Barbus mutant or moss barbus has a distinctive feature – a fluorescent body that shimmers and creates a glowing effect. Individuals are mobile, playful and endowed with a peculiar character.
The moss barbus appeared from the mutagenesis of a Sumatran barbus. This subtype and eggs were irradiated, which led to a mutation of the species.
Changes in the species occur even because of the influence on the eggs of nitrogen or oxygen, but such changes occur extremely rarely. Lives miracle fish in Thailand, Colombia and Sumatra.
In 1977 it was brought to the USSR from Czechoslovakia.
The body of a mutant fish is rounded with a high back, pointed muzzle and small fins. It grows up to 5-7 cm.
Mossy barbs differ from Sumatran body color from dark blue to rich green. The fins are painted black with a red-orange edging. Head usually red shades.
With age, the color of scales fades, but does not lose its reflection.
Barbusses are gregarious, peaceful and calm fish. Alone can show aggression and hooliganism, so in the aquarium fish should be at least 7 pieces.
The life span of a mossy barb is from 4 to 5 years, sometimes up to 7.
Barbus green not picky and easily tolerates a change of scenery. The main task of the owner is to ensure the cleanliness of the aquarium, periodically update the water and feed it on time.
Green barb brought artificially. But this does not prevent him from being hardy and not getting sick. Fish are resistant to stress and easily tolerate a change of environment.
In the aquarium bought only high-quality filter for water purification. Aeration system saturates water with oxygen.

The Sumatran mutant is a mobile and energetic fish that loves a large space, so it needs a large and long aquarium. Barbus contain with his relatives and the aquarium should be at least 50 – 70 liters with a lid. Each week it is necessary to update the water at 25% of the total volume and carry out a siphon bottom cleaning.
If the aquarium is small and there are a lot of inhabitants, then it is better to replace the water in full to avoid pets intoxication.
- water should be well saturated with oxygen;
- temperature range 21–25 degrees;
- acidity in the range of pH 6.5 – 7.5;
- rigidity from 2 to 30 degrees.
Place bulk plants on the back wall and sides of the aquarium. They create blackouts in which barbs are hidden and retreated. Preferred algae with large and wide leaves.
The front wall cannot be blocked up so that the fish can move freely.
The bottom of the aquarium is filled with 4-5 cm of sand with a gravel content of the middle fraction. Snags or stones with holes are put on the dressing so that pets can hide and play.
The light in the aquarium should be diffused, because the fish do not perceive too bright lighting. Their habitat should be lit at least 16 hours a day.
Mossy mutants are snooty, mobile, constantly swimming one after another. They are kept in packs and, when choosing their neighbors, take into account the characteristics of the fish.
- marble gourami.
Do not purchase small, sedentary, as well as fish with long tails and fins. Mutants of such neighbors chase, bite and pluck.
If you put large fish in the aquarium, they will not give rest to mossy mutants.
The green barbus does not get along with liliusi, cockerels, guppies, telescopes.
In 3-4 months, with a body length of 3 cm, they become sexually mature. For breeding offspring, choose the most active and fast pair.
Unlike the male, the females are larger and have a rounded belly. Males are smaller and have a saturated color.
Their face is of a pronounced red color. There should be no deviations in appearance.
At the time of purchase it is impossible to determine the sex of the barb, an exception if already mature individuals are sold in a pet shop.
Good quality of seminal fluid and activity of the male gives more than 50% of viable larvae.
To get 75% of barbs – mutants, it is better to reduce the individuals pure color, with no impurities. To achieve a high survival rate, mutagen barbs are crossed with Sumatran.
At the end of the spawning of mossy mutants, 25% come out, light-colored – 40% and Sumatran – 30%.
In preparation for spawning, the fish are densely fed with high-quality live food or dry with fat-soluble vitamins (A, D, E). Prior to spawning, females and males are divided into 10–14 days.
It is necessary for ripening caviar.
If the female is over-exposed, then a cyst is formed. Then the scales of the fish bristle up, the individual floats to the surface, turning onto its back and then dies.
For breeding choose a low capacity up to 30 cm with an area of 400 cm. Square.
At the bottom of the spawning rack stack dense mesh with holes of 3 mm. This helps prevent eating eggs.
Moss and nylon sponge in the form of a ball are put on the net.
On the first day, the vapors are deposited in another aquarium with a water temperature of 25 degrees and with sufficient aeration. Better to do it in the evening.
Transfer the manufacturers in a separate container, half filled with water from the general aquarium and half prepared for spawning. A couple is kept in a bailout for 20–30 minutes, then released into the spawn.
On the second day, an extra lamp is placed up to 40 W and left for 1 day.
Fertilization in mutants occurs in the morning. If the fish do not want to spawn, then I increase the water temperature by a couple of degrees.
If after this there was no spawning, the male is replaced by another.
After fertilization, the female begins to spawn at an interval of 30 minutes and lasts about 8 hours. During spawning, the female produces 200 – 300 eggs.
The remaining eggs in the abdomen are removed by fingers with the help of stroking the tum.
For the next 24 hours, the spawning wheel is darkened and the amount of water is reduced by 9 cm, and after 14 hours, the grid removed from the caviar is removed. After 12 hours, add one-third of boiled water and increase aeration.
A day after laying, the larvae are born, which will be able to swim on their own within three days and eat on the sixth day. Lure start with light food: egg yolk, ciliates, Artemia or feed for fry. The first three days they feed the babies on the barbs 4–5, taking into account the night time. The next three days the young are transferred to a capacity of at least 50 liters with an area of 500 * 500 mm.
After two or three weeks, the fish are moved back into the large aquarium with 10 fry per one liter of water. For future manufacturers’ health, they make quenching by lowering the water temperature by a couple of degrees during the day.
This procedure is repeated 1–2 times in 7 days.
When the mutant mutants grow up they can be given pipe makers, moths, green brain peas and porridge.
Newborn fry mutants are kept in small aquariums with a water temperature of 26–28 degrees. After a few months, the temperature is lowered to 24-25.
If you do not follow the rules, babies can grow with the deformation of the body, deformity and various deviations.
- Due to lack of oxygen it is possible to change the structure of the fins.
- Changes in water temperature affect the respiratory system.
- External damage violates the structure of the spine.
Kids barbs grow very quickly, so you need to monitor their growth and deposit them in a larger capacity.

- The mossy mutants have a Weberian apparatus, thanks to which they have a sharp ear.
- It is better to buy an oblong aquarium.
- Barbus often hang head down.
If the fish take this position and work more frequently with the gills, the mutants lack oxygen. Look at the temperature of the water and, if possible, lower it, or increase the aeration.
To ensure a full and healthy life, moss mutants need:
- contain in large aquariums over 50l and flocks;
- be sure to maintain the necessary water parameters;
- create comfortable conditions in the aquarium and sufficient aeration of water;
- follow the lighting;
- observe the neighborhood and breeding rules.
