Aquarium fish Varna: photo, keeping and feeding, breeding and breeding

Size up to 30 cm. It inhabits the Uara in the Amazon River basin and in the fresh waters of Guiana.

Sex differences are weak. Males are usually larger than females. It is necessary to keep the uaru in a spacious aquarium with shaded areas, with large, but not aggressive species of fish.

Water for GH content up to 15 °; pH 6.0-7.5; t 25-30 ° C. When the water temperature drops below 22 ° C, fish are prone to colds.

In the aquarium contain a group of fish, since the pairs are determined independently. Breeding water: GH up to 8.0 °; pH 6.5-7.0; t 28-30 ° C. Breeding conditions are common to all cichlids and mainly depend on the successful selection of a pair.

Fry, like Discus fry, are fed by the secreted epithelial secretion of the skin. Starter feed – artemia.

From two weeks of age it is necessary to introduce plant foods (lettuce and dandelion leaves) into their diet. Vara reaches sexual maturity by the year. Uara female throws up to 500 eggs.

The main difficulty in breeding large cichlids is the selection of a pair of producers. The only way to guarantee success is to grow fry growers. 8-10 medium sized fry should be selected and grown in a spacious aquarium with a balanced full feeding, good filtration and regular water changes.

From the grown fry, a pair is taken that shows mutual interest. Usually the Uara male in the formed pair flirts with the female and drives away other fish from her. A couple is deposited in spawning and, by raising and then lowering the temperature and reducing or increasing the hardness of the water, stimulate the fish to spawn.

The correctness of the selection can be controlled only by the shape of the anal tubercles in the spawning process, since two females in cichlids can imitate spawning. In this case, one female spawns and the other plays the role of a male.

Naturally, all the caviar at the same time is unfertilized. With a good choice of a pair of breeding difficulties does not arise.

Buy uar you can in a specialized nursery. You can find out the price of your fry on the bulletin board.

Pictures and photos of the Uary can be found in the species and breeds section.
