The bruise is characterized by an unusual spawning process. The peculiarity lies in the fact that the fish uses a “natural incubator” – a living mollusk, which belongs to the family of unionions. Spawning occurs in several stages, which last from May to August.

During the mating season, males acquire a purple-red color. and start fighting among themselves for the attention of the females. At the same time, they “pick up” bivalve mollusks in which the larva will develop.

To postpone spawn bruises, use live mollusk

In females, there is a transparent organ in the form of an oviduct tube. It can reach from 4 to 5 cm in length.

This oviduct is densely filled with yellow eggs. There are about 200-250 pieces.

During spawning by a tubular organ, eggs are laid in shells. One can fit from 5 to 30 pcs.

In the same shell, the male puts the milk. Sometimes it happens that in one shell can be from 10 to 15 clutches.

Larvae begin to appear after 3-4 days. The basis of the diet of fry – plankton, and after 17−20 days in the diet already includes plant food.

The best way to catch a bitch is to use the smallest hook.

  • a float with a small carrying capacity, by which you can notice even a slight touch of the bait;
  • monofilament line, which makes the tooling invisible;
  • the smallest hook.

Rod must have a minimum weight. The optimal size is 3.5–5 m. Dough, steamed wheat or black bread crumb are used as a nozzle. For bait fit a piece of worm, bloodworm and moldy worm.

Cool brisk but unsure.

The optimum water temperature is 18−22 ° C. It is important that the aquarium is constantly filtered and aerated water. It is recommended to add clean water once a week.
