The Mbenji Island population

Aulonocara koningsi "Mbenji Island" is the Mbenji Island population of Aulonocara koningsi, a geographic colour form from the Malawi coast of Lake Malawi in the south-central part of the lake. It is the same species as Aulonocara koningsi, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.

About the species

Aulonocara koningsi is a small peacock cichlid found nowhere on Earth but the reefs of a single offshore island in Lake Malawi. Patrick Tawil described it in 2003 and named it for Ad Konings, the field naturalist who had done more than anyone to document Malawi's sand-dwelling peacocks. Like the rest of its genus it is a quiet sand-hunter: it cruises the thin substrate between the boulders, chin lowered, listening through enlarged sensory canals for the twitch of buried invertebrates rather than searching for them by eye. The breeding males are an electric, near-uniform blue, which is exactly why the fish reached the aquarium trade as the 'Blue Regal' or 'Mbenji' peacock long before most hobbyists could spell its describer's name.
