The Mkanila Bay population

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

About the species

Petrotilapia pyroscelos is a rock-dwelling mbuna endemic to Lake Malawi, described in 2011 from the waters around Chizumulu Island. Like all Petrotilapia it is a thick-lipped, tricuspid-toothed aufwuchs grazer that combs the algal felt from sunlit rock, but it carries a vivid signature: breeding males have pelvic fins the color of fire, the trait that gave the species its name (Greek for 'fire leg'). A dark submarginal band running through the dorsal fin of both sexes — absent in several of its closest relatives — is the other reliable key to telling it apart in a genus where look-alike species are separated chiefly by the live coloration of their males.
