Gold / Chinese barb tank mates
Gold barbs sit in a cool-leaning band that quietly rules out many warm community staples. The safer list is short and honest; the conditional list is where most popular names land, usually over temperature rather than temperament.
Common mistakeKeeping three gold barbs in a community with long-finned fish is how keepers invent targeted fin-nipping that never stops. Small barb groups redirect chaos onto angels and gouramis. Six or more in 120L-class length spreads the energy inside the school — not onto fancy fins.
