Red Shoulder Peacock Care Guide - Aquarium Setup, Diet & Breeding

Red Shoulder Peacocks are brightly coloured African peacock cichlids admired for the contrast between a blue head and body and the warm red, orange or copper tones across the shoulder and upper flank. Colour intensity varies with locality, lineage, age and mood, and males are generally far more vivid than females.

These fish belong to the genus Aulonocara, a group of comparatively peaceful haplochromine cichlids from Lake Malawi. They are active, alert fish that spend much of their time inspecting open areas and searching the substrate for small invertebrates.

In the wild, peacock cichlids live around sandy bottoms, rock edges and transitional zones where scattered cover meets open foraging ground. Their specialised sensory pores help them detect prey movements beneath the sand, an adaptation that gives the group its distinctive hunting behaviour.

Although less aggressively territorial than many Malawi mbuna, mature males still defend display and spawning areas. Females and younger fish are more subdued, often showing silvery, grey-brown or barred colouration rather than the brilliant adult male pattern.

Red Shoulder Peacock is a trade name used for Aulonocara from Lake Malawi in East Africa, particularly red-shouldered forms associated with the lake’s rocky and sandy habitats. The name may be applied to closely related or selectively bred Aulonocara strains, so the exact collection locality is not always clear from aquarium listings.

Allow at least 200 litres for a small harem, with a larger aquarium of around 300 litres or more preferable for a community group. A footprint of approximately 120 × 45 cm is a useful minimum guideline, while longer tanks provide better space for territories and females to avoid persistent attention. Use fine sand or another smooth substrate, arrange limestone or aquarium-safe rock into caves and broken sightlines, and leave broad open areas for foraging and swimming. Strong filtration, good oxygenation and stable, alkaline mineral-rich water are important.

Males can reach about 15 cm (6 inches) in length, while females are usually smaller at around 10–12 cm (4–4.7 inches).

Offer a varied diet based on quality cichlid pellets or granules, supplemented with flakes and occasional frozen or live foods such as brine shrimp, mysis and finely chopped aquatic invertebrates. Their natural feeding style is associated with sifting sandy habitats for tiny prey, so small sinking foods are especially suitable. Avoid making mammalian meat or heavily fatty foods a regular part of the diet, and feed modest portions once or twice daily.

Red Shoulder Peacocks can share a spacious Malawi community aquarium with similarly sized, relatively peaceful peacock cichlids and other gentle haps, provided there is adequate territory and the fish are not hybrids with unusually aggressive behaviour. Suitable companions may include peaceful Copadichromis and selected Placidochromis species. Avoid mbuna known for intense aggression, highly territorial Malawi cichlids, fish small enough to be swallowed, and South American community fish that require markedly different water conditions. Keep only one male of a particular colour strain unless the aquarium is very large and carefully structured.

Red Shoulder Peacocks are maternal mouthbrooders. Keep one mature male with several females and provide flat stones or other open spawning surfaces. After courtship and egg deposition, the female picks up the eggs and fertilises them by taking sperm from the male’s egg spots. She incubates the brood in her mouth for around three weeks, usually eating little during this time, and releases free-swimming fry that can be fed newly hatched brine shrimp and finely powdered food. Separate the female or provide dense cover if the fry need protection from other tankmates.

Males are substantially more colourful, typically developing blue facial and body tones with a red, orange or copper shoulder and iridescent fins. Females are smaller and remain mostly silver, grey-brown or subdued with darker vertical markings; mature males may also have more extended fins and egg spots.
