The Mahale Mountains NP population

Tropheus duboisi "Mahale Mountains NP" is the Mahale Mountains NP population of Tropheus duboisi, a geographic colour form from the Tanzania coast of Lake Tanganyika in the north-central part of the lake. It is the same species as Tropheus duboisi, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Tropheus duboisi, the white-spotted cichlid, is a rock-grazing cichlid found only along the northern shores of Lake Tanganyika. It is best known for a dramatic change of dress: jet-black juveniles stippled with pale blue-white spots that later vanish, leaving slate-bodied adults crossed by a single white or yellow bar behind a bluish head. Genetic work places it apart from every other Tropheus as the deepest branch of the genus, and recent fishing pressure has pushed this narrow-range endemic onto the IUCN's Endangered list.
