Tiger barbs are striking, energetic fish with a reputation — deserved — for nipping the fins of slower tank mates. But that behaviour is manageable, and the secret is simple: keep them in a big enough group. Kept right, a shoal of tiger barbs is one of the most active, entertaining displays in the hobby. This UK guide covers tiger barb care.

Here’s how to keep them without the drama.

Quick facts

• Adult size: 6–7 cm
• Tank size: 90 litres for a group of 8+
• Water: pH 6.0–7.5, 22–26 °C
• Lifespan: 5–6 years
• Temperament: active, semi-aggressive, nippy

The fin-nipping fix: bigger groups

Tiger barbs establish a pecking order among themselves. In small numbers they take their aggression out on other fish; in a group of eight or more they mostly squabble amongst themselves, leaving tank mates alone. This single change is the difference between a peaceful tank and a bullied one.

Tank setup and feeding

Give them a 90-litre-plus tank with open swimming space and some planting. They are hardy and undemanding — feed a varied diet of quality flake and frozen foods. See best fish food.

Tank mates to choose and avoid

Avoid long-finned, slow fish — bettas, angelfish, guppies and gouramis are prime nipping targets. Good matches are other fast, robust fish: danios, larger tetras, plecos and corydoras.

Frequently asked questions

Why do tiger barbs nip fins?

They establish a pecking order, and in small groups they direct that aggression at other fish. Keeping eight or more keeps their squabbling within the shoal, leaving tank mates alone.

How many tiger barbs should be kept together?

At least eight. Larger groups spread out their natural aggression and dramatically reduce fin-nipping of other species.

What fish can live with tiger barbs?

Fast, robust fish like danios, larger tetras, plecos and corydoras. Avoid long-finned, slow-moving fish such as bettas, angelfish, guppies and gouramis.
