Auratus Cichlid (Mbuna)

Melanochromis auratus

Cichlids - African
Reviewed by Guidarium Editorial DeskUpdated April 28, 2026

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.

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.

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.

Who Auratus Cichlid (Mbuna) Is Actually For

Auratus Cichlid (Mbuna) is best for a fishkeeper who expects a species with attitude and plans the tank around that behavior and can provide a keeper who can commit to a proper group of at least 4. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Auratus Cichlid (Mbuna) like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is underestimating its social needs. A token pair or trio often behaves very differently from a real group.

Fish Similar to Auratus Cichlid (Mbuna)

Trewavas' Cichlid

Labeotropheus trewavasae

Cichlids - African
13 cm Aggressive

A distinctive, rock-dwelling Mbuna from Lake Malawi easily identified by its fleshy, overhanging snout. They use this specialized mouth to scrape algae (aufwuchs) from rocks while remaining parallel to the surface. Highly active and aggressively territorial, they require a heavily rock-scaped tank, hard alkaline water, and a strict herbivorous diet to prevent 'Malawi bloat'.

Elongatus Cichlid (Pseudotropheus Elongatus)

Chindongo elongatus

Cichlids - African
12 cm Aggressive

The Elongatus Cichlid is a highly active, slender mbuna endemic to Lake Malawi. Formerly classified as Pseudotropheus elongatus, it is notorious for being one of the most aggressive and territorial of all mbuna. They require a strictly herbivorous diet (grazing on algae/aufwuchs) and a large aquarium heavily decorated with rocks to break sightlines. Due to extreme conspecific aggression, they are best kept in harems (1 male to 4+ females) or in a carefully planned, overstocked mixed-species mbuna tank.

Chipokae Mbuna

Melanochromis chipokae

Cichlids - African
12 cm Highly Aggressive

A highly aggressive, torpedo-shaped Mbuna cichlid endemic to Lake Malawi. Known for intense sexual dimorphism, this species is extremely territorial. They require a rock-heavy setup to provide caves and break sightlines, along with hard, alkaline water. They graze on algae (Aufwuchs) and require a low-protein diet to prevent Malawi bloat.

Afra Cichlid

Cynotilapia afra

Cichlids - African
10 cm Aggressive

A highly active and aggressive Mbuna (rock-dwelling cichlid) endemic to Lake Malawi. Distinctive for their unicuspid 'dog-like' teeth, they natively feed on zooplankton in the water column but remain tied to rocky territories. They require a hard, alkaline water environment with abundant rockwork for hiding and establishing territories. Best kept in a densely stocked, carefully managed species harem or Mbuna community to disperse extreme aggression.

Demasoni Cichlid (Mbuna)

Chindongo demasoni

Cichlids - African
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.

Kenyi Cichlid

Maylandia lombardoi

Cichlids - African
13 cm Highly Aggressive

The Kenyi Cichlid is a stunning but notoriously aggressive Mbuna from Lake Malawi. They exhibit extreme sexual dimorphism: females and juveniles are pale blue with dark vertical bars, while mature males undergo a complete transformation to a vibrant golden-yellow. Due to their extreme territoriality, they must be kept in large, overstocked, rock-heavy tanks to disperse aggression, typically in a harem (one male to multiple females).
