About the species

Tropheops sp. "Mbenji Blue" is an undescribed mbuna recorded from Mbenji Island, an offshore island in west-central Lake Malawi known among hobbyists for producing distinctive, tightly localised colour forms across several cichlid genera. The trade name describes the blue coloration reported in dominant males. It is one of a number of "Mbenji"-tagged forms — Copadichromis sp. "Mbenji Blue" among the utaka is another — reflecting how consistently this single island has generated its own recognisable populations. It has no authority, no publication year, no FishBase number, and no IUCN assessment.
