The Chimba population

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

About the species

Eretmodus cyanostictus, the Tanganyika clown or striped goby cichlid, is a small, stout-bodied fish endemic to Lake Tanganyika that lives where almost nothing else does: the wave-battered surge zone in the first meter or two of water along rocky shores. To survive the surf it has traded buoyancy and swimming ability for a heavy body, a reduced swim bladder, and a habit of hopping over the rocks like a marine goby. Most remarkably for a mouthbrooder, it is a monogamous biparental species in which the female and then the male each carry the brood in turn, a rare arrangement that has made it a favorite subject of behavioral research.
