Aulonocara kadensis 3-4 cm | Peacock Cichlid

Overview

Aulonocara kadensis is a striking Malawi peacock cichlid offered at a juvenile size of 3-4 cm, making it a great choice for aquarists looking to grow on a colourful show fish from a young age. Like other Aulonocara, this species is prized for its elegant body shape, metallic sheen and the potential for males to develop vivid colouration as they mature. In the right aquarium, they become confident, active fish with plenty of personality.

This species is best suited to a carefully maintained African cichlid aquarium with stable water conditions, open swimming space and sandy areas for natural foraging behaviour. While juveniles are relatively understated, adult males can develop impressive colour and display behaviour, especially when kept in a well-structured tank with suitable companions. All fish are supplied with our live arrival guarantee and fast UK delivery, so you can order with confidence.

Because these are live fish, please ensure your aquarium is fully cycled and ready before purchase. Aulonocara kadensis is a good option for keepers who want a manageable peacock cichlid with classic Malawi requirements and the reward of watching a young fish mature into a standout specimen.

Care at a Glance

Origin & Natural Habitat

Aulonocara species are endemic to Lake Malawi in East Africa, one of the world’s most famous cichlid lakes. They are commonly associated with sandy areas, transitional zones and rocky edges where they can sift through substrate and hunt for small invertebrates. This natural lifestyle is important to reflect in the aquarium, as peacock cichlids are not just colourful display fish; they are active foragers that appreciate a varied environment.

Lake Malawi is alkaline, mineral-rich and highly stable, so these fish thrive in hard, well-buffered water with excellent filtration. In nature, Aulonocara often use their sensory pits to detect prey in the sand, which is why a soft sandy substrate is ideal. Although the exact locality and taxonomic status of Aulonocara kadensis may be less familiar than some of the more commonly traded peacocks, its care should follow the same Malawi peacock principles: clean water, stable parameters and a tank designed around territory and open swimming space.

Tank Setup & Water Parameters

Aulonocara kadensis should be kept in a spacious aquarium with plenty of room for swimming and a sensible amount of rockwork to break up sight lines. A sandy substrate is strongly recommended, as it allows natural foraging behaviour and reduces the risk of mouth or gill damage. Use rocks to create caves and visual barriers, but avoid overcrowding the tank, as peacocks need open areas to display and move freely.

For best results, maintain the aquarium at 24-26°C with a stable pH of 7.0-8.5 and hard, mineral-rich water. The species is tolerant of typical Malawi conditions, but like all cichlids it does best when changes are gradual and water quality is consistently high. Strong filtration and regular water changes are essential, especially in mixed cichlid tanks where waste levels can rise quickly.

A minimum tank of 250 litres is recommended for a small group or community of compatible Malawi cichlids, with larger aquariums preferred if keeping multiple males or a broader cichlid selection. Good aquascaping should include open sand patches, rock piles and some sheltered areas, while still leaving plenty of line-of-sight breaks to reduce aggression. Lighting can be moderate to bright to bring out colour, but avoid excessive glare if the fish appear shy.

When introducing new fish, rearranging some of the décor can help reduce territorial disputes. Quarantine new arrivals where possible, and acclimatise them carefully to the tank’s water chemistry. Juveniles like this 3-4 cm specimen are especially adaptable, but they still need stable conditions and a stress-free environment to grow well.

Feeding Guide

Aulonocara kadensis is an omnivorous cichlid with a natural tendency towards small invertebrates and tiny food particles picked from the substrate. In the aquarium, feed a varied diet based on high-quality cichlid pellets or granules, supplemented with frozen or live foods such as mysis, brine shrimp, daphnia and chopped krill. A good diet supports growth, colour development and overall vitality.

Feed small amounts once or twice daily, offering only what the fish can consume in a few minutes. Overfeeding should be avoided, as excess food can quickly degrade water quality and may contribute to digestive issues. While peacock cichlids are not strict herbivores, many keepers also include some spirulina-based or vegetable-containing foods to broaden the diet and support balanced nutrition.

As with many Malawi cichlids, avoid heavy reliance on fatty foods such as bloodworm, which can be too rich if used too often. A varied feeding plan is the best approach, especially for young fish that are still developing. Well-fed peacocks are more active, more colourful and generally more resilient.

Tank Mates / Compatibility

Aulonocara kadensis is generally best kept with other Malawi cichlids of similar temperament and size. Suitable tank mates include peaceful to moderately assertive species that will not outcompete it for food or harass it constantly. Because males can become territorial as they mature, it is wise to plan the stocking carefully and avoid mixing with highly aggressive Mbuna unless the aquarium is large and expertly managed.

Good companions often include other peacock cichlids, some haps of similar temperament, and robust Malawi species that prefer the same hard, alkaline water. Keep stocking levels sensible and provide enough space for each fish to establish its own area. If keeping more than one male, a larger tank with plenty of visual barriers is important to reduce conflict.

Incompatible tank mates include delicate community fish, slow-moving species, and fish that prefer soft, acidic water. Fin-nippers and very aggressive cichlids should also be avoided. As a general rule, choose tank mates that can handle the same water chemistry and have enough size and confidence to coexist without stress.
