- Size gap is too large (300 vs 7 cm): Wels Catfish will treat Tiger Barb as food.
- Your 95 L tank is below the ~20000 L this pairing really wants — crowding raises aggression.
- Keep Tiger Barb in a shoal of 6+ or it gets stressed and nippy.
- Wolf Cichlid⛔ Not recommendedAggressive · 72 cm · Hard care · 24–30 °C (75–86 °F)
- Tiger Barb and Wolf Cichlid are both territorial and at least one is outright aggressive — expect serious fighting.
- Wolf Cichlid (72 cm) is big enough to swallow the 7 cm Tiger Barb whole.
- Tiger Barb is a notorious fin-nipper — even though Wolf Cichlid is larger, an active shoal will harass its trailing fins. Only safe in a full group of 6+ with plenty of cover.
- Your 95 L tank is below the ~760 L this pairing really wants — crowding raises aggression.
- Keep Tiger Barb in a shoal of 6+ or it gets stressed and nippy.
Compatibility is computed from each species' care data — a strong starting point, not a guarantee. Individual temperament varies, so always introduce new fish slowly and watch them.
Setting up a tiger barb community tank
Give the group a stable, planted 95 L+ tank with a gentle filter, a reliable heater and plenty of cover — broken sight lines and hiding spots let mid-water and bottom dwellers keep out of each other's way. Cycle it fully and stock gradually.

How to choose the right tank mates for a tiger barb
Being semi-aggressive, tiger barb can nip or harass smaller, slower or long-finned fish — give it space, broken sight-lines and similarly robust companions. It mostly occupies the middle of the tank, so it pairs naturally with species that use the other levels.
Tiger Barb grows to about 7 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 4 cm. Match its water, too: aim for 22–28 °C (72–82 °F), pH 6–7.5 and 5–19 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.
Tiger Barb is a shoaling fish — stock a group of 6+ of its own kind first, then build compatible tank mates around them. Whatever you add, introduce new fish slowly, watch for bullying in the first days, and have a backup plan if temperaments clash.
