Can Betta Fish Live With Rosy Barb?
No, rosy barbs are active schooling fish that need 64-72F water, which is too cool for bettas, and they may nip betta fins.
Why
- Rosy barbs need 64-72F water while bettas need 76-82F. There is no overlap, so one species suffers regardless of tank setup.
- Rosy barbs grow 3-4 inches and are active swimmers that can stress slow-moving bettas.
- Barbs are known fin-nippers. Betta fins trigger this behavior in active barb species.
- Bettas are slow, ornate fish that cannot escape fast-moving barbs in a community tank.
- Rosy barbs need schools of 6+ and need 30 gallons minimum, complicating any attempt at compatibility.
What could go wrong
Rosy barbs will nip betta fins while the betta suffers from cooler water, leading to injury and stress in both species.

Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.
Better pairings to consider
Bettas do well with peaceful fish like corydoras or small tetras in heated tanks. Rosy barbs do well with white cloud mountain minnows or coolwater corydoras in unheated tanks.
