About the species

Tropheops sp. "Maleri Yellow" is an undescribed mbuna documented at Namalenje Island and Nankoma Island, part of the Maleri Islands group in the west-central part of Lake Malawi. The Maleri Islands are a well-documented reef system that has yielded named colour forms across several mbuna genera, and this Tropheops is one of them, distinguished by yellow male coloration. It has never been formally described, and no authority, IUCN status, or FishBase entry should be attached to it.
