The Kamamba Island population

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

About the species

Ophthalmotilapia boops is one of Lake Tanganyika's "featherfin" cichlids, a velvet-black, blue-flecked rock-dweller endemic to the Tanzanian shore. Like its three congeners it pairs an algae-grazing mouth with an elaborate courtship: territorial males build sand craters on flat rocks and flag down females with vivid, tassel-tipped pelvic fins. It is rarer in the trade than its cousins and tied to a narrow stretch of coast, which makes the most prized color forms vulnerable to collection even though the species as a whole is still considered secure.
