Aquarium fish ternation

maintenance, care, compatibility

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.

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.

Ternesia content dilution compatibility description feeding.

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.

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


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.


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.

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.


Often, people who buy an aquarium, do not know who to make a new home. When acquiring a fish for the first time, I want it to live happily ever after, and the owner’s little experience doesn’t hurt her at all.

Among the waterfowl, which are ideal for beginners, the place of honor is ternation.

South American women rarely get sick, and they are traditionally treated with fever up to 30 degrees, methylene blue and baths with salt. If necessary, contact the experts.

On average, this species of fish lives for 3-4 years, and under good conditions, up to 5-6 years.

To be proud of your aquarium, it is not necessary to live there fashionable or large inhabitants. The little terns will be one of his best jewels.

Despite its mourning stripes, it is a very cheerful, cheerful and bright fish. It is quite inexpensive – 60 rubles.

Video: how to contain fish terniyu:

The aquarium fish, terne caramel, came to us from the rivers of Paraguay and Argentina just recently in 1993. She got acclimatized in the new environment, reproduces well, and it is not difficult to care for her.

A small guest from the Western Hemisphere, the owner of a small – from four to five centimeters – egg-shaped body, compressed laterally, her eyes are yellow. On the back there is a high short membrane fin, and at the tail – fat and small.

From the middle of the belly of the caramel goes anal fin.

The nature has dressed caramel thorn in olive-green outfit. Black stripes with wide corners picked up the main coloring. One dark band goes through the eyes, the other through the gills, and the third rises to the dorsal fin.

The pectoral fins of a foreign fish, as well as its tail, are transparent white. The anal and spinal are quite dark.

It should be noted, breeders have tried: today, red and veil varieties of caramels have been bred.

To distinguish between “boys” and “girls”, you need to look at the tail – in the males it is white at the end. In addition, female caramel fish are larger than males and slightly lighter.

The young aquarium fish, ternetium caramel, is distinguished by a brighter color contrast, and black stripes are clearer. With age, the color fades, but during the breeding season caramel thistle blooms again.

Why is the second name stuck to the Latin American caramel? Ternetia caramel – an albino colored aquarium fish, which is injected with a solution of water with fluorescent dyes.

The solution enters the bloodstream, which spreads the paint to the muscles and completely changes their color. Sometimes even fins get a shade.

Then the newly-made caramel is released into clean water, where she begins to get used to life in a new outfit.

Unfortunately, these painted water creatures do not last long. Yes, and with the reproduction of colorful fry does not work.

If the water house of your favorite caramel lush vegetation and good aeration, it multiplies easily. Also, for more active breeding, the male and the female of ternation are fed with bloodworms, and the rest of the food must be removed from the water. After spawning, adult individuals are better off to seed, so that the eggs are not eaten.

Fry appear after three days. To feed them you need a special small food.

The children of the peace-loving aquarium fish are divided in size and seated so that they do not start to feast on each other.

Fish aquarium ternatsiya: princess of the underwater kingdom

The aquarium fish, ternetia, is from the family of haracin. Its habitat in the wild – South America, more precisely, the rivers Rio Negru and Paraguay. In their homeland fish belong to the category of predators.

They were brought to Europe a relatively long time ago – in 1933. A very unpretentious habitat and, unlike its wild relatives, a peace-loving, aquarium fish, the terniya enjoys well-deserved love among admirers of the inhabitants of the underwater kingdom.

Because of its undemanding nature, it is ideal for novice aquarists for breeding.

Ternations grow up to five centimeters in length. They have a high body, as if crushed from the sides, the shape of which somewhat resembles a rhombus. The back of the fish has a green-olive color.

On the brilliant silver scales of the body there are three vertical stripes of black color, and the first of them cuts the fish eye in half, as it were. The aquarium fish also has a “special sign”.

Her anal fin has the shape of a skirt. For this, razvodchiki often called terniyu fashionistas.

Recently, a peculiar tendency has appeared – to carry out artificial coloring of albino fish. With the help of various dyes, they are given bright shades, as a result of which a new species has appeared – the aquarium fish, the caramel termination.

True, this feature is not inherited, moreover, almost 90% of the colored individuals acquire their natural color after time.

What conditions are really considered optimal for the content of ternsii? Since this fish is a schooling fish, then for 8-10 individuals a reservoir of at least 80 liters is required.

Terence likes warm water, so the temperature must be constantly maintained at +26 degrees. If we talk about the level of rigidity, then the optimal indicator is 18 units.

Acidity is necessary to maintain in the range of 6-7 pH. Demanding termination and oxygen, and therefore the tank must be equipped with devices for artificial aeration of water. The bottom in the aquarium should be sandy, and the plants and decorations should be seated and arranged so that the fish have free space for swimming.

The best neighbors of thorns are considered catfish, guppies, gourami, petilles and scalar.

As for feeding the fish, then the owner of the aquarium will have no problems with this. Despite its predatory nature, ternation can well do with dry and high-quality artificial food.

True, this fish will not refuse from the bloodworm, the pipe worker, the Cyclops, and both in live and frozen form.

Reproduction of the offspring of termination is ready from eight months, but the average lifespan (under appropriate conditions) is about four years.

Still, the aquarium fish is amazingly beautiful. The photos given in the article clearly demonstrate their extraordinary appeal.

And unpretentiousness and friendly disposition make these fish the desirable inhabitants of any aquarium.
