Развядзенне / развядзенне

In its natural habitat, spawning occurs from September to December with the arrival of summer rains (in the Southern Hemisphere these are warm months). In the home aquarium, seasonality is not expressed. They spawn in the twilight among plants, attaching eggs to the surface of the leaves. Females lay only a few eggs a day, so the whole process stretches for several weeks. The incubation period lasts 5–9 days at a water temperature of 24 to 29°C. The emerging fry gather in a group and are near the surface. After 12 hours, they begin to eat. In the early days, they are only able to take microfeeds, such as ciliates. As they grow, they will begin to take larger meals. Juveniles of different ages can create feeding problems.

Although adult fish do not show predatory tendencies towards their offspring, it is still advisable to transfer the fry to a separate tank for ease of maintenance.
