Can Buccochromis rhoadesii and Peacock Bass Temensis Live Together?

Buccochromis rhoadesii is a semi-aggressive species (8/10), while Peacock Bass Temensis is semi-aggressive (7/10). This modest difference means Buccochromis rhoadesii may occasionally assert dominance over Peacock Bass Temensis.

Both Buccochromis rhoadesii and Peacock Bass Temensis are highly aggressive, increasing the risk of violent confrontations.

Buccochromis rhoadesii and Peacock Bass Temensis both frequent the 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.

Additional behavioural considerations to keep in mind: Two aggressive species housed together increases risk of fighting.

Worth noting: Peacock Bass Temensis 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 Buccochromis rhoadesii (7.8–8.6) and Peacock Bass Temensis (5.5–7.5) 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 Buccochromis rhoadesii and Peacock Bass Temensis together, plan for an aquarium of at least 3000 litres with a minimum length of 300 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.

Buccochromis rhoadesii and Peacock Bass Temensis 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.
