Stuargrandi Peacock Cichlid (Aulonocara stuartgranti) — 5-7cm

Overview

The Stuartgranti Peacock Cichlid, scientifically known as Aulonocara stuartgranti, is a brilliantly coloured African cichlid from Lake Malawi that brings stunning visual appeal and active behaviour to dedicated cichlid aquariums. Reaching up to 12cm in length, this species requires a spacious tank of at least 250 litres and thrives in hard, alkaline water conditions typical of East African rift lakes. Available for freshwater fish UK, the Stuartgranti Peacock is an excellent choice for aquarists seeking a manageable yet visually striking peacock cichlid with rewarding mouthbrooding breeding behaviour and engaging personality.

Appearance

Male Stuartgranti Peacock Cichlids are adorned with brilliant blues, yellows, oranges, and reds that intensify during courtship and territorial displays. The body is laterally compressed with a streamlined profile, and the fins are elongated with iridescent edges. The common name "flavescent peacock" refers to the yellowish coloration often displayed by this species. Females and juveniles are far more subdued, typically displaying grey, brown, or tan coloration with minimal patterning. The dramatic sexual dimorphism is one of the defining characteristics of Aulonocara species and allows keepers to easily distinguish males from females once the fish mature. Under optimal conditions and good lighting, the male's colours are truly spectacular, making this one of the most desirable peacock cichlids for sale.

Natural Habitat

Endemic to Lake Malawi in East Africa, the Stuartgranti Peacock Cichlid is found in the countries of Malawi, Mozambique, and Tanzania. In its natural habitat, this species occupies sandy areas adjacent to rocky structures, where it uses specialised sensory pits on its head to detect invertebrates buried in the sand. Lake Malawi is famous for its hard, alkaline water, high mineral content, and exceptional water clarity. The lake's stable conditions and diverse microhabitats have allowed hundreds of cichlid species to evolve, each filling a unique ecological niche. Replicating these conditions in the aquarium is essential for the health and vitality of Lake Malawi cichlids.

Aquarium Setup

A minimum tank size of 250 litres is recommended for a group of Stuartgranti Peacock Cichlids. Use a fine sand substrate to allow natural foraging behaviour, and create a rockscape with caves, overhangs, and crevices to provide territories and hiding places. Include open swimming areas and ensure the rockwork is securely placed. Filtration must be excellent to maintain pristine water quality, with weekly water changes of 25-30% recommended. Use hard, alkaline water (pH 7.5-8.6) and consider adding Malawi-specific buffering products if your tap water is too soft. Subdued lighting and a dark substrate will reduce stress and enhance the fish's natural coloration. Avoid soft-water setups, as these fish require high pH and hardness to thrive.

Feeding

Stuartgranti Peacock Cichlids are omnivores with a preference for protein-rich foods. Feed a varied diet of high-quality cichlid pellets or flakes supplemented with frozen or live foods such as brine shrimp, mysis shrimp, and daphnia. Use vegetable matter only sparingly, as an overly herbivorous diet can lead to digestive issues. Feed twice daily in small portions that can be consumed within a few minutes, and avoid overfeeding, which can lead to water quality issues and bloat—a common problem in African cichlids. A protein-rich diet will support the development of the male's vibrant colours and maintain overall health.

Behaviour

The Stuartgranti Peacock Cichlid is an active, intelligent fish that patrols its territory and interacts with tankmates. Males are territorial and will establish and defend small territories, especially during breeding. They display to attract females and engage in ritualized aggression with rival males, though serious fighting is rare if the tank is appropriately sized and structured. Females and juveniles are less territorial and often form loose groups in open areas. This species is curious and may learn to recognise its keeper, often responding eagerly at feeding time. Their lively behaviour and stunning colours make them a highlight of any Lake Malawi aquarium.

Tank Mates

Choose tankmates from other peaceful to semi-aggressive Malawi cichlids of similar size, Haplochromine cichlids, non-aggressive Synodontis catfish, and robust, similarly sized tankmates that prefer hard, alkaline water. Avoid small fish that can be eaten, very aggressive Mbuna or large territorial cichlids, soft-water community fish, and shrimp and other small invertebrates. The key to success is maintaining a well-structured tank with adequate territories and visual barriers. The Stuartgranti Peacock is not suitable for typical community tanks but thrives in a dedicated Lake Malawi setup.

Breeding

Stuartgranti Peacock Cichlids are maternal mouthbrooders, with females incubating eggs in their mouths for approximately three weeks. Males display and defend small territories, displaying intense colours to attract females. Once the female lays eggs, she immediately picks them up in her mouth and incubates them, refraining from eating during this period. Provide rockwork and multiple hiding places to reduce stress and increase breeding success. Once released, the fry are fully formed and can be raised on finely crushed flakes and newly hatched brine shrimp. Breeding Lake Malawi peacock cichlids is a rewarding experience that showcases the fascinating reproductive strategies of these fish.
