Habitat and Ecology [top]

Habitat and Ecology:	Little is known about this species ecology. In the Lake Rukwa drainage it prefers the lake to rivers where it is very numerous (Seegers 1996). It lives in shallow waters in the marginal vegetation feeding on a wide range of food items including plant matter, odonata larvae, chironomid larvae, terrestrial insects, gastropod molluscs, fish scales, zooplankton, and phytoplankton (Seegers 1996). In the Ruvu River the species seems to spawn in the rainy season when they migrate into smaller steams (Seegers 1996).
Systems:	Freshwater
