Fin Biting
•Symptoms: Not to be confused with Fin/Tail Rot, Fin or Tail biting is when a betta bites his own tail, tearing off pieces. Fins will be ragged, they will look like there are chunks missing, Fin loss can occur overnight, The tips of the fins are clean, no black or red edging, You may spot him swimming in circles, chasing his tail, There may be no other behavioral change
•Treatment:
Bettas bite their own tails out of boredom or misplaced aggression. To cure his boredom, try getting him a larger tank, move things around in the tank to spark his interest, put a mirror up to the tank a few times per day to let him exercise, offer a variety of foods, get him some tank mates (research into this first though), or put his tank next to another betta’s tank ect… Owners of fin biters often have to deal with their tendency for a lifetime but do what you can to draw his attention from his fins. When your betta does have a fin biting episode, it is important to keep his water extra clean to prevent infection. You can treat him for a few days with Aquarium Salt until you see regrowth but you do not want to overuse it. Using Stress Coat as the water conditioner will help fin regrowth.
