Can Ocellatus Gold and Peacock Bass Ocellaris Live Together?

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

Both Ocellatus Gold and Peacock Bass Ocellaris are highly aggressive, increasing the risk of violent confrontations.

In terms of spatial distribution, Ocellatus Gold prefers the Bottom (Substrate) zone, whereas Peacock Bass Ocellaris occupies the Middle (Open Water) and Top (Surface) zones. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

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

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

The safe temperature window for both species falls between 25°C and 27°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Ocellatus Gold (8–9) and Peacock Bass Ocellaris (6.5–7.5) 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 Ocellatus Gold and Peacock Bass Ocellaris together, plan for an aquarium of at least 1500 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), Shells (Breeding/Hiding), 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.

Ocellatus Gold and Peacock Bass Ocellaris 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.
