Corematodus ( Gr .: "Korema" = broom + "odon" = tooth) is a genus from the family of cichlids (Cichlidae) that occurs in Eastern Africa in Lake Malawi , Lake Malombes and the Upper Shire .
features
Corematodus species reach lengths of 19 to 27 cm and have an elongated body that is three times as long as it is high. The head profile is rounded, the head just as long as the body is high. The mouth is very wide. The teeth are characteristic of the genus. Both jaws have wide tooth beds made up of numerous rows of very small, closely spaced teeth. This creates a rasp-like surface with which the cichlids gnaw away the scales of other fish. The individual teeth are club-shaped and have flattened tips.
Corematodus species are silvery gray to bluish in color. A dark longitudinal stripe extends from the "nape" to the upper area of the tail peduncle. Like almost all cichlids in Lake Malawi, the Corematodus species are mouthbrooders .
