Habitat and Ecology [top]

Habitat and Ecology:Clarias theodorae is a demersal species that lives in vegetated areas in small swamps and streams. It also occurs in delta areas and lagoons of rivers. Occasionally it is found in cataracts, hiding under rocks (Teugels 1986). It is one of the species that is associated with floating islands that break adrift from peripheral marshes. Such floating islands may assist in the dispersal of this species in Lake Malawi. It feeds mostly on insects (Coleoptera, ants, Chironomid larvae) (Teugels 1986, Konings 1990) and occasionally small fish.
