Can Banded Chromide and Chocolate Gourami Live Together?

Banded Chromide is a moderately assertive species (5/10), while Chocolate Gourami is peaceful (2/10). This modest difference means Banded Chromide may occasionally assert dominance over Chocolate Gourami.

Banded Chromide and Chocolate Gourami both frequent the Middle (Open Water) and Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

The safe temperature window for both species falls between 25°C and 30°C. Aim for the midpoint of this range (around 27.5°C) for optimal comfort.

The pH requirements of Banded Chromide (7.5–8.5) and Chocolate Gourami (4–6.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Banded Chromide needs 10–25 dGH while Chocolate Gourami requires 0–5 dGH.

To house Banded Chromide and Chocolate Gourami together, plan for an aquarium of at least 450 litres with a minimum length of 150 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), Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Banded Chromide is a plant destroyer, which conflicts with Chocolate Gourami's requirement for live plants. Compromise where possible or prioritise the more critical need.

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

Banded Chromide and Chocolate Gourami 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.
