Planted-tank friendly

The single most important care decision for a tiger barb is group size, and it's worth repeating because so much of the species' reputation problem stems from getting this one number wrong: keep at least six, and ideally more, rather than the two or three sometimes suggested for a small tank.

Group Size and Fin-Nipping Prevention

A group of six or more distributes natural pecking-order and chasing behavior within the shoal itself rather than directing it outward at tankmates. Keepers who add tiger barbs in twos or threes report far more fin-nipping incidents than those who stock a proper shoal size from the start, and correcting an undersized group by adding more tiger barbs often resolves existing nipping behavior within a couple of weeks.

Tank Size and Shape

A 30-gallon tank is a reasonable minimum for a proper group of six, and a long, wide footprint suits this active, fast-swimming fish considerably better than a tall, narrow tank of the same volume. Open horizontal swimming space matters more to this species than vertical height.

Water Parameters

Tiger barbs tolerate a fairly wide range (pH 6.0-7.5, temperature 72-82°F, hardness 5-19 dGH) and are genuinely hardy from a chemistry standpoint, but this shouldn't be mistaken for tolerance of ammonia or nitrite, both of which need to stay at zero regardless of the species' general hardiness reputation.

Diet

Tiger barbs are omnivores that do well on a quality flake or small pellet as a staple, supplemented with occasional live or frozen foods like bloodworms or brine shrimp. They're enthusiastic, sometimes competitive eaters, so ensuring food reaches all individuals in a large group, rather than being dominated by the fastest fish, is worth monitoring.

Choosing Tankmates

Because tiger barbs are active and occasionally nippy even in a well-sized group, tankmates should be similarly fast-moving and not have long, trailing fins that invite nipping; slow, delicate, or long-finned fish are a poor match regardless of how large the tiger barb shoal is.
