Compatibility brief
Can Betta live with Tiger Barb?
Risky. This mix is commonly discouraged for typical setups.
Compatibility score
Profile confidence: medium
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
80L
Combined minimum footprint reference for these two species: about 80L (larger active fish often want more length).
Tiger barbs will relentlessly nip flowing betta fins. The betta may flare and fight back, but the usual outcome is shredded fins and a stressed fish. This fails for the same reason shops warn against barbs with fancy guppies: long fins are a moving target. Stocking more barbs to “spread aggression” does not make a long-finned betta a safe roommate.

Next steps
Concrete changes, not "research more" filler.
- •Keep the betta alone or with quiet non-nippers. Keep tiger barbs in a proper school with short-finned tank mates that enjoy the same pace.
- •Avoid keeping Tiger Barb with long-finned fish like Betta.
- •Tiger Barb should be kept in a group of at least 8 for best health and behaviour.
Try instead
- →Swap tiger barbs for cherry barbs or harlequin rasboras if you want active colour without relentless nipping.

Check each species’ mates list, size the glass, then verify the full stock in the builder. Methodology explains how verdicts are produced.
Individual fish vary in personality. Fishori uses conservative hobby rules. Observe any new introduction closely, feed thoughtfully, and keep a quarantine or backup plan. This is not veterinary advice.
