What fish can live with Gold / Chinese barb?

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 Gold / Chinese barb against your own reading before you buy.

What tank mates should you avoid with Gold / Chinese barb?

Avoid Oscar, African Cichlid, Green Terror based on size, temperament, or predation risk on file.

What size tank do Gold / Chinese barb need for a community?

120L is the planning floor for adult swimming space and bioload headroom. Long-term, a 146L+ 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.

Boesemani Rainbowfish Pair check
The Gold / Chinese barb profile lists Boesemani Rainbowfish as both safe and a recommended pairing. Boesemani Rainbowfish 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.
Corydoras Catfish Pair check
The Gold / Chinese barb 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.
Dwarf Gourami Pair check
The Gold / Chinese barb profile lists Dwarf Gourami as both safe and a recommended pairing. Water parameters barely overlap between the two, so check the temperature and pH ranges on both profiles before stocking.
Neon Tetra Pair check
The Gold / Chinese barb profile lists Neon Tetra as both safe and a recommended pairing. Neon Tetra 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.

Tiger Barb Open pair check
Tiger Barb is flagged as a fin-nipper and Gold / Chinese barb carries the long-finned risk profile (veil tails, trailing fins). Expect torn fins within days unless the nipper is in a proper group and the long-finned fish has plenty of cover. Tiger Barb is rated semi-aggressive, so expect chasing, fin damage, or display behaviour directed at Gold / Chinese barb. Run the pair checker before stocking.
Angelfish Open pair check
Angelfish reaches 20cm and is flagged predatory or as likely to eat small fish. Adult-size Gold / Chinese barb at 7cm is inside that gape range. Angelfish is rated semi-aggressive, so expect chasing, fin damage, or display behaviour directed at Gold / Chinese barb. Temperature ranges barely overlap between the two, so one species ends up living at the edge of its comfort window. Run the pair checker before stocking.
Giant danio Open pair check
Giant danio reaches 11cm and is flagged predatory or as likely to eat small fish. Adult-size Gold / Chinese barb at 7cm is inside that gape range. Run the pair checker before stocking.
Pea Puffer Open pair check
Pea Puffer is flagged as a fin-nipper and Gold / Chinese barb carries the long-finned risk profile (veil tails, trailing fins). Expect torn fins within days unless the nipper is in a proper group and the long-finned fish has plenty of cover. Pea Puffer is flagged predatory. Equal-size adults usually coexist, but the moment one is stressed, sick, or smaller after a moult, it becomes prey. Pea Puffer is rated semi-aggressive, so expect chasing, fin damage, or display behaviour directed at Gold / Chinese barb. Temperature ranges barely overlap between the two, so one species ends up living at the edge of its comfort window. Run the pair checker before stocking.
