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.
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.
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.
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.
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.

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.
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.
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 cannot breed.
We describe how the breeding of fish.
- 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.
- Wait for about 5 days until the water becomes suitable for planting fish into it.
- 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.
- 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.
- 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.
- If it is good to feed a couple of heterosexual individuals, then it is capable of reproduction 4-6 times, interrupted for 2 weeks.
- 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.
Ternesia is a fish from the family of haracins from the South American continent, also known as “black tetra” or “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 wide 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.
