About the species

Maylandia sp. "Dolphin" is an undescribed zebra-complex mbuna recorded from a cluster of reefs on the Tanzanian shore of northern Lake Malawi. It is known only by this trade name, with no formal scientific description, authority, or FishBase entry behind it. As with the great majority of Malawi's undescribed mbuna, most of what can be said about it follows from its genus rather than from study of the population itself: it is presumed to be a rock-grazing algae-eater and a maternal mouthbrooder, but its specific colouration has not been documented in any source consulted for this article.
