🥚 Reproduction

Nests are made on sandy or loamy bottoms in water 40-80 cm deep, or more sparsely in depths of a meter or more; they are circular basins with a diameter of 115-185 cm, about 20 cm deep in the middle with a rim raised 7-8 cm above the surrounding level; spawning occurs at night, the fishes seeking deeper waters during the day to avoid high temperatures and intense illumination . Reproduction is seasonal, usually taking place during the dry seasons from June to September and in February; can reach maturity at a size of 15 cm; breeding behavior is similar to that of its congeners (e.g. O. niloticus) .
