Description

The Malawi sanddiver is a large cichlid endemic to Lake Malawi in East Africa. The species grows to about 30 cm; courting males turn bright blue with orange. It often occurs over sand in shallow areas off sandy beaches. With its mouth it takes large mouthfuls of sand, sifts out insect larvae and small crustaceans and spits the sand back out. When threatened it can bury itself in the sand. It is a maternal mouthbrooder. The species is popular with aquarists and is harmless to humans.
