For spawning, the fullest female and 2-3 active males are selected, which are seated in separate tanks for a week. The day before spawning, the producers do not feed.

Spawning starts at 1-3 days at dawn.

Female productivity – 100-200 small transparent eggs. Mature fish after spawning are deposited, and the aquarium is completely obscured.

The incubation period is 24-48 hours. On the 4-5th day, the larvae swim and can feed on rotifers, nauplii of crustaceans and ciliates, then vegetable food is added.

In small quantities, the feed should be present in the spawn with the fry constantly. Water changes are carried out more often than in adult fish.
