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

Auratus Cichlid (Mbuna) is a highly aggressive species (9/10), while Black Corydoras is peaceful (0/10). This notable difference means Auratus Cichlid (Mbuna) may occasionally assert dominance over Black Corydoras.

Large aggression gap (9 points) between Auratus Cichlid (Mbuna) and Black Corydoras increases stress risk for the more peaceful fish.

Auratus Cichlid (Mbuna) and Black 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 26°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

The pH requirements of Auratus Cichlid (Mbuna) (7.6–8.6) and Black 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.

To house Auratus Cichlid (Mbuna) and Black Corydoras together, plan for an aquarium of at least 263 litres with a minimum length of 120 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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.
