Sulphurhead Peacock, Maylandii (Aulonocara maylandi) — > 9,5cm

Overview

The Sulphurhead Peacock (Aulonocara maylandi) is a striking Lake Malawi peacock cichlid with a brilliant yellow head and elegant coloration. This beautiful species is highly sought after in the malawi peacock cichlid market, endemic to specific reef habitats including West Reef (Luwala Reef) and Eccles Reef (Chimwalani Reef) in Lake Malawi. With an adult size of approximately 14 cm, this species requires a spacious aquarium with hard, alkaline water and compatible tankmates. The Sulphurhead Peacock is prized for its vivid yellow head coloration that contrasts beautifully against a blue-grey body, making it an exceptional centerpiece for African cichlid aquariums. For experienced aquarists seeking a rare, elegant peacock cichlid that thrives in well-maintained Malawi conditions, A. maylandi delivers exceptional beauty and fascinating natural behavior.

Appearance

Aulonocara maylandi males display a brilliant sulfur-yellow head and nape that contrasts strikingly against a metallic blue-grey body. The finnage is well-developed, with males showing elongated dorsal and anal fins accented with blue, yellow, or orange highlights. Breeding males intensify their coloration dramatically, becoming even more vivid during courtship displays. Females and juveniles are more subdued, typically showing grey or pale coloration with minimal patterning. The eyes are large and expressive, often showing a bright orange or yellow rim. The overall appearance is elegant and refined, making this species a standout in any Lake Malawi aquarium.

Natural Habitat

Endemic to Lake Malawi in Malawi, Aulonocara maylandi is found exclusively at West Reef (Luwala Reef) and Eccles Reef (Chimwalani Reef). The natural habitat consists of sandy substrates near rocky reefs, where males establish territories and use their specialized sensory pores to detect invertebrates hidden in the sand. The lake's water is hard, alkaline, and exceptionally clear, with stable temperatures and high mineral content. This species is threatened by collection for the aquarium trade, making responsible sourcing and captive breeding essential for long-term conservation.

Aquarium Setup

Best kept in hard, alkaline water with excellent filtration and regular water changes. Provide open swimming space with sandy areas and scattered rockwork to replicate natural habitat. A minimum tank size of 300 litres is required to accommodate a group with proper male-to-female ratios and compatible tankmates. Strong filtration is essential, and regular partial water changes (30-40% weekly) are critical for maintaining stable parameters. Avoid overcrowding and keep with similarly peaceful to semi-aggressive Malawi cichlids to minimize stress and aggression.

Feeding

As a primarily carnivorous/insectivorous species, Aulonocara maylandi requires a varied, protein-rich diet. Feed a varied diet of quality cichlid pellets or flakes supplemented with frozen or live foods such as brine shrimp, mysis, and daphnia. Keep vegetable matter minimal and avoid heavy use of mammal-based or overly fatty foods, which can cause digestive issues. Feed moderate portions once or twice daily, ensuring all food is consumed within a few minutes.

Behaviour and Temperament

Aulonocara maylandi is peaceful to semi-aggressive, with males defending small territories and displaying to attract females. Males display and defend a spawning site, performing elaborate courtship dances. This species is less aggressive than many mbuna but should still be housed with appropriately robust tankmates. Females are less territorial and more social. In the right setup—spacious quarters, proper male-to-female ratio, and compatible tankmates—their natural behavior and social interactions are a joy to observe.

Tank Mates

House with other peaceful to semi-aggressive Malawi cichlids of similar size, non-aggressive Aulonocara species, haplochromine cichlids with similar water requirements, and robust catfish such as Synodontis species. Avoid small fish that may be bullied or eaten, highly aggressive mbuna, overly territorial cichlids, fin-nipping species, and fish requiring soft, acidic water. A well-planned Malawi peacock community offers the best results.

Breeding

Aulonocara maylandi is a maternal mouthbrooder. Males display and defend a spawning site, and the female incubates the eggs and fry in her mouth for several weeks. Provide stable water quality, rock/sand structure, and a proper male-to-female ratio (1 male to 3-4 females) to reduce harassment of breeding females. Fry are released once they are free-swimming and large enough to accept newly hatched brine shrimp immediately. Breeding success is highest in spacious aquariums with excellent water quality and minimal disturbance.
