Can Leopard Cory and Telmatochromis dhonti Live Together?

Leopard Cory is a peaceful species (1/10), while Telmatochromis dhonti is semi-aggressive (8/10). This notable difference means Telmatochromis dhonti may occasionally assert dominance over Leopard Cory.

Large aggression gap (7 points) between Leopard Cory and Telmatochromis dhonti increases stress risk for the more peaceful fish.

Leopard Cory and Telmatochromis dhonti 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 Leopard Cory (6–7.5) and Telmatochromis dhonti (7.8–9) 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 Leopard Cory and Telmatochromis dhonti together, plan for an aquarium of at least 120 litres with a minimum length of 80 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), Shells (Breeding/Hiding). 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.

Leopard Cory and Telmatochromis dhonti are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
