Can Adolfo Cory and Tanganyikan Clown Cichlid (Eretmodus) Live Together?

Adolfo Cory is a peaceful species (1/10), while Tanganyikan Clown Cichlid (Eretmodus) is semi-aggressive (7/10). This notable difference means Tanganyikan Clown Cichlid (Eretmodus) may occasionally assert dominance over Adolfo Cory.

Large aggression gap (6 points) between Adolfo Cory and Tanganyikan Clown Cichlid (Eretmodus) increases stress risk for the more peaceful fish.

Adolfo Cory and Tanganyikan Clown Cichlid (Eretmodus) 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 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Adolfo Cory (4–7) and Tanganyikan Clown Cichlid (Eretmodus) (8–9.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–10 dGH. Regular testing will ensure conditions stay within this range.

To house Adolfo Cory and Tanganyikan Clown Cichlid (Eretmodus) together, plan for an aquarium of at least 100 litres with a minimum length of 90 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), Leaf Litter/Blackwater, Smooth Gravel (Sensitive Barbels), 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.
