The Kasanga population

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

About the species

Bathybates leo is a streamlined, open-water predatory cichlid found only in Lake Tanganyika, where it hunts the silvery clupeid "sardines" that drive the lake's vast pelagic fishery. One of roughly seven members of the deepwater tribe Bathybatini, it abandons the rocky-shore world most aquarium cichlids inhabit and instead patrols the blue, oxygenated middle of the lake. It is essentially never kept by hobbyists, but it is a revealing window into how Tanganyika's cichlid radiation colonized open water that elsewhere belongs to herrings and perches.
