API® BETTAFIX fish medication is an all-natural antibacterial treatment for Betta fish and should be used whenever your Betta shows signs of illness, such as wounds, ulcers, mouth fungus, fin and tail rot, slimy patches, and cottony growths.

BETTAFIX fish medication helps heal damaged tissue from handling, netting, and fighting using the healing power of Melaleuca—a type of tea tree oil—which rapidly promotes the regrowth of damaged fins and skin.
