Aquarium fish ternation


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.

Detachment, 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 tank 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.

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 usually treated with a temperature increase of up to 30 degrees, methylene blue, tripaflavin, salt baths, 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.

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.


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.


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.


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.


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 ternsyne get along 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.


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.

Black and White Terns - Content Rules

Black tetra, thorny (lat. Gymnocorymbus ternetzi) is also known as "black widow tetra" - it is a small freshwater fish of the Haracine family. Confusion often occurs because it is not the only fish known as "tertion". She has a "cousin" brother, Gymnocorymbus thayeri, who is also called "tertion".

Gymnocorymbus thayeri is a shy fish and not as hardy as a "black widow." In addition, there are other color forms with a beautiful appearance. These include white terns and colored tetra (caramel). The black tetra Gymnocorymbus ternetzi was described by Bulenger at the end of the 19th century. This fish is found in South America: in the rivers of Paraguay, where it lives in the upper layers of water.

Description. Content policy

Ternesia has a deep rich color and a compressed body. This fish reaches the size of 5.5 cm in the home aquarium. Life expectancy from 6 to 7 years. It is distinguished by two vertical stripes, and well-developed dorsal and anal fins. During puberty, the saturated black lines on the body fade. The body is diamond-shaped, with a silvery sheen.

Black ternation is easy to maintain, perfectly adapts to changes in water parameters, and is an excellent decoration of the general aquarium. This aquarium fish is omnivorous. In the wild, black tetras feed on worms, small crustaceans and insects, but in captivity they usually eat varieties of live, fresh, and branded products. Crank, Artemia, Cyclops they also love.

See how to keep black thorny in your home aquarium.

Since they are active swimmers, the ternation must inhabit a reservoir of 50 liters per individual. They love soft, peat-filtered water. Fish prefers vegetation cover and dark gravel as a substrate.As plants, you can choose Javanese moss, cryptocoryne, echinodorus. She also needs an open area to swim freely. Aquarium should be closed with a lid, because this fish jumps well.

The content of the black tetra is possible only in pure water. An aquarium is a closed system that requires meticulous care. Over time, organic substances decompose, nitrates and phosphates accumulate, increasing the water hardness. Therefore, water should be replaced regularly (25% of the total) once a week. Aeration and filtration are required.

Aquarium Lighting: Moderate

Temperature: 21 to 26 ° C

Dilution temperature: 27 to 29 ° C

PH range: 6.0-8.0

Stiffness range: 3-30 dgH

Salinity: does not like salted water

Water flow: moderate

Swimming area: this fish will swim in all layers of water.

Ternesia is an active fish, and can be aggressive to the tail and small fish. Not recommended content alone. In large groups, optimal compatibility. Each fish will focus on each other, and not on smaller fish. Compatibility in the general aquarium is possible with fish of similar sizes. With age they become calmer. Ternetia gets along well with the majority of viviparous, danios, rassori, other tetras, the peaceful inhabitants of water bodies, as well as some dwarf cichlids.

Like most aquarium fish, tetra is prone to scale diseases, parasitic invasions (protozoa, worms, etc.), ichthyoftorosis, and bacterial infections (common). The black tetra is extremely hardy, and the disease does not appear if you provide quality aquarium maintenance and care. Remember that raw soil and scenery, new fish can be a source of disease. Make sure that all new fish have passed quarantine, and that the water balance in the aquarium is not disturbed.

Sex differences. Breeding

The male's dorsal fin is more narrowed and longer than that of the female. Mature female is more rounded than male. The aquarium ternetia was bred in captivity, various color forms appeared later, and they have lush fins. Perfect for beginners aquarists who decided to breed fish.

Look at the spawn spawn.

For breeding to be successful, females must dwell separately from males for 7 to 10 days before spawning. You need to feed them with live foods frozen. Then they can be run into a 40-liter tank, where a sponge filter and aeration compressor should be installed. Water temperature in spawning, stimulating reproduction: from 27 to 30 degrees Celsius. Neutral acidity, water hardness below 15 dH. In the tank you can put Javanese moss, which will serve as a substrate for caviar. The separator net is also suitable, but the caviar must pass through without any damage.

Breeding will begin when the males start chasing. The female will set aside from 500 eggs for 2-3 hours. After successful laying, manufacturers must be removed so that they do not eat caviar. All unfertilized eggs should be promptly removed so that they do not become covered with fungus. The larvae will hatch in 18-36 hours, and the fry will swim in a few more days.

Maintenance and care of the fry: to feed with infusoria during the first days of life. Later, you can give a micro-worm and nauplii Artemia. The biggest problem is that the fry are prone to starvation if they cannot find a source of food in a dark reservoir in a timely manner. Give the fry a lot of light, day and night, until they are big enough. Then they will be able to eat the newly hatched Artemia.

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.


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 ternations 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.


Dilution of ternations 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.


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, to accurately determine the disease it is necessary to diagnose it. 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.

Aquarium fish - ternitse

Ternesia has several names, in particular, mourning or black tetra.

The homeland of this fish is South America, and more specifically, the flowing and slowly flowing rivers of Bolivia, Paraguay, Brazil. In natural conditions, this fish reaches 6 cm, but in aquarium breeding conditions it usually grows to 4-5 cm. The main color of tetras is silver with transition to dark gray, almost black.

The back is yellowish-olive. Juveniles are darker than adults. It has three distinct black vertical stripes: the first passes directly through the eye, the second frames the gill covers, the third at the base of the pectoral fin.

Mature ternation has a graceful body shape, rather high, laterally compressed, not too long, diamond-shaped. Clearly marked full sideline. The eyes are large, with a yellowish-brown shell, in the abdominal part of the body there is a mouth. The fins of this fish deserve special attention.

There are two dorsal fins in the terniatia: one is membrane, high and short, the second is fatty, small, without axial rays. The presence of a second dorsal fin attached at the base of the tail is one of the characteristic features of this fish. The pectoral fin is two; the anal fin begins in the middle of the abdomen and ends at the base of the tail. The pectoral fins and tail are transparent to white, while the dorsal and anal fin are dark, almost black.

The second and main feature for the fish of ternia is the anal fin, which looks like a black open mourning fan, for which it was called the mourning tetra.

In the food, this fish is absolutely unpretentious, almost any kind of food will do: dry, vegetable, combined, live. Restrictions exist only for feeding fry.

The fish is very peace-loving, belongs to the category of schooling, the content of 6-8 or more individuals is recommended, remaining alone, can become aggressive. Mourning tetra does not require for its content very large aquariums, but preferably not less than 20 liters with a temperature of 20-26 ° C and a pH of 6.0 - 7.5 with a large number of water thickets.
