Star Sapphire Aulonocara Care Guide - Aquarium Setup, Diet & Breeding

Star Sapphire Aulonocara are colourful peacock cichlids prized for their vivid blue, metallic and sapphire-toned markings. Mature males usually develop the strongest colour, with shimmering blue across the face and body, while the fins may show contrasting yellow, orange or darker edging depending on the line. Females are generally smaller and much less intensely coloured.

These cichlids have the rounded, laterally compressed body and pointed dorsal and anal fins typical of Aulonocara. Their sensory pores help them detect small invertebrates beneath the sandy lakebed, making them especially interesting to observe as they hover, pause and suddenly dip toward the substrate.

In nature, peacock cichlids inhabit the rocky and sandy regions of Lake Malawi. They are active, alert fish that spend much of their time searching over open sediment rather than squeezing into the tight rock crevices favoured by many mbuna.

Star Sapphire Aulonocara are territorial but are often less aggressively boisterous than many mbuna cichlids. Males become more defensive around a courtship site, while females and less dominant males may display subdued colours. Aquarium strains can differ considerably in pattern, temperament and adult size.

Aulonocara are native to Lake Malawi in East Africa. The name Star Sapphire Aulonocara is generally used in the aquarium trade for a selectively bred or locality-associated peacock cichlid form, and its exact wild species identity may vary between suppliers.

A group should be housed in an aquarium of at least 200 litres, with a footprint around 120 cm long by 40 cm wide; a larger aquarium is preferable for several males or a mixed Malawi community. Use fine sand or another smooth substrate so the fish can sift naturally, and arrange limestone or other aquarium-safe rocks into caves and broken sightlines while leaving generous open areas for swimming and courtship. Strong filtration, good oxygenation and stable, alkaline water are important, with moderate lighting that shows off the males’ colours without making the fish feel exposed. Maintain the water around 24–28°C and pH 7.6–8.6.

Up to 15 cm (6 in) in total length. Males commonly reach the larger adult size, while females are usually closer to 10–12 cm (4–4.75 in).

Offer a varied diet based on high-quality cichlid pellets and flakes formulated for omnivorous or insectivorous Malawi cichlids. Supplement these with frozen or live foods such as mysis shrimp, daphnia, brine shrimp and bloodworm in moderation. Small portions given regularly are preferable to heavy meals. Avoid making mammalian meat or other fatty foods a routine part of the diet, as these are unsuitable for their digestive system.

Suitable companions include other peaceful Lake Malawi peacocks of comparable size, calm Haplochromine cichlids and robust bottom-dwelling Synodontis catfish. Avoid mbuna, highly aggressive Malawi species, delicate community fish and other Aulonocara with very similar colour patterns if maintaining breeding lines. Do not mix them with species requiring soft, acidic water, and avoid keeping multiple brightly coloured males in a small aquarium where territorial pressure can become excessive.

Star Sapphire Aulonocara are maternal mouthbrooders. Provide a group with one mature male and several females, along with flat stones or open areas where the fish can court. The male displays around a chosen site, and after spawning the female collects the eggs in her mouth before fertilising them by taking in the male’s milt. She carries the brood for around three weeks, usually refusing food, and releases fully formed fry that can be raised on finely crushed flakes, baby brine shrimp and other appropriately sized foods.

Males are larger and develop much brighter metallic blue or sapphire colouring, often with stronger fin markings and more pointed fins. Females remain smaller and are typically silver-grey, brownish or subdued blue with less conspicuous patterning.
