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

The Eureka Red Peacock is a striking aquarium colour form of Aulonocara jacobfreibergi, developed for its vivid red-orange body and contrasting blue facial, dorsal or fin markings. Adult males are especially colourful, while females and juveniles are generally more subdued, often showing silvery beige or brown tones with darker patterning.

Like other peacock cichlids, this fish combines a relatively peaceful temperament with the confident, alert behaviour typical of Lake Malawi cichlids. Males display around rocks and defend small territories, particularly when courting, but they are usually less relentlessly aggressive than many mbuna.

In the wild, Aulonocara jacobfreibergi searches across sandy areas and rocky margins for small invertebrates hidden in the substrate. Special sensory pores along the lower jaw help peacock cichlids detect prey beneath the surface, giving them a distinctive habit of pausing and sifting carefully through the lakebed.

The Eureka Red form is not a naturally occurring wild population but an aquarium-bred strain. Its bright coloration can vary between individuals and develops most strongly in mature males, especially when they are displaying or establishing territory.

Eureka Red Peacock is a selectively bred colour form of Aulonocara jacobfreibergi, a species native to Lake Malawi in East Africa. The wild species is associated particularly with rocky habitats around the lake’s southern and central regions, including areas around Cape Kaiser and Otter Point.

A practical minimum is about 200 litres for a small harem, with a tank at least 120 cm long; a larger aquarium is strongly preferred when keeping several males or a mixed Malawi community. Use open swimming space alongside piles of smooth rocks that create caves, sight breaks and individual territories. A sandy or fine-grained substrate is ideal because these cichlids naturally investigate the lakebed, and robust plants are optional rather than essential. Strong filtration, good oxygenation and stable, mineral-rich alkaline water are important.

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

Offer a varied omnivorous diet based on a high-quality cichlid pellet or flake, supplemented with spirulina, algae-based foods and occasional frozen or live treats such as mysis shrimp, brine shrimp and daphnia. Small, regular meals suit their natural foraging behaviour. Avoid making rich mammalian foods or excessive fatty protein a part of the diet, as these are poorly suited to Malawi cichlids and can contribute to digestive problems.

Suitable companions include other comparatively peaceful Lake Malawi peacocks, Utaka species and robust, similarly sized Malawi cichlids with compatible water requirements. Avoid combining them with highly aggressive mbuna, very timid fish, fin-nippers or species too small to defend themselves. Keeping multiple Aulonocara varieties together can also result in hybridisation, so separate species or clearly distinct breeding groups are preferable. A single male with several females is generally less problematic than keeping rival males in a modest-sized aquarium.

Eureka Red Peacocks are maternal mouthbrooders. Use one mature male with several females, provide caves or flat rocks for courtship, and condition the fish with a varied, nutritious diet. After spawning, the female carries the fertilised eggs and fry in her mouth for around three weeks. She may release free-swimming young among the rocks, where they can be fed finely crushed flakes, powdered fry food or newly hatched brine shrimp. To protect the brood, the holding female can be moved to a separate aquarium, although handling her should be kept to a minimum.

Mature males are considerably more colourful, commonly showing a red-orange body with blue on the face, fins or upper body. Females remain smaller and are usually silver, beige or brown with less intense patterning; males may also develop longer, more pointed dorsal and anal fins.
