Fin's Fish Guide
The Filament-finned petrochromis (Petrochromis trewavasae) is a freshwater fish of the family Cichlidae that grows up to 18 cm.
Description
Trewavas's algae cichlid is a cichlid endemic to Lake Tanganyika in East Africa. The species grows to about 18 cm and inhabits the shallow, rocky zone of the lake. It is extremely shy and is usually found in groups. With a broad, downward-facing dentition it scrapes the algal growth (aufwuchs) from the rocks; its long gut is adapted to this plant diet. As a maternal mouthbrooder the female carries the eggs and young in her mouth. Petrochromis species are strongly territorial around their grazing patches. The species is popular in the aquarium and is harmless to humans.
