Can Cyprichromis Leptosoma and Leopoldi Stingray (Black Diamond) Live Together?

Cyprichromis Leptosoma is a generally mild-mannered species (3/10), while Leopoldi Stingray (Black Diamond) is moderately assertive (5/10). This modest difference means Leopoldi Stingray (Black Diamond) may occasionally assert dominance over Cyprichromis Leptosoma.

In terms of spatial distribution, Cyprichromis Leptosoma prefers the Top (Surface) and Middle (Open Water) zones, whereas Leopoldi Stingray (Black Diamond) occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Worth noting: Cyprichromis Leptosoma is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.

The pH requirements of Cyprichromis Leptosoma (8–9) and Leopoldi Stingray (Black Diamond) (6–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 8–10 dGH. Regular testing will ensure conditions stay within this range.

To house Cyprichromis Leptosoma and Leopoldi Stingray (Black Diamond) together, plan for an aquarium of at least 1135 litres with a minimum length of 240 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), Smooth Gravel (Sensitive Barbels). 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.

Cyprichromis Leptosoma and Leopoldi Stingray (Black Diamond) 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.
