The Ubwari population

Petrochromis famula "Ubwari" is the Ubwari population of Petrochromis famula, a geographic colour form from the Democratic Republic of the Congo coast of Lake Tanganyika in the far northern part of the lake. It is the same species as Petrochromis famula, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Petrochromis famula is one of the smaller members of a genus of dedicated rock-grazing cichlids found only in Lake Tanganyika. It earns its living combing a film of algae and diatoms off boulders with brush-like pads of hinged teeth, and it survives among bigger, pushier congeners by claiming narrow crevices the giants cannot fit into. Comparatively modest in size and aggression for a Petrochromis, it is nonetheless an intensely territorial maternal mouthbrooder that demands a long tank and a high-fibre diet in captivity.
