The breeding process is quite simple, but the behavior of males during spawning can be unpredictable. When building the nest, the male drives everyone away from it, including females, so the presence of plants for retreat and cover becomes important. The stimulus for spawning is the inclusion of meat products in the daily diet. At a certain point, the male begins to form a bubble nest on the water surface, and the female gradually fills with eggs, which noticeably increases her size. Upon completion of construction, the courtship period begins; the male forms a pair with one female, and he will chase other females in the aquarium. The female releases eggs into the water, where the male fertilizes them, then collects them with his mouth and transfers them to the nest. After spawning, the female leaves her partner, and the male remains to guard the offspring. Fry appear approximately 12–36 hours later and begin to swim freely around the aquarium on the third day. It is important to isolate the fry from the parents, as they may eat them. If spawning occurred in a community tank, the fry should be caught and transferred to a separate tank with similar keeping conditions.
