Description, reproduction, conditions of keeping erythrozonus fish

For beginners, aquarists are recommended to choose the most unpretentious species for the experience of breeding and keeping fish. These include and erythrosonus – a beautiful unpretentious fish with a peaceful nature.

Another argument in favor of choosing this particular fish is that it feels good in aquariums of small volume.

Erythrosonus has a peace-loving character and adapts well to small aquariums.

Under natural conditions, the fish erythrosonus lives in the northeast of South America in the waters of the state of Gayana. Her favorite places are the shallow-water creeks of the tributaries of the Essequibo River, hidden by thickets of jungles hanging above the water.

Now on the market there are fish of artificial origin, it is impossible to find those caught in natural conditions.

Fish length up to 4 cm, translucent body with a bright and clearly visible red-coral stripe running from head to tail. Erythrositis, like all tetras, has a slender, almost flat body, its weight does not exceed 1 gram.

Another distinctive feature of erythrosonus is a red outline above the eye and a flickering spot below it in blue.

In females that are noticeably larger in size than males, the belly is rounded and the back is much wider. Males have a slender body.

Their coloring is noticeably brighter, on the fins white spots stand out strongly.

By behavior, both females and males do not differ. Only during the breeding season, female individuals become more sluggish in their movements, and the males, on the contrary, move more actively throughout the aquarium.

There are no special conditions for keeping a firefly’s tetra (such a common Russian name for erythrosonus). Even a beginner amateur aquarist may well create the right conditions.

The aquarium is better to choose at least 60 liters, as these fish are gregarious and feel better in the company of 6-7 individuals. The parameters for water are as follows:

  • temperature in the range of 23−28 degrees Celsius;
  • acidity in the range of 5.8–7.5 pH;
  • periodic change of water.

It is quite simple to decorate an aquarium: a few snags or small figures at the bottom, the very bottom is covered with dark river sand, floating plants are desirable for dispersing direct sunlight. At the bottom put several washed brown leaves of medium size, which mimic the living conditions of fish in natural conditions.

Tetra firefly is not gluttonous and whimsical in the choice of feed. With pleasure absorbs both live and frozen feed.

It is advisable to alternate animal feed with dry or canned. With long-term feeding with monotonous food, the tetra becomes faded and slows down its growth.

The frequency of feeding – two or three times a day in small portions. The fish feeds from the surface of the water or in its thickness.

Excessive food that has fallen to the bottom of the aquarium is seldom absorbed by it.

Before spawning a separate aquarium is prepared. The recommendations are as follows:

  • pour the prepared water to a level of about 15-20 cm;
  • plant several plants with small leaves (suitable and affordable Javanese moss will suit);
  • to provide blackout, the minimum amount of sunlight should fall, as the eggs are very sensitive to light.

Erythrosis eggs are sensitive to light.

Water in spawning should be soft with a pH level of 5.5 – 7.0 and a temperature in the range of 25 – 28 degrees Celsius. Before spawning, fish are fed with animal feed 2 times more often – up to five times a day.

The fish are ready to breed when the male begins to stalk the female and tremble gracefully in front of her with his whole body. Then the fish are caught (preferably in the evening) and in the morning of the next day they are ready to spawn.
