Care Summary
Beautiful, hardy, and active, but consistently misplaced in community tanks where they ruin everyone else's fish. Tiger barbs are not appropriate for typical community setups despite being sold as community fish. In a proper school of 8+ in a barb-specific or robust-tankmate tank, they are excellent: striking gold-and-black tiger stripes, active schooling behaviour, and genuine hardiness. Modern colour morphs (green tiger, albino, GloFish varieties) are all the same species with identical care. The honest verdict: outstanding fish for the right tank, disaster in the wrong one.
Tankmates
Notorious fin nippers. The reputation is fully deserved: tiger barbs will systematically destroy the finnage of any slow-moving or long-finned tankmate, including bettas, gouramis, angelfish, and fancy guppies. Aggression is significantly reduced when kept in proper schools of 8 or more, because the fish redirect their nipping behaviour toward each other in dominance displays rather than tankmates. Groups smaller than 8 are problematic. Compatible only with fast-moving, non-finnage tankmates: other barbs, danios, and robust bottom dwellers.
