Can Leopard Bushfish (Ctenopoma) and Moonlight Gourami Live Together?

Leopard Bushfish (Ctenopoma) is a generally mild-mannered species (4/10), while Moonlight Gourami is generally mild-mannered (3/10). This modest difference means Leopard Bushfish (Ctenopoma) may occasionally assert dominance over Moonlight Gourami.

Leopard Bushfish (Ctenopoma) and Moonlight Gourami 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: Leopard Bushfish (Ctenopoma) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Moonlight Gourami is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 25°C and 28°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 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 Leopard Bushfish (Ctenopoma) and Moonlight Gourami together, plan for an aquarium of at least 150 litres with a minimum length of 90 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Driftwood (Digestion/Hiding), Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Moonlight Gourami is a plant destroyer, which conflicts with Leopard Bushfish (Ctenopoma)'s requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
