Can Betta Fish Live With Zebra Danio?
No, zebra danios are fast active swimmers that stress bettas and may nip at long flowing fins.
Why
- Zebra danios reach 2 inches and swim in active schools at mid-levels, occupying space a betta defends.
- Zebra danios are constant swimmers. A betta sees unpredictable movement near its territory as a threat.
- Danios may nip at betta fins. Long flowing fins look like food or targets to an active schooling fish.
- Bettas prefer still water near the surface. Danios need open swimming space in the mid-column.
What could go wrong
Zebra danios nip betta fins during the day or stress the betta into hiding, while the betta may lunge at passing danios.

Better pairings to consider
Zebra danios do well with barbs or larger tetras in an active community tank. Bettas do well with corydoras or mystery snails.
