Can Chocolate Gourami and Jaguar Cichlid Live Together?

Chocolate Gourami is a peaceful species (2/10), while Jaguar Cichlid is highly aggressive (9/10). This notable difference means Jaguar Cichlid may occasionally assert dominance over Chocolate Gourami.

Large aggression gap (7 points) between Chocolate Gourami and Jaguar Cichlid increases stress risk for the more peaceful fish.

Chocolate Gourami and Jaguar Cichlid 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.

Additional behavioural considerations to keep in mind: Aggressive fish may bully and stress shy, slow-moving species.

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.

The pH requirements of Chocolate Gourami (4–6.5) and Jaguar Cichlid (7–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Chocolate Gourami needs 0–5 dGH while Jaguar Cichlid requires 10–20 dGH.

To house Chocolate Gourami and Jaguar Cichlid together, plan for an aquarium of at least 680 litres with a minimum length of 180 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: Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Driftwood (Digestion/Hiding), Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Jaguar Cichlid 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 low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Chocolate Gourami and Jaguar Cichlid 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.
