Can Auratus Cichlid (Mbuna) and Bronze Corydoras Live Together?

Auratus Cichlid (Mbuna) is a highly aggressive species (9/10), while Bronze Corydoras is peaceful (1/10). This notable difference means Auratus Cichlid (Mbuna) may occasionally assert dominance over Bronze Corydoras.

Large aggression gap (8 points) between Auratus Cichlid (Mbuna) and Bronze Corydoras increases stress risk for the more peaceful fish.

Auratus Cichlid (Mbuna) and Bronze Corydoras both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

The safe temperature window for both species falls between 23°C and 27°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Auratus Cichlid (Mbuna) (7.6–8.6) and Bronze Corydoras (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

To house Auratus Cichlid (Mbuna) and Bronze Corydoras together, plan for an aquarium of at least 240 litres with a minimum length of 120 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
