The Burundi population

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

About the species

Xenotilapia ochrogenys is a small, silver, sand-dwelling cichlid of Lake Tanganyika that lives much of its life as part of a roving school over the shallow lakebed, sifting mouthfuls of sand for buried invertebrates. For a few frantic weeks each breeding season the school's drab males flush into color, stake out spawning grounds, and engage in a promiscuous free-for-all in which a single female's eggs may be fertilized by two or three different males before she takes the clutch into her mouth to brood. That maternal mouthbrooding is itself notable: the genus Xenotilapia is one of the very few cichlid lineages in which biparental and female-only brood care sit side by side on the family tree, and ochrogenys falls cleanly on the maternal side of that divide.
