Overview
Hybrid between Aulonocara and OB mbuna (usually Melanochromis auratus female). Orange-black blotched body with peacock-blue overtones. Hugely popular in the trade despite hybrid origin.
Appearance
Shared with the species: Peacock Cichlid
Elongated, moderately deep body reaching 10–15 cm. Small, slightly downturned mouth evolved for sieving sand. Males: brilliant metallic coloration varying by species — blue, yellow, orange, red, or multicolor with metallic shimmer. Females: plain brown/gray camouflage pattern.
Care
Shared with the species: Peacock Cichlid
Malawi cichlid setup 200+ L. Temperature 24–28°C, pH 7.8–8.5, GH 10+. Fine sand substrate essential — they sift it for food. Rockwork for shelter plus open sandy areas. Keep one male Aulonocara species per tank.
Feeding
Shared with the species: Peacock Cichlid
Omnivore: sifts invertebrates from sand in the wild. Tank diet: quality cichlid pellets, frozen/live bloodworm, brine shrimp, cyclops, daphnia. Avoid high vegetable diets (they are more carnivorous than mbuna).
Compatibility
Shared with the species: Peacock Cichlid
Moderately aggressive. Best with other moderate Malawi haplochromides (not mbuna). Multiple male Aulonocara of different species can coexist in large tanks.
Breeding
Shared with the species: Peacock Cichlid
Maternal mouthbrooder. Male displays bright colors to attract female; she deposits eggs and picks them up immediately. Broods 20–40 eggs for 21–28 days. Fry are released large and independent.
Fun facts
Shared with the species: Peacock Cichlid
Aulonocara detect invertebrates buried in sand via enlarged sensory pores (neuromasts) on the lower jaw — a unique feeding adaptation. The name 'peacock' refers to the spectacular tail-spread-like display of males.
