The Kisi Island population

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

About the species

Neolamprologus tetracanthus is a large, silver-spangled predator of Lake Tanganyika's sand-and-rock margins, and the fish from which the whole genus Neolamprologus takes its name. It is best known to hobbyists for its looks — rows of pearly dots laid over a tawny body, fins edged in white, black and sometimes red — and notorious among them for a temper that, once it pairs and spawns, can clear a six-foot tank. The same fish that suction-feeds snails out of their shells in the lake will, in captivity, treat most tankmates as either rivals or food.
