Description

Trewavas's scrapermouth mbuna is a mbuna cichlid endemic to Lake Malawi in East Africa. The species grows to about 12 cm and occurs in many colour morphs; the OB females (orange-black blotched) are especially striking. Characteristic is the inferior mouth with an overhanging, knobbly upper lip, adapted to remove algae (aufwuchs) from the rocks with a scraping motion, supplemented with small crustaceans and worms. It inhabits the rocky zone of the lake. As a maternal mouthbrooder the female carries the eggs and young in her mouth. The species is popular in the aquarium and is harmless to humans.
