The Fulwe Rocks population

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

About the species

Cyprichromis leptosoma is a slender, schooling cichlid endemic to Lake Tanganyika, one of the so-called "sardine cichlids" that abandoned the rift lake's rocky bottom for the open water just above it. It is a maternal mouthbrooder that spawns mid-column rather than on a surface: a female releases an egg into open water, catches it in her mouth, and incubates the brood there for roughly three weeks. Males hold three-dimensional territories in the water column and display in glowing blues and yellows, while drab females shoal in their thousands above the reef.
