Auratus Cichlid (Mbuna)

Melanochromis auratus

Cichlids - African

The Auratus Cichlid is a stunning but notoriously aggressive Mbuna from Lake Malawi. They exhibit extreme sexual dimorphism. They are strictly rock-dwellers that graze on algae (aufwuchs). Due to their hyper-aggressive nature, they must be kept in species-only or carefully managed, overstocked Mbuna setups with a strict harem ratio (1 male to several females) to disperse aggression.

Auratus Cichlid (Mbuna) Care Guide Summary

The Auratus Cichlid (Mbuna), scientifically known as Melanochromis auratus, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 11 cm and have a fusiform body shape with a moderate growth rate. Classified as highly aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a high level of biological waste.

To thrive, the Auratus Cichlid (Mbuna) requires a freshwater only aquarium with a minimum volume of 200 litres and a tank length of at least 120 cm. Water temperature should be maintained between 23°C and 28°C, with a pH range of 7.68.6 and a general hardness of 1025 dGH. A moderate water flow is preferred. An aquarium test kit can help you monitor these values.

Due to its specialist needs, the Auratus Cichlid (Mbuna) is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Male and Female / Juvenile. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

Auratus Cichlid (Mbuna) Habitat Setup

When setting up an aquarium for the Auratus Cichlid (Mbuna), a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and an established tank with natural algae growth, as they depend on it as a primary food source. Keepers should note that expect substrate disturbance, so lightweight décor should be secured and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation. Browse aquarium sand substrate options to find the best fit.

Auratus Cichlid (Mbuna) Compatibility Notes

Classified as highly aggressive, the Auratus Cichlid (Mbuna) is a social species that requires the company of its own kind to thrive. When choosing tankmates, conspecific aggression can be intense, especially in smaller tanks, territorial behaviour may cause issues if hiding spots or floor space are limited, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

8 cm Highly Aggressive

A stunning but notoriously aggressive dwarf Mbuna from Lake Malawi. Known for its intense dark blue and black vertical stripes. They are strict herbivores (Aufwuchs grazers) and prone to 'Malawi Bloat' if fed high-protein diets. Due to extreme aggression toward their own kind, they require specific stocking densities.

Yellow Lab (Mbuna)

Labidochromis caeruleus

Cichlids - African

The Electric Yellow Lab is one of the most popular and widely kept African Cichlids from Lake Malawi. Classified as an Mbuna (rock-dwelling cichlid), they are famous for their vibrant yellow coloration and striking black dorsal stripes. While considered one of the most 'peaceful' Mbuna, they are still highly territorial cichlids that require hard, alkaline water, a sandy substrate for digging, and abundant rockwork to establish territories.

Peacock Cichlid (Aulonocara)

Aulonocara sp.

Cichlids - African
15 cm Semi-Aggressive

Endemic to Lake Malawi, Peacock Cichlids are highly sought after for the breathtaking colors of the males. They are benthivorous, using sensory pores on their jaws to hunt small invertebrates in the sand. While territorial, they are generally peaceful compared to their aggressive Mbuna cousins. They require hard, alkaline water and a sandy substrate to prevent gill damage while sifting.

African Jewel Cichlid

Hemichromis bimaculatus

Cichlids - African
14 cm Aggressive

A strikingly beautiful but notoriously aggressive West African riverine cichlid. Unlike the alkaline-loving Rift Lake cichlids (e.g., Mbuna), Jewel Cichlids prefer neutral, softer water parameters. They are renowned for their brilliant red breeding dress and iridescent blue spots, but also for their extreme territoriality, especially when forming pairs and spawning. They are avid diggers and will uproot most plants.

Fairy Cichlid (Brichardi)

Neolamprologus brichardi

Cichlids - African
10 cm Aggressive

An elegant but fiercely territorial Lake Tanganyika cichlid. They are famous for their complex social structure, forming massive, multi-generational colonies where older siblings help defend and raise new fry. Due to their extreme territoriality when breeding, they are best kept in a species-only tank, as they will aggressively eliminate non-colony tank mates.

Frontosa

Cyphotilapia frontosa
