About the species

Tropheops sp. "Black Dorsal" is an undescribed mbuna cichlid documented from the southeastern shore of Lake Malawi, at Luwala Reef and Makanjila Rocks, with a further record at Chimwalani Reef. Its trade name identifies the trait aquarists use to recognise it — a dark or solidly black dorsal fin on breeding males, set against the paler body colour typical of the genus. It has never been given a formal scientific description, and no authority, IUCN status, or FishBase entry should be attached to it.
