Can Cyprichromis Leptosoma and Festivum Live Together?

Cyprichromis Leptosoma is a generally mild-mannered species (3/10), while Festivum is generally mild-mannered (4/10). This modest difference means Festivum may occasionally assert dominance over Cyprichromis Leptosoma.

Cyprichromis Leptosoma and Festivum both frequent the Top (Surface) and Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

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

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Cyprichromis Leptosoma (8–9) and Festivum (5.5–7.2) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 8–12 dGH. Regular testing will ensure conditions stay within this range.

To house Cyprichromis Leptosoma and Festivum together, plan for an aquarium of at least 200 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), Driftwood (Digestion/Hiding), Plants - Floating. 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 Festivum 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.
