Description

The littletooth sandeater is a cichlid endemic to Lake Malawi in East Africa, including off Cape Maclear, Likoma and Senga Bay. The species grows to about 14 cm and has a small, specialised mouth. It lives on shallow sand and intermediate bottoms and migrates to deeper water outside the breeding season; with its mouth it sifts sand to obtain benthic invertebrates. Like most Lake Malawi cichlids it is a maternal mouthbrooder. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
