Facultative air-breathing (Ref. 126274); This carnivorous fish lives in streams, lakes and zones of flood (Ref. 4910, Ref. 41580). In Lake Tanganyika it is mostly found at the mouth or delta of rivers and lagoons (Ref. 36901). Not commercially important (Ref. 4967).

這個肉食性的魚生活在溪流,湖與洪泛區中。 (參考文獻 4910, 參考文獻 41580) 它是發現於大部份的嘴巴或河川與潟湖的三角州的在坦噶尼喀湖.(參考文獻 36901) 不是商業重要.(參考文獻 4967)
