Africa: Lake Tanganyika and the Lukuga River (upper Congo River basin) (Ref. 5714, 52346).

Biology     Glossary (e.g. epibenthic)

Swamp-dweller (Ref. 6770). Juveniles are coastal and gregarious while adults wander over the sandy bottoms by themselves (Ref. 6770), in shallow inshore areas of the lake, in lagoons and river mouths (Ref. 4967). Feeds mainly on crustaceans and insects, along with some plants (Ref. 52307), but also a mollusc eater (Ref. 10616, Ref. 6316). Female carries the eggs (Ref. 1872).
