The Luwala Reef population

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

About the species

Melanochromis heterochromis is a rock-dwelling mbuna documented from a cluster of islands and reefs in the southern part of Lake Malawi, including Mumbo Island, Domwe-adjacent Zimbawe Rock and the twin islands of Chinyamwezi and Chinyankwazi. Its species name, from the Greek for 'different colour,' places it in a genus long recognised for exactly that trait: Melanochromis is the mbuna group whose horizontal-striped pattern and pronounced male-female colour divergence stand apart from the vertically barred zebra-type cichlids that dominate much of the lake's rocky shoreline.
