TankStockingTiger Barb Tank Mates
Tiger barbs are bold, active, semi-aggressive schoolers — fun, but notorious fin-nippers that need careful tankmates.
Kept in a group of eight or more, their nipping stays directed within the school; in small groups they harass everything. The non-negotiable rule the engine enforces: never house them with long-finned or slow fish like bettas, angelfish or fancy guppies. Pair them with fast, robust tankmates instead.

Keeping Tiger Barb well: the detail
Beyond the table — the behaviour, the parameters that actually move the needle, and the mistakes that cost fish. Hobbyist context, not a verdict; the planner above is what judges your plan.
Water parameters in practice
Tiger barbs are adaptable on chemistry — pH 6–7.5, 22–26 °C — so the parameter that actually governs this fish is not water but group size. They are hardy and forgiving, which masks the real management problem: temperament. Get the social side right and the chemistry looks after itself.
Why Tiger Barb behaves the way it does
Tiger barbs are fast, bold, semi-aggressive shoalers from the streams of South-East Asia, where a large school establishes a pecking order through constant nipping and chasing. That intra-group sparring is normal and necessary — it is how they live. Take the group away and the nipping has nowhere to go but onto tankmates.
Common Tiger Barb stocking mistakes
The defining mistake is keeping too few: a handful of tiger barbs torments the whole tank, while a school of eight or more keeps the nipping internal. The non-negotiable second mistake is housing them with long-finned or slow fish — bettas, angelfish, fancy guppies — whose fins they will shred. The third is mixing them with timid species their boisterousness overwhelms.
Early signs something is wrong
Within the school, the warning sign is one barb being singled out and harried into a corner — a too-small group or too little space. Toward tankmates, watch for nipped fins on slower fish. A well-run barb school chases among itself, colours up with the rivalry, and leaves robust tankmates alone.
How tank size changes the answer
Eight is the floor and a 20-gallon long is the minimum footprint — these are active fish that need a school and room to work it out among themselves. A larger group in a longer tank is markedly calmer toward other species. Never try to soften the temperament with a smaller group; that does the opposite.

What fish can live with tiger barbs?
Fast, robust, similarly-sized fish that can shrug off the odd nip: other barbs, danios, larger active tetras, and armoured catfish like bristlenose plecos. Never keep them with bettas, angelfish, or other long-finned, slow fish.
Why do tiger barbs nip fins?
It is natural barb behaviour, made worse by small groups. A school of eight or more redirects the nipping among themselves; a handful of barbs will torment tankmates instead.
How many tiger barbs should I keep?
At least eight, and more is better. The larger the school, the calmer they are toward other fish.
