The Hongi Island population

The Hongi Island Peacock is the Aulonocara stuartgranti population associated with Hongi Island, a small island situated in the northern portion of Lake Malawi near the main Chilumba collection area at approximately 10°21'S — close to the Tanzanian border and within a stretch of shoreline that has yielded several well-documented stuartgranti colour forms. Males display orange-yellow to orange flanks with a metallic blue head, a coloration that falls within the warm-hued northern range typical of this species, and the island's geographic isolation has produced a population whose coloration is notably consistent across individuals. The hobby has tracked this as a distinct collection line for precisely that reason: island-restricted populations of stuartgranti, cut off from gene flow with adjacent mainland forms, offer a reliability of pattern that appeals to collectors focused on location-pure cichlids.

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.
