Description

The longfin sandsifter is a cichlid endemic to Lake Malawi in East Africa. The species grows to about 16 cm and inhabits open sandy areas at greater depth. With a downward-protrusible mouth it digs and sifts sand to extract insect larvae and other soft invertebrates, a specialised feeding mode of the genus Lethrinops. The body is silvery; males develop elongated fins in the breeding season, to which the name refers. As a maternal mouthbrooder the female carries the eggs and young in her mouth. The species is harmless to humans.
