Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Occurs in well-vegetated swamps and along the edges of rivers (Ref. 6465). Also occurs in fast-flowing reaches over sand and rocks (Ref. 6465, 52307). Feeds primarily on small fish (Ref. 6465, 52307), also on shrimps and insects (Ref. 6465). A female (Ref. 52307) mouthbrooder which breeds in spring (Ref. 6465). Aalso caught with drawnets (Ref. 6465).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Female incubates eggs in her mouth. Parental care is exercised for a short while after hatching when the juveniles move off to shallow grassy areas and there they remain, in the Upper Zambezi, until floodwaters recede and force them back to the main river. They seek refuge in lagoons and backwaters until reaching a size large enough to avoid predation by tigerfish in the open waters of the river.
