What fish can live with Chocolate gourami?

Use the "Often compatible" lists as a shortlist, not a stocking plan. Always run the pair tool and check the footprint of your actual tank first. Verify behaviour for Chocolate gourami against your own reading before you buy.

What tank mates should you avoid with Chocolate gourami?

Avoid Tiger Barb, Oscar, African Cichlid based on size, temperament, or predation risk on file.

What size tank do Chocolate gourami need for a community?

80L is the planning floor for adult swimming space and bioload headroom. Long-term, a 98L+ tank lets adults use the full footprint without crowding the next species. Footprint, meaning length and front-to-back depth, matters as much as raw volume for active or territorial species.

Best tank mates (on file)

Merged from conservative safest and best with fields — de-duplicated by species.

Amano Shrimp Pair check
The Chocolate gourami profile lists Amano Shrimp as a recommended pairing. Water parameters barely overlap between the two, so check the temperature and pH ranges on both profiles before stocking.
Chili Rasbora Pair check
The Chocolate gourami profile lists Chili Rasbora as both safe and a recommended pairing. Chili Rasbora schools in groups of 8 or more, so plan room for the whole group rather than one fish. Chili Rasbora grows to about 2cm, which is borderline mouth-size for an adult 5cm Chocolate gourami.
Corydoras Catfish Pair check
The Chocolate gourami profile lists Corydoras Catfish as both safe and a recommended pairing. Corydoras Catfish schools in groups of 6 or more, so plan room for the whole group rather than one fish. Water parameters barely overlap between the two, so check the temperature and pH ranges on both profiles before stocking.
Ember Tetra Pair check
The Chocolate gourami profile lists Ember Tetra as both safe and a recommended pairing. Ember Tetra schools in groups of 8 or more, so plan room for the whole group rather than one fish. Ember Tetra grows to about 2cm, which is borderline mouth-size for an adult 5cm Chocolate gourami.
Sparkling Gourami Pair check
The Chocolate gourami profile lists Sparkling Gourami as both safe and a recommended pairing. Sparkling Gourami schools in groups of 6 or more, so plan room for the whole group rather than one fish.

Risky or situational

From risky tank mates and broad avoid with (excluding “unsafe” below). May work with species-only setups, more water, or mature systems — read the pair page.

Dwarf Gourami Open pair check
Both species defend territory. The pairing needs a long footprint and rockwork or planting that breaks the sightline between two defended spots. Run the pair checker before stocking.
Betta Open pair check
Both species defend territory. The pairing needs a long footprint and rockwork or planting that breaks the sightline between two defended spots. Betta is rated semi-aggressive, so expect chasing, fin damage, or display behaviour directed at Chocolate gourami. Run the pair checker before stocking.
German Blue Ram Open pair check
Both species defend territory. The pairing needs a long footprint and rockwork or planting that breaks the sightline between two defended spots. Run the pair checker before stocking.
Bala / silver shark Open pair check
Bala / silver shark reaches 35cm and is flagged predatory or as likely to eat small fish. Adult-size Chocolate gourami at 5cm is inside that gape range. Run the pair checker before stocking.

Fish to avoid with Chocolate gourami

From the unsafe list — predation, aggression, or space rules on this profile.

Tiger Barb See why (pair)
Tiger Barb conflicts with Chocolate gourami on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.
Oscar See why (pair)
Oscar reaches 35cm and is flagged predatory. Chocolate gourami at 5cm is prey-sized for it. Oscar needs at least 300L, far above the 80L minimum for Chocolate gourami. The tank that houses one stresses the other. Oscar is rated aggressive and Chocolate gourami is rated peaceful. No community-style planning carries that gap.
African Cichlid See why (pair)
African Cichlid reaches 15cm and is flagged predatory. Chocolate gourami at 5cm is prey-sized for it. African Cichlid needs at least 200L, far above the 80L minimum for Chocolate gourami. The tank that houses one stresses the other. African Cichlid is rated aggressive and Chocolate gourami is rated peaceful. No community-style planning carries that gap.

Tank size and groups

Published minimum for Chocolate gourami: 80L — group minimum 4 (schooling).
Compatibility changes when the tank is too short for turning, too little for a real school, or too warm for one species and not the other — that is why pair checks include tank context, not only temperament.
Nearest litre hub to this minimum: 80L hub.

Easier alternatives to consider

Conservative beginner-peaceful picks from the library — not replacements for reading, but a shorter on-ramp than this species for a first tank.
