Trouble with shredded betta fins...
One confirmed reason for tail bitting is frustration and stress due to water current. Even if it is minimal, bettas feel "weak" with the long fins if the current is causing them to move.
Check the water surface: if you notice a lot of water movement, consider a sponge on the intake, on the outake or even bothon your filtration system if necessary to reduce stress.
