The Ruarwe population

The Ruarwe Peacock is the Aulonocara stuartgranti population collected near Ruarwe on the western Malawian shore of Lake Malawi. Males display vivid orange-yellow to orange flanks with a metallic blue head, representing one of the Malawian west-shore colour forms of this sand-dwelling peacock cichlid. Like all stuartgranti location variants, the Ruarwe form is kept as a distinct line in the specialist hobby — crossing it with other populations is considered hybridisation.

About the species

Aulonocara stuartgranti, known in the hobby as Grant's peacock, is a maternal mouthbrooding cichlid endemic to Lake Malawi and one of the most familiar faces in the African-cichlid hobby. It is the archetypal "peacock": a sand-and-rock fish that hovers a few millimeters above the bottom and detects buried invertebrates with the enlarged lateral-line canals pitting its lower jaw — a sixth-sense feeding system confirmed in the lab on this very species. Across the lake it splits into dozens of vividly distinct geographic colour forms, from the orange-tailed Ngara "flametail" to the blue Usisya and Cobue, which is exactly why it is both beloved and a perennial hybridization headache for keepers.
