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

The Ruby Red Peacock is a striking Lake Malawi cichlid known for the intense red, ruby and orange tones that develop in mature males. Depending on the individual and locality, the body may show darker blue or purplish tones around the head, fins and upper flanks. Females are considerably less colourful, usually appearing silver, grey-brown or softly patterned.

Like other peacock cichlids, this species uses enlarged sensory pores in its lower jaw to detect tiny movements in the substrate. It sifts sand through its mouth, separating edible organisms from the grains before expelling the sand through the gill openings.

Ruby Red Peacocks are generally calmer than many Malawi mbuna, although males become territorial around spawning sites. Their displays involve extended fins, intensified colour and lateral posturing rather than constant aggression, making them one of the more peaceful groups of African cichlids when housed appropriately.

In the wild, they inhabit clear, alkaline Lake Malawi waters around mixtures of sand, rock and open bottom. The name “Ruby Red Peacock” is also used in the aquarium trade for selectively bred red colour forms, so appearance and exact locality can vary between specimens.

Aulonocara rubescens is native to Lake Malawi in East Africa. It is associated with the lake’s rocky and sandy shoreline habitats, where peacock cichlids search the substrate for small invertebrates.

A group or mixed Malawi setup should have at least 200 litres, with a footprint of roughly 120 × 40 cm; a larger aquarium is preferable for multiple males or a community of cichlids. Use fine, rounded sand that allows natural sifting, along with limestone or other inert rockwork arranged into caves and visual barriers. Leave open sandy areas for feeding and display, provide strong filtration and good water movement, and avoid sharp decor that could damage the fish’s mouth or fins.

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

Feed a varied diet based on high-quality cichlid pellets or granules, supplemented with small frozen or live foods such as brine shrimp, mysis and daphnia. Their natural feeding behaviour is adapted to small aquatic invertebrates found in sand, so occasional fine sinking foods are particularly suitable. Avoid making mammalian meats or excessively fatty foods part of the diet, and feed modest portions rather than allowing them to overeat.

Suitable companions include other peaceful Lake Malawi peacocks and comparatively calm haplochromine cichlids of a similar size, provided the aquarium is spacious and the fish have compatible temperaments. Avoid aggressive mbuna, highly boisterous species, very small community fish and other Aulonocara strains if breeding purity matters. Keep one male with several females where possible, as persistent male attention can otherwise place too much pressure on a single female.

Ruby Red Peacocks are maternal mouthbrooders. Provide several females for a single male and offer a flat stone or open sandy area where the male can display. The female picks up the eggs after spawning and incubates them in her mouth for around three weeks, during which time she may hide and eat very little. Fry can be raised on newly hatched brine shrimp and finely powdered foods. Avoid mixing closely related Aulonocara varieties if you want to prevent hybridisation.

Mature males are larger and far more vividly coloured, developing red, ruby-orange and often blue-toned markings with brighter fins. Females remain smaller and are generally silver, grey-brown or muted, sometimes retaining faint vertical barring.
