representatives of this family are insensitive to the purity and freshness of water. They are able to live in cramped reservoirs with ruined, muddy water. But this feature does not apply to fry, as the labyrinth organ only develops up to 3-4 weeks of age, and during this period they are also sensitive to the purity of the reservoir.

Types of labyrinth fish

The hardiest, of all the anabasic, are macropods, they are able to live even in spoiled water, and are not picky about the cold. They are not recommended to be kept in the pond with other fish; over the years, the macropods become very pugnacious, especially during the spawning period. The maximum size of a macro can be up to 12.5 cm.

The most common type of anabasic are certainly gourami. They are most suitable for multi-species aquariums. Their size is on average 10-15 cm. Adults with gourami sometimes attack small inhabitants of an aquarium, and they have to be relegated to larger fish.

One of the most colorful types of labyrinth fish are cockerels. They are very beautiful, but pugnacious. Their name is a cockerel due to their liking, in a society with other males, they always, like real roosters, fight among themselves. They both inflate their gill covers and sticking them out in the form of a collar. Being in such an excited state, cockerels take on a very bright color.

The main colors of this type of labyrinth fish are blue, red, green or pink with oblong brown stripes along the whole body.

Such species as anabas is very famous, but, unfortunately, it is rarely found in aquariums. For them in the aquarium, it is desirable to acquire a lot of dense vegetation and koryag, so it will be more convenient for them to divide the territory in order to avoid conflicts.

Reproduction of the labyrinth fish

The spawning process of these fish is very interesting. During spawning, the males squeeze out eggs from the female, firmly “hugging” her. Then carefully collect the eggs and place them in their nest of air bubbles. In labyrinth fish males care for caviar, the female is able to eat eggs unnoticed by father, therefore he cruelly expels her.

Labyrinth fish in aquamire

Given the ability of these fish to jump over the water, they need an aquarium with a lid. Since anabasovye love to hide, hide, they need a large number of all sorts of plants, logs and stones. With regard to the compressor and the flow of water - it is not necessary, labyrinth fish can breathe themselves, and they do not like excessive noise. But the presence of light and heat they need. The food for these fish is dry or frozen food, bloodworm, artemia, coretira, daphnia, micro-crab. Feeders set is not recommended.

Labyrinth aquarium fish

The appearance of the labyrinth fish, especially the content, compatibility, feeding, breeding, caring for fry. Important information that will help you in the care of your pets.

The labyrinth family includes 18 genera and over 20 species of fish, whose habitats are the water bodies of South and Central Africa, as well as South and Southeast Asia. Their main difference is the adaptability to breathing atmospheric air. In addition to the gills, the fish of this family have a special organ - a labyrinth, which is a pocket-like outgrowth in the bones of the gill covers. Its folded walls are riddled with small blood vessels.

Appearance

Many have fallen in love with these attractive representatives of the aquarium for their beautiful color, original body structure, smoothness and unhurried movements. Labyrinth fish have a graceful oblong body flattened on the sides, a short head, a small mouth, a long anal, dorsal and tail fins. Pelvic fins elongated, filiform. Males have a brighter color, which only increases during the breeding season.

Features of the content in the aquarium

Keeping a labyrinth in an aquarium is easy. They do not need aeration systems, like other representatives of chord. To reduce the difference in temperature of the water surface and the air layer above it, as well as to exclude the possibility of jumping fish from the aquarium, it is better to immediately buy an aquarium with a lid. The volume of the dwelling is selected based on the number of fish inhabiting it. For soil, you can use gravel or coarse river sand with a diameter of 3-4 mm.

Labyrinth fish feel more protected against a dark background among the dense thickets of living plants, which delimit the territory into zones. Here, a weaker fish can escape from the pursuit of more aggressive fish. A good refuge for labyrinth fish can be branches and snags, cave-type shelters made of stones.

From plants it is better to choose those that grow quickly and spread over the surface. For example, valisneria. Building materials for the future nests are floating plants (Riccia, Vodokras and others).

Keep these fish to acidic and soft water or in water with medium hardness. The temperature for them is suitable in the range of 23-26 ° C. Substitutions generally do no more than once every two weeks. They change one fourth of the volume of the aquarium with distilled water. A filtration system can be used to remove suspended particles and mix the temperature layers. But since the fish do not like a strong current, it is better to wear a flute at the exit of the filter. The compressor is needed only for growing fry; in the first three weeks they form a labyrinth machine.


Compatibility

Basically, all labyrinth fishes are quite peaceful. Can calm to live next door with small characteristic fish, mollies, swordtails, with almost all catfish. Get along not with all the barbs don't get along completely with anabasas, macropods, cockerels. By small labyrinth guppy can be hooked. Pelvicahromis and apistograms get along with almost all labyrinths.

Feeding

When feeding the labyrinth there is no difficulty. Fish feed both live and dry food. Preference is given to animal feed. To have enough food for everyone, you should not use special feeders. It is best to pour food over the entire surface of the water. For fast and healthy growth fish need a balanced diet. You can enhance the color with the help of frozen or live Cyclops, bloodworms, daphnia, shredded seafood. Dry food should be of good quality.

Breeding

Before breeding, the male and female are seated in separate tanks or aquariums and are fed abundantly with bloodworms for 10-14 days. Introduction to the diet of Daphnia, Cyclops can lead to eating offspring.

To stimulate spawning, water is replaced by a soft one and increased by 3-5 ° C. When the female’s abdomen is noticeably rounded, she and the male are transplanted to the breeding ground. At the sight of a female, the usual slowness and sluggishness of the male disappears, he begins to chase her quickly. This lasts from several minutes to several hours.

After sailing, the male rises to the surface and starts building a nest. Having seized air bubbles with its mouth (often with debris of Riccia), the male spits them out, creating an even circle. When the circle reaches 4 cm, the male begins to finish building the middle, gradually creating a cap of air bubbles above the surface.

If the riches are many, then the nest resembles a hat, which rises 2.5-3 cm above the water. If it is small, the nest is wide and flat. The construction takes several days. When the nest is ready, the female swims up to it and begins to spawn. The man fertilizes the eggs.

Spawning can last up to several hours. Depending on the type and individual characteristics in the litter can be from 50 to 800 eggs. The harvested eggs of the male, and sometimes both fish, grab into the mouth and spit into the foam of the nest. To avoid persecution by the male, it is better to lay the female after spawning.

Fry

The male takes all the care of the future offspring. He collects accidentally dropped eggs from the nest and returns them back, discards non-viable. Constantly maintains the nest state. Somewhere in 6-7 days the larvae, turning into fry, begin to swim horizontally. Their swim bladder fills with air and they float out of the nest. To prevent the male from eating his own offspring, he needs to be transplanted.

Fry for 3-4 weeks need additional aeration of water. Until the labyrinth apparatus develops, they breathe in the gills. For rapid growth need abundant food.

Optimal fry food - ciliates, rotifers and other live dust. A little later, you can give Nauplii Artemia, sliced ​​tubule. Consolidation of feed should occur gradually. Therefore, larger feed should be thoroughly chopped.

Interesting

Some species of the labyrinth family do not build nests and do not care for caviar.

With cockerels, it is better not to plant swordtails and mollies (they can cut off the fins of cockerels).

Due to the unusual appearance, unpretentiousness in care and an amazing ability to adapt to different environmental conditions, the labyrinth fish attracted attention and won the love of most aquarists. Proper maintenance, balanced food and a good combination with inconsiderate neighbors will be the key to a healthy and long life.

Content in an aquarium

The size of the labyrinth aquarium is chosen depending on the number of fish inhabiting it. For a flock of roosters fit capacity of 20 liters, and for a couple of larger gourami need an aquarium of 100 liters.

Water changes should be carried out in a regular manner and control the content of nitrates and ammonia in the water. Water is needed soft and sour, in hard water the fish are unlikely to want to breed.

The parent will independently add air bubbles to the eggs. When the fry swim, the father must be removed so that he does not harm the fry, which can be fed with living dust and infusoria.

What fish belong to the labyrinth in the game on Mail.Ru: Aquamir - 3D aquarium?

Dark Oracle

The labyrinth fish include freshwater fish in South and Southeast Asia, a small number of their species also live in Central and South America. Labyrinth fish are interesting in that, along with the gills, they also have an additional organ labyrinth - an outgrowth of gill arches in the form of rolled thinnest bony plates covered with a mucous membrane rich in vessels. This body allows them to live in muddy, warmed by the scorching rays of the tropical sun, small rivers, irrigation ditches and shallow water in the rice fields of their homeland. With the help of a maze, they capture oxygen directly from the atmosphere. Air breathing is necessary for them. If the aquarium is tightly covered with glass so that it touches water, the fish, deprived of air, will soon die, even if there is a lot of dissolved oxygen in the water. The ability of fish to capture air from the atmosphere allows you to keep them in the smallest aquariums. So, two small labyrinth fishes easily get along in a three-four-liter jar.
Warm plants should be planted in the labyrinth aquarium: Vallisieria, sagittarium, Ludwigia, and let a few Riccia swim to the surface of the water. It is better not to plant a kabomba, as the fish, constantly jumping out for new portions of air, break its fragile branches. From the plants in the labyrinth aquarium, the hornet and peristristum are very beautiful. A small aquarium should be closed with glass or gauze, otherwise the fish from it can easily jump out.
Labyrinths are very thermophilic, and their content requires water with a temperature not lower than 20 degrees, when breeding fish, it should not fall below 25-27 degrees. The higher the temperature of the water, the brighter colored fish and become more lively. The second interesting feature of the labyrinth fish is a kind of care for the offspring. During spawning, the male builds a foaming “nest” from the air bubbles on the surface of the water, in which the fry hatch. He also takes care of fry.
