Can Peacock Bass Orinocensis and Trout Cichlid (Champsochromis) Live Together?

Peacock Bass Orinocensis is a semi-aggressive species (8/10), while Trout Cichlid (Champsochromis) is semi-aggressive (7/10). This modest difference means Peacock Bass Orinocensis may occasionally assert dominance over Trout Cichlid (Champsochromis).

Both Peacock Bass Orinocensis and Trout Cichlid (Champsochromis) are highly aggressive, increasing the risk of violent confrontations.

Peacock Bass Orinocensis and Trout Cichlid (Champsochromis) both frequent the Middle (Open Water) and Top (Surface) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Two territorial species may clash over territory, especially in smaller tanks.

Worth noting: Peacock Bass Orinocensis 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 Peacock Bass Orinocensis (5.5–7.5) and Trout Cichlid (Champsochromis) (7.8–8.6) 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 Peacock Bass Orinocensis and Trout Cichlid (Champsochromis) together, plan for an aquarium of at least 750 litres with a minimum length of 200 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), Driftwood (Digestion/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.

Peacock Bass Orinocensis and Trout Cichlid (Champsochromis) 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.
