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

About the species

Diplotaxodon sp. "Macrops North" is an undescribed deep-water cichlid recorded off Nkhata Bay, in the northern half of Lake Malawi. Its trade name ties it to Diplotaxodon macrops, a described big-eyed offshore species whose name simply means "large eyes," while flagging that this northern population has not been confirmed as the same fish. Diplotaxodon macrops itself turns out to be a complex of closely related, genetically distinct forms rather than one uniform population, and "Macrops North" is one more geographically defined piece of that unresolved picture, living out its life in the dim, blue-lit depths well offshore rather than on any rocky reef.
