Description

The sand-digging cichlid is a cichlid endemic to Lake Malawi in East Africa. The species grows to about 14 cm and has a streamlined body; courting males show blue tints. It is common in shallow shore zones of the lake, over wave-washed sand bottoms. As a plankton feeder it picks zooplankton from the open water column. In the breeding season the males build a structure (bower) on the sand bottom to attract females. As a maternal mouthbrooder the female carries the eggs and young in her mouth. The species is harmless to humans.
