What to Do If Female Bettas Are Fin-Nipping
Separate the fish immediately.
- Identify the aggressor. Signs include chasing, nipping, flared gills or fins, circling, and stealing food.
- Remove decorations and plants that provide hiding places and make the aggressor hard to catch.
- Add aquarium salt to help heal damaged fins and reduce stress.
- Feed a high-quality diet to improve overall health and reduce aggression.
- Observe closely for signs of stress or injury; consult a veterinarian if needed.
- Increase tank size if keeping multiple bettas to reduce stress.
- Add more hiding places so fish can escape the aggressor.
- Monitor closely and remove the aggressor immediately if fighting continues.
- Consider rehoming the aggressor if aggression persists.
