Ternesia: content, compatibility, breeding, photo-video review

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.

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.

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 calmer 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. 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.

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.

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.

Ternetia has a rather original diamond shape. The features of these fish also include the presence of two fins on the back. One fin, which is closer to the tail, is adipose, as it does not have hard rays.

The tail fin of the fork-like tetra.

The most unusual is the ventral fin, which stretches to the base of the tail. On the outside, a black tetra can reach a body length of up to six centimeters. In captivity, thorns very rarely grow to five centimeters.

There are several breeding forms in the world that have elongated voile fins. There are also color variations, but there is an opinion that it was not without special gene modifiers.

Ternation usually lives up to 4 years. The black tetra is a fish that prefers to live in packs.

For ten individuals need an aquarium, the volume of which must be at least 50 liters. Ternesia does not tolerate loneliness. If she is left alone, she becomes overly aggressive.

A flock of these beautiful creatures can be kept with other species that are also peaceful.

Black tetras fight only between individuals of their own species, they are usually harmless, but sometimes it happens that they damage each other’s fins. Also experienced aquarists do not recommend containing terntions along with some slow-moving fish, because when feeding fast tetras will not allow them to eat, slow-moving fish will simply starve.

If the conditions of detention have worsened, the terntions will begin to change color and become completely pale.

For a mixed aquarium, ternets are ideal. They have poor compatibility with fish living with them in the same aquarium, which have a small size or large fins compared to the tetra, as it will constantly bite them.

Therefore, perfectly suited for the joint content of guppies, swordtails, petilia.

For peaceful coexistence, it is also necessary to acquire a large aquarium so that the terntions can retire, hiding in the vegetation. If you be attentive and keep black tetras in comfortable conditions, she will live peacefully and please the eye for a long time.

Danio pink: content, compatibility, breeding, photo-video review

This article depicts and describes the pink, artificial breed danio rerio! True danios pink looks like this:

Order, family: Carp.

Comfortable water temperature: 21-25 ° C

Ph: ph 6.5–7.5, water hardness: 5-15 °.

Aggressiveness: not aggressive.

Compatibility Danio Pink: compatible with all “peaceful fish”: danios, terence, minor, tetra, scalar, soma, etc.

Useful tips: In my opinion the most beautiful fish of the kind “danok.” Look great flock, on a dark (blue) background of the aquarium film.

Fishes quick and gregarious. They can coexist with many species of fish, even with fish of medium and increased aggression: scalar, goura and even with small cichlids.

In order that the pink color of the fish was juicy, I recommend to buy specialized food (for example, Tetra-color).


Danio pink lives in the slowly flowing waters of Southeast Asia.

A small fish with a body length of up to 4.5 cm. The body is elongated, flattened laterally. Body of fish beautiful pink, along which alternate white stripes pass.

Fins transparent, colorless.

Fish are kept in the aquarium flock (from 6 copies). Danio pink contain in general aquarium with a length of 60 cm and a volume of 20 liters. The decorations of the aquarium can act – thickets and floating plants, stones, snags.

Fishes also need free space for swimming.

Comfortable water parameters: temperature 21-25 ° С, dh 5-15 °, ph 6.5–7.5, regular weekly water changes (1/5) will have a positive effect on the health of the fish. Need filtering and aeration.

Feeding Danio Aquarium Fish must be correct: balanced, diverse. 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.
