The Madimba Bay population

Copadichromis trewavasae "Madimba Bay" is the Madimba Bay population of Copadichromis trewavasae, a geographic colour form from the Malawi coast of Lake Malawi in the central part of the lake. It is the same species as Copadichromis trewavasae, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Copadichromis trewavasae is a small, plankton-feeding cichlid endemic to Lake Malawi, one of the lake's many utaka and a member of the genus's mbenji group. Unlike the open-water utaka that fishermen net in huge shoals, it keeps to the rough seam where sand meets rock, and breeding males build their display bower against a boulder — a "rock kadango" rather than a sand-spawner. In the hobby it is sold under the trade name "Ivory Head Mloto" or "Mloto Likoma," which causes no end of confusion with the genuinely different Copadichromis mloto.
