The Chiwi Rocks population

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

About the species

Labeotropheus fuelleborni, the blue mbuna, is a rock-grazing cichlid endemic to Lake Malawi and one of the most instantly recognizable members of the lake's mbuna flock. Its fleshy, overhanging snout sits above a downturned mouth packed with chisel-shaped teeth — a purpose-built rasp for scraping the algal turf, or aufwuchs, off rocks. It is also a textbook case of explosive color variation: populations differ island to island, and females come in a barred blue-grey form and a patchwork orange-blotch (OB) morph, a polymorphism that has made the genus a favorite subject for evolutionary biologists.
