Biologie     Glossaire (ex. epibenthic)

Lives in well-vegetated quiet waters or near submerged trees or rocks in the lee of the river’s main current, lunging out to capture prey (Ref. 5614). Juveniles occur mainly in lagoons and secondary channels (Ref. 7248, 94654), while adults prefer deep main channels and permanent lagoons (Ref. 7248). Large specimens patrol open water of rivers and lakes, never very far from shore (Ref. 246). Predator on fish but also feeds on aquatic and terrestrial insects, shrimps and small crabs (Ref. 13337). Adults often feed on squeakers (Ref. 7248, 13337, 94654). Mouthbrooder (Ref. 246, 13337, 13721) and multiple spawner (Ref. 13337). Constructs shallow nest on sandy or muddy substrate in shallow water (Ref. 13337). Reported to have adverse impact on native fish species in Zimbabwe (Ref. 94654).
