What fish can live with Croaking 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 Croaking gourami against your own reading before you buy.

What tank mates should you avoid with Croaking gourami?

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

What size tank do Croaking 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.

Croaking gourami tank mates

A small gourami at 7 cm that produces an audible croak during spawning. Needs a quiet planted tank with surface cover and easily startled by active communities.

Best tank mates (on file)

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

Chili Rasbora Pair check
The Croaking 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 7cm Croaking gourami.
Corydoras Catfish Pair check
The Croaking 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. Corydoras Catfish swims in the bottom zone while Croaking gourami stays in the top, so the two will not crowd the same water column.
Ember Tetra Pair check
The Croaking 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 7cm Croaking gourami.
Pygmy Corydoras Pair check
The Croaking gourami profile lists Pygmy Corydoras as both safe and a recommended pairing. Pygmy Corydoras schools in groups of 6 or more, so plan room for the whole group rather than one fish.
Sparkling Gourami Pair check
The Croaking gourami profile lists Sparkling Gourami as 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.

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 Croaking 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.
Neon Tetra Open pair check
Marked risky or situational on the profile. Tank length and group size change the outcome more than a temperament label does.
Angelfish Open pair check
Angelfish reaches 20cm and is flagged predatory or as likely to eat small fish. Adult-size Croaking gourami at 7cm is inside that gape range. Both species defend territory. The pairing needs a long footprint and rockwork or planting that breaks the sightline between two defended spots. Angelfish is rated semi-aggressive, so expect chasing, fin damage, or display behaviour directed at Croaking gourami. Run the pair checker before stocking.

Fish to avoid with Croaking gourami

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

Tiger Barb See why (pair)
Tiger Barb conflicts with Croaking gourami on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.
African Cichlid See why (pair)
African Cichlid reaches 15cm and is flagged predatory. Croaking gourami at 7cm is prey-sized for it. African Cichlid needs at least 200L, far above the 80L minimum for Croaking gourami. The tank that houses one stresses the other. African Cichlid is rated aggressive and Croaking gourami is rated peaceful. No community-style planning carries that gap.
Oscar See why (pair)
Oscar reaches 35cm and is flagged predatory. Croaking gourami at 7cm is prey-sized for it. Oscar needs at least 300L, far above the 80L minimum for Croaking gourami. The tank that houses one stresses the other. Oscar is rated aggressive and Croaking gourami is rated peaceful. No community-style planning carries that gap.

Tank size and groups

Published minimum for Croaking gourami: 80L — group minimum 1 .
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.
