For reproduction, a spawning ground with a volume of 46-50 liters is required. Before spawning, producers must often and abundantly feed all types of live food. The impetus for spawning is a partial water change with a simultaneous increase in temperature to 27-28 ° C. A few pots for the female's hideout and several large, flat stones should be placed in the spawning area. The female can spawn up to 1500 eggs. The male should be planted after spawning.
