Habitat and Ecology

This is a demersal species, which inhabits dense vegetation along margins of rivers and floodplain lagoons (Skelton 1993). Often found in lagoons and backwaters in shallow water just underneath the surface vegetation (Bell-Cross and Minshull 1988). It feeds on aquatic insect larvae including a large component of Chironomidae (Bell-Cross and Minshull 1988). This is the smallest mormyrid known from Lake Malawi, not exceeding 10 cm in length. Reported to occur in northern areas of Lake Malawi where it is common in streams and swamps.
