Africa: Kasai drainage including the Lulua and Kwango (middle Congo River basin), upper Congo River basin including the upper Lualaba, Luvua, Lake Mweru, Luapula, Lufira and Upemba region (Ref. 55074), upper Cuanza, Cunene, Okavango, Lake Ngami, Zambezi, Limpopo, Sabi, Lundi, northern tributaries of the Orange River, Lake Malawi and Bangweulu (Ref. 5163).
Occurs in widely diverse habitat. Favors areas where plant cover exists along the edges of rivers, lakes or swamps. Prefers shallow sheltered waters and does not colonize the open water of large lakes. Adults feed preferentially on filamentous algae, aquatic macrophytes and vegetable matter of terrestrial origin (leaves, plants, etc.) (Ref. 3). Juveniles feed small crustaceans and midge larvae (Ref. 6465). Forage fish for bass (Ref. 7248). Undertake seasonal upstream migration and breeds before and during these migrations (Ref. 13337).
