Thirsty - fidget in a black skirt

Ternesia (Latin Gymnocorymbus ternetzi) is an unusual aquarium fish, which is well suited for beginners, as it is hardy, undemanding, and very easy to get divorced. Especially good ternation looks in the general aquarium, as it is active and mobile. However, it can pull the fins of other fish, so you should not keep it with veil forms or with fish that have long fins.

The common termination is a schooling fish and it feels good in the group. It is better to keep in a flock of 7 individuals, and the more there will be them, the better. Aquariums with dense vegetation, but also free places for swimming, are well suited for maintenance.
In addition to the classic version, now also ternation with veil fins, albinos and caramel are popular. The difference between the caramel termination and the classic one is that this fish is artificially painted in bright colors. However, all these morphs do not differ in content from the classical form. Only with caramels you need to be careful, after all, interference with nature significantly weakens the fish.

Habitat in nature

Ternesia was first described in 1895. Fish common and not listed in the Red Book. It lives in South America, home to the Paraguay and Guaporé rivers, where it inhabits the upper layers of the water, feeding on insects that have fallen on the water, aquatic insects and their larvae. These tetras prefer the slow waters of small rivers, streams, and tributaries, which are well shaded by the crowns of trees. At the moment, they are almost not exported, since most of the terntions are bred on farms.

Description

The ternation has a high and flat body. They grow up to 5.5 cm, and they start spawning already at a size of 4 cm. Life expectancy under good conditions is about 3-5 years.
The ternation is distinguished by two vertical black stripes running along its body and large dorsal and anal fins. Her anal card is a business card, as it resembles a skirt and very much highlights the termination among other fish. Adults become somewhat paler and turn grayish instead of black.

  • Other fashionable options are:

  • The veil of thorns, which was first bred in Europe. It is very often found on sale, it is no different in content from the classical form, but it is somewhat more difficult to breed because of intragenital crossing.
  • Albino, is less common, but again, no different except for coloring.
  • Caramel ternets are artificially colored colored fish, a fashionable trend in modern aquarism. They need to be kept with caution, as the chemistry in the blood has not made anyone healthier. Plus, they are massively imported from farms in Vietnam, and this is a long road and the risk of catching a particularly strong type of fish disease.

Difficulty in content

Ternetia is very unpretentious and well suited for novice aquarists. It adapts well, feeds on any feed. Suitable for general aquariums, provided that it will not be contained with fish having veil fins.

Feeding

Extremely unpretentious in feeding, thorns will eat all kinds of live, frozen or artificial feed. High-quality flakes can form the basis of nutrition, and in addition can be fed with any live or frozen feed, for example, bloodworms or artemia.

Content in an aquarium

Since the termination is a very active fish, you need to keep them in spacious aquariums, from 60 liters. They love soft and sour water, but during the breeding period they adapted to different conditions. Also prefer to have floating plants on the surface, and the light was dim. Do not forget to cover the aquarium, they jump well and can die.
They look perfect in an aquarium with a natural biotope. The sandy bottom, an abundance of koryag and fallen leaves at the bottom, which make the water brownish and acidic.
Aquarium care is standard for all fish. Weekly water changes, up to 25% and filter availability. Water parameters may be different, but preferred: water temperature 22-36C, ph: 5.8-8.5, 5 ° to 20 ° dH.

Aquarium Compatibility

Thorns are very active and can be semi-aggressive, cutting off fins to fish. This behavior can be reduced by keeping them in a flock, then they focus more on their fellow tribesmen. But everything, with fish like cockerel or angelfish, is better not to hold them. Good neighbors will be viviparous, danios, cardinals, black neons and other medium-sized and active fish.

Gender differences

You can distinguish a male from a female by fins. In males, the dorsal fin is longer and pointed. And the females are fuller and their anal fin skirt is much wider.

Breeding and breeding

Breeding begins with the selection of a couple aged and active. Younger couples may also spawn, but efficacy is higher in mature individuals. Selected couple seated and richly fed with live food.

Spawning from 30 liters, with very soft and sour water (4 dGH and less), dark soil and small-leaved plants. Light is necessarily dim, very diffused or twilight. If the aquarium is heavily lit, cover the front glass with a sheet of paper.

Spawning begins in the morning. The female lays several hundred sticky eggs on the plants and decor. As soon as spawning is over, the pair needs to be transplanted, as they can eat caviar and fry. It is easy to feed fry, for this purpose any small feeds for fry will be suitable.

Aquatic ternation: maintenance and care, photo

Thorns is a popular aquarium fish. It is beautiful, durable and undemanding, and therefore suitable for beginners. Fish are often recommended to be settled in a common aquarium. But does termination get along with everyone? Maintenance and care, nutrition, breeding, compatibility - in this article you will learn all about this fish.

general information

Aquarium terntions are schooling fish and must live in a group of seven individuals. They love thick thickets of plants, but there should be free space in the aquarium for swimming.

In nature, ternation live in small rivers, streams and tributaries in South America. They inhabit the upper layers of water and feed on fallen insects. For sale the fish are bred on the farm. They live 3-5 years.

How large does the terns grow? The maintenance and care of this fish is simple, because it has a fairly modest size - up to 5.5 cm. These crumbs look very impressive in an aquarium. Body diamond-shaped, flattened laterally. There are two black stripes along the body, the anal and dorsal fins are large. The black anal fin in females resembles an elegant skirt.

Kinds

There are several types of terns: classical, voilean, albino and gold. Of particular interest is the product brand GloFish - genetically modified fluorescent fish.

These artificially bred pets have a bright color, which under the influence of ultraviolet light becomes even brighter. There are red, pink, blue, green, yellow and orange forms. Color is inherited.

Red color to the terntions is given by the red coral DNA fragments. They become green due to the presence of jellyfish DNA fragments. Yellow (orange) color gives a combination of jellyfish and coral genes. How beautiful is transgenic thorns? Photos show that such fish look, at least, unusual.

Recently, caramels have become popular - these are artificially colored fish. They can be bright pink, blue, green, orange.

Bright coloring is given by injection of the dye. Over time, it fades and becomes paler. Such fish are somewhat weaker and more vulnerable than their classic relatives. They live less and get sick more often. Coloring is not inherited. For a beginner, normal or genetically modified ternation will be more suitable.

Maintenance and care

Ternetsii unpretentious and undemanding fish. They don't need a huge aquarium. It is enough to adhere to a simple rule - about 10 liters of water should fall on one fish. That is, a school of 10-12 individuals will feel at ease in a 100-liter aquarium.

Comfortable water temperature - 22-24 degrees. The transgenic form needs a higher temperature - about 28 degrees. Hardness is not more than 18, the level of acidity is 6.5-7.5 pH. Since they prefer shady water in nature, plants should be planted in an aquarium to create natural shelters.

Filtration and aeration required. Every week you need to do a water change and cleaning the soil. In the aquarium there should be enough space for swimming, planting it too much is not necessary. On which background does termination look better? Photos show that the classic dark fish will look good on a background of light soil, and multi-colored - on a background of dark. The aquarium can be decorated with stones, snags, grottoes.

Character

What is the character of termination? The maintenance and care of fish depend on its temperament. As mentioned above, thorns are schooling fish. So, living in solitude brings them suffering. In the company of fish calm and peaceful. But, left alone, they become nervous and aggressive.

The flock can be kept with other types of fish. Ternets active, mobile fish. They can be divided into several groups and conflict with each other. In a spacious aquarium, they keep in the upper and middle layers of water, they float freely. In a small container, with overpopulation and stress, they hide in the thickets of plants, swimming only for food.

Nutrition

What dietary habits does ternation have? The fish is omnivorous and not prone to overeating. Ternetsia eagerly eat dry food, but especially love live and frozen food - daphnia, koretra, cyclop, artemia.

If you feed the fish with a small bloodworm, be sure to use the feeder. In nature, they seize insects in the upper and middle layers of water, so the mouth is anatomically arranged to raise food from the bottom simply uncomfortable.

Health and longevity of beauties largely depends on nutrition. It should be balanced and diverse. Do not feed the fish alone with flakes and granules. Be sure to include in the diet of live food.

Gender differences

Even an amateur can distinguish between sexes of ternets. The ternetia female is large, full, with a wide “skirt” of the anal fin. The male is smaller, slim, with a bright color. The tail fin has a white border, and the dorsal fin is longer, pointed.

Compatibility

By the nature of the ternation, they are considered to be peaceful fish, but this is true only if they live in a large flock and in an appropriately sized aquarium. Who can a ternsya get on with? Compatibility with peaceful fish - gouras, scalars, discus, lyalius, mollies, swordtails, guppies, neons, gambuzins, rasobrami, peaceful catfish.

It is impossible to keep in the same container with the tail cap, barbs, cichlids and other aggressive fish. Ternets will attack the slow-moving veils and tear off their fins. If ternations are contained in small groups (for example, only 2-3 individuals in an aquarium populated by other species) or in an overpopulated aquarium, they can become aggressive and literally start to terrorize other smaller and quieter fish.

Breeding

At 8 months of age, terntions that have reached a size of 3-5 cm are capable of reproduction. Smaller or larger fish are not allowed to breed. The spawning aquarium of 50 liters is filled with water at a level of 5 cm. Moss is put on the bottom. The temperature is set at the level of 24-26 degrees. Need a good aeration.

Three days later, one pair of producers is placed in the spawning tank. They need to be strongly fed with live food, preventing its remains from settling at the bottom. In 3-6 days spawning begins. The female will produce about 1000 eggs in small portions. After spawning, the parents are immediately removed.

The water temperature rises to 28 degrees. After a day the larvae come out, after 3 days they begin to swim. Juveniles feed lively dust. As the fry grows, they are sorted, since the terns are prone to cannibalism.

Thorns is a beautiful, bright and easy-to-care fish. Both classic and color form can decorate any aquarium. Even unusual glowing colored individuals do not require any special conditions and live long enough.

Plus, they are massively imported from farms in Vietnam, and this is a long road and the risk of catching a particularly strong type of fish disease.

    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.

    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.

    Aquarium Compatibility

    Ternetsii very active and can be semi-aggressive, cutting off fins to fish. This behavior can be reduced by keeping them in a flock, then they focus more on their fellow tribesmen. But everything, with fish like cockerel or angelfish, is better not to hold them. Good neighbors will be viviparous, danios, cardinals, mollies, black neons and other small and active small fish.

    Breeding and reproduction

    Breeding It starts with the choice of a couple aged and active. Younger couples may also spawn, but efficacy is higher in mature individuals. Selected couple are seated and richly fed with live food. Spawning from 30 liters, with very soft and sour water (4 dGH and less), dark soil and small-leaved plants.

The female lays several hundred sticky eggs on the plants and decor. As soon as spawning is over, the pair needs to be transplanted, as they can eat caviar and fry. It is easy to feed fry, for this purpose any small feeds for fry will be suitable.

    Behavior

    Temperament terration peaceful, which is not a hindrance to arrange attacks on each other, on smaller fish or with large fins. Hold on ternation at a medium depth free of plants. This is an indicator fish, the color changes depending on the environment or possible stress - from

    thorny

    almost transparent to intensely black. Because of the top location of the mouth, the fish feed on the surface of the water.

    What to feed terniy Food can be given to almost anyone. Live and frozen food, flakes, meat, bread crumbs will suit them. Eat mainly from the surface of the water, sometimes they catch food, slowly going to the bottom.

    TERNACE OF THE DISEASE

    Terrestitii are quite resistant to various diseases. In any aquarium, as a rule, various parasitic organisms are still present, but if good conditions are maintained, they are not capable of causing harm to the mourning tetra.

    In case of any deterioration of the living conditions, the ternation instantly reacts by changing the color and behavior. Good conditions of detention for terntions are a kind of basis for immunity, and constitute a complex of measures.

    The size of the aquarium should correspond to the number of ternine pairs, if there are several pairs, they will be comfortable in the aquarium at least 40 liters, densely planted with plants. Water temperature within 23 ° C - 26 ° C, water hardness from 5 ° to 17 °, pH 6.0 - 7.5.

    If these requirements are met, all that remains is to take measures to ensure that outsiders do not enter the aquarium into the aquarium.In this direction, the most effective way to protect is quarantine for new fish and plants for at least 3 weeks.

    You also need to be careful in purchasing live food, it is better to do it in certified stores. In this case, the termination of the disease can be avoided.

    • A shift in the pH of the water in the aquarium to 10-11 in bright sunlight and dense vegetation can cause the development of alkolosis (alkaline disease), a decrease in pH to 4-5 can provoke acidosis (acid disease).
    • In case of untimely removal of the waste products of fish from an aquarium, the concentration of ammonia in the water may increase, which in turn may cause the development of acetamia (ammonia poisoning).
    • In the case of overpopulation of the aquarium in the water may be reduced oxygen content, which will lead to the development of hypoxia (asphyxiation).
    • Regular overfeeding of terntions, the use of monotonous and low-quality food will lead to obesity and inflammation of the gastrointestinal tract.
    • Use for replacement of poorly separated tap water with chlorine will affect the development of fish chlorosis (chlorine poisoning).

    With the improvement of the conditions of maintenance, terntions can quickly restore their health. But it was during this period, when the defenses of the ternation were exhausted due to a violation of the normal conditions of detention, various parasites could be activated.

    This can cause the development of often incurable diseases: saprolegniosis, ichthyophonus, fin rot, ichthyophthiriosis, pellularis, plistophora, gluea, nodular disease, chylodonellosis, gyrodactylus, dactylogirus.

    Diseases and their causes

    Changes in water may also cause other diseases. Thus, for example, alkalosis occurs in Ternéti when the level of acidity shifts towards an alkaline medium. This can contribute to bright sunlight and excessive use of vegetation. But acidosis occurs when lowering the minimum threshold value in the range of comfort.

    If the content of Ternetium occurs irregularly, then there is a high risk of poisoning the fish with ammonia, the concentration of which becomes significantly higher from the waste products in the water.

    Ternations react very quickly to improved conditions. As soon as they are normalized, the pets' health is immediately restored.

Fish ternation: description, reproduction, care

Thorns is an unusual fish that is easy to keep in aquariums. It is unpretentious, agile, does not require special care, so it is ideal for those who are just starting to get animals at home. It is interesting to observe terrence because it does not sit still, constantly studying the filling of its house with water.

Description of the species

Ternesia is a well-known fish among aquarists. Thermal, with a peaceful character. Currently, its popularity, unfortunately, has declined slightly. This fish has a flat and high body, something resembling a rhombus, strongly flattened on both sides. Thorns can grow up to 6 cm in height in natural conditions, in aquariums, as a rule, they are smaller in size. They live with good care for about 4 years, in nature - less, because they are attacked by other fish. The tail fin resembles a fork, the ventral is similar in appearance to a fan for women. It is curious that young thorns have a richer body color than individuals of old age.

At home, aquarium fish feeds on virtually any food, which is very good for novice aquarists. It can easily be contained in aquarium of different shapes. It is undesirable to let the ternsii into the reservoir, where aquarium fishes with veil fins are already swimming, in order to avoid collisions between individuals. In the photo, the terns swim in the aquarium alone or with fish similar to them.

This fish has several possible color options:

  • Classical. Silver body with two vertical stripes.
  • Veil aquarium fish. This species was first bred in European countries. Not often found on sale. The photo is not much different from the classic terntion, the only thing that is difficult to breed.
  • Albumin ternetia It is extremely rare, different white, transparent color.
  • The most fashionable of this type is termination caramel. It is an artificially bred variety. Why so popular? Thanks to its unusual multicolored artificial color. Difficult to maintain, as derived by chemistry. Mainly imported from Vietnam, where their reproduction is put on stream.

How to maintain and care

Curing can be kept in any tank with water, however, it is desirable to place it in a large volume aquarium. In the photo from the galleries with fish, they are all contained in large water pools. The temperature of the water can be kept around 23 degrees Celsius, and the acidity - 5-7 pH.

Care for aquatic creatures is quite simple. They have a peaceful disposition, neighbors in the aquarium do not affect the ability of this fish to breed. It is not worthwhile to push only very small fish to it, since the terns may grab them by the fins.

You can feed the classic fish food sold in all pet stores. It is inexpensive, enough for a long time. For adults, ternations, besides dry food, can be given live, vegetable and mixed feed. Young individuals - infosoria, and the fry - dry milk, which they willingly eat.

Reproduction of termination

The following conditions must be met at the same time for breeding these inhabitants of aquariums: attaining maturity, which is 8 months old, and a total body length of about 4 cm. Too young or, conversely, too old individuals that are short in size are not suitable for breeding. We describe how the breeding of fish.

  1. An aquarium with low walls is taken, with a volume of about 35 +/- 5 liters. The bottom must be covered with plants. For example, moss, mackerel, nitella or others. Next you need to fill the spawning area with fresh water, and its level should not exceed 7 cm. The temperature should be about 25 degrees Celsius. Lighting is allowed natural.
  2. Wait for about 5 days until the water becomes suitable for planting fish into it.
  3. As a rule, at first individuals will not be ready to breed. Feel hard on them with bloodworms, watch for the feeding of all the larvae. This is done to ensure that ternatsii were ready for reproduction, females recruited eggs, and males - milt.
  4. In the process, the males will follow the females. The eggs roasted over the plant layer will be fertilized. About 40 eggs are swept at a time. Over the entire period of spawning - more than 1000 units.
  5. When spawning is over, the fish must be placed in a free space from the plants. It is necessary to isolate the terntions almost immediately after spawning, since hungry producers can start searching for food by destroying the eggs.
  6. If it is good to feed a couple of heterosexual individuals, then it is capable of reproduction 4-6 times, interrupted for 2 weeks.
  7. The incubation period for spawn roe is up to 24 hours, an average of 19 hours. In order to avoid losses among the hatched individuals, it is necessary to bring the water temperature to 27 degrees, as the fish are thermophilic. Small thorns are small in size, they can be seen when it hangs on the glass of a tank with water and plants.

Due to the simplicity in breeding, peaceful disposition and low cost, terntiony became popular with aquarists. Take a closer look at them, even if you are a newcomer to such a thing. Colored caramel will delight you with its color and decorate your interior.

Aquarium Firefly

Ternesia is a fish from the family of haracins from the South American continent, also known as the black tetra or the mourning tetra. This fish has become popular all over the world due to its subtle beauty and fertility. Compatibility with a large assortment of fish in the aquarium and simple breeding are also the reason for its widespread celebrity.

Scientific experiments conducted on ternenii, served to the removal of genetically modified individuals that can shine under ultraviolet light. Fragments of jellyfish or red coral DNA were inserted into their DNA, as a result of which their color became multi-colored.

These types include termination caramel or multicolor. Coloring injections are given to albino fish forms, giving them bright iridescent shades of gold, pink, green or blue. Multicolor termination is capable of breeding quite healthy offspring, like other transgenic forms of these fish.

Description

Ternesia looks very effective. The body shape is flat and rhomboid, flattened on the sides. On the back there are 2 fins, one of which is fat and does not have hard rays. The anal fin is fork-like, and the ventral stretches to the very tail, resembling a fan or skirt. In size, aquarium fish reaches 4-6 cm.

Looking at this fish, it seems that it is painted with magic silver colors with a greenish shimmer on the back, and 3 transverse stripes are painted against the background of the body. One band crosses the eye, which has a yellow iris, the second is located behind the gill cover, and the third passes from the edge of the dorsal fin to half of the body.

Young individuals are painted more brightly in silver color, and in adults there are clearly pronounced dark stripes. Males are smaller and slimmer than females, the edge of the tail fin is outlined with white edging. Terrestinia can change color when frightened or the deterioration of their conditions of detention. The life of a black tetra is 3-4 years.

Care in the aquarium

Thorns is a peace-loving and schooling fish, unable to bear the loneliness, from which it becomes aggressive. The content of ternation is not particularly difficult. It is recommended to keep fish in a closed aquarium of 30-40 liters for 5-7 termination. For soil suitable river sand, pebbles and fine gravel. The darker the substrate, the brighter the fish will look on its background.

Plants should not block the space, so it is better to choose small-leaved, planting them bushes. A good combination will be with Javanese moss, Echinodorus, hygrophilic, cryptocoryne. Water temperature is 21-24 ° С, hardness is 7-8 °, acidity is 6.5-7, filtration is important. The lighting should be dim, otherwise the black tetra will look pale. The fish is sensitive to lack of oxygen, therefore, artificial aeration and water replacement 1/5 part weekly is necessary.

Because of the special physical structure of the mouth, it is difficult for small fish to take food from the bottom, so a special feeder is installed for them. These fish are unpretentious in food, they feed on any food, vegetable, combined, dry food will be suitable for adult fish. Cyclops, daphnia, rotifers, pipe creeper, small bloodworm, and corret are suitable as live food.

Ternets float on all water levels and are very mobile. In a spacious container it is kept on the territory without thickets, and in a small aquarium it takes shelter in plants. For decoration snags, stones and caves are appropriate.

Breeding

Dilution of terntions at home is not difficult. Black tetras are quite prolific creatures, they have a pair spawning, although pack spawning is often practiced. The reproduction of ternations requires a separate spawning area of ​​30 liters, preferably oblong. The bottom is covered with small-leaved plants and a kapron net to avoid eating the eggs by the parents.

Spawning occurs rapidly, the water parameters change: hardness up to 4 °, temperature 25-26 ° С, acidity 7. A week before spawning, it is recommended that the male and female be kept separate. Spawning occurs as follows: first, the male is planted in the tank, and the female is placed in a few hours later. During this period, you need to feed them with bloodworms.

The spawning itself takes place on days 3-6, when the female will pick up enough eggs, and the male will milk. The male chases the female for 2-3 hours, after which spawning begins. Females lay from 1000 eggs, at the end of the producers it is necessary to plant.

Termination larvae hatch in about a day, and after 3-5 days the fry begin to swim and take food. Infusoria, Nauplii Artemia are well suited. Puberty of terntions occurs by 6-8 months.

Neighborhood in the aquarium

Peaceful behavior black tetra and compatibility with many fish is great for a mixed aquarium. Good compatibility with terns for gourami, swordtails, cardinals, petilias, catfish, discus, scalar.

Unfavorable compatibility with cichlids, barbs and other aggressive species. Smaller species can hurt their voile fins, and the crested itself can bite fish larger than itself.

Diseases

Ternets are quite resistant to diseases, but parasites must be avoided in the aquarium. To maintain hygiene, it is recommended that new fish and plants be quarantined for at least 3 weeks.

A decrease in the acidity of water can lead to acidosis, and an untimely change of water increases the concentration of ammonia, which leads to disease of acetamia.

In any case, it is possible to understand the health of the fish by changing its external signs, for it is necessary to diagnose it accurately. Self-treatment of the disease is carried out by standard means as for other fish: by raising the temperature to 30 ° C and by salt baths.

Common ternetia, and even more voiley, will look presentable in any aquarium and will decorate it with its presence. Even the most beginner aquarists can cope with the content of the black tetra, especially considering its compatibility with many other aquarium inhabitants. Her smooth movements and modest temper, not to mention the attractive prettiness, will deliver a truly aesthetic pleasure to the owner.

Thorns: reproduction

One of the schooling fish that are perfectly accustomed to aquarium glass - ternii. They were first described in 1895 by a Belgian-British zoologist. To see these fish in the wild, you need to go to Brazil or Paraguay. But at home, the fish of this species can contain everyone.

The fish have a rather original body shape, resembling a rhombus. In this case, the body is flattened from the sides, and the tail is very lush and resembles a lady's fan.

While the fish is young, black stripes are barely visible on its silvery body. But when she reaches puberty, the black stripes become perfectly distinguishable. The life span of an animal is three years. In good conditions, the termination can live to four years.

These fish breed by throwing caviar. To carry out the process of fertilization and subsequent reproduction in the home, you need to take a couple of producers. Thorns is a prolific fish.

Males are usually slimmer than females and smaller, they have a brighter body color (especially in the tail zone). However, often the fins of the male have a white rim. A week before the proposed spawning of the male and female, it is better to separate them. A vessel with a volume of thirty liters will be an excellent breeding ground. The bottom should be oblong and covered with plants. Fish ternation: reproduction should occur in water with a temperature of 24-26 degrees. First, the female should be let into the water, and after a couple of hours - the male.

Spawning starts next morning. To speed up the process, you can put the vessel under artificial lighting. Ternation female will lay off about 600-1000 eggs. When the caviar throwing is over, the producers need to immediately set down. After a day, the first fry will appear, in five days they will swim and begin to eat food. New individuals reached sexual maturity in six months. But two years later, reproduction will already be difficult.

Reproduction of this type of aquarium fish is not at all a complicated matter. The main thing is to know the basic laws of nature and create the most favorable conditions for producers.
