Can Orangespotted Sunfish and Peacock Bass Temensis Live Together?

Orangespotted Sunfish is a moderately assertive species (6/10), while Peacock Bass Temensis is semi-aggressive (7/10). This modest difference means Peacock Bass Temensis may occasionally assert dominance over Orangespotted Sunfish.

Orangespotted Sunfish 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.

Worth noting: Peacock Bass Temensis is a known jumper, so a tight-fitting lid is essential.

There is no temperature overlap between Orangespotted Sunfish (10–25°C) and Peacock Bass Temensis (26–30°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–15 dGH. Regular testing will ensure conditions stay within this range.

To house Orangespotted Sunfish 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), Driftwood (Digestion/Hiding), 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.

Orangespotted Sunfish 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.
