| Remarks |
Inhabits rivers and lake fringes, swamps and floodplains (Ref. 28714). Adults and sub-adults occur in open water but they prefer shallow inshore regions, especially the vicinity of swamps (Ref. 34291). Generally becomes more active during the last hours of the day, its activity increases at dusk and probably continues during the night. During the day, this fish regularly leaves its site to approach the surface in order to breathe. It breaks the surface with its large mouth, filling its lungs with air, then allows itself to sink down. Food search involves mud-digging on open bottoms and taking up mouthfuls of dirt and algae which are then spat out (Ref. 42701). |
