He is constantly working on making a bubble nest in the corner of the tank. Do all male bettas do this a lot, or is he really driven to start his own little betta family? I'm probably anthropomorphizing big time here, but maybe he is bored from not being able to continue with his breeding instincts and bites his tail in frustration? Or maybe I am just not feeding him enough, haha.

All males generally make bubblenests, they never know when a female is coming. My current male gave up on bubblenests though, I guess he is too busy fighting his reflection.

Like what was said before, tail biters usually bite their tail due to it being too long and/or heavy for the fish to be comfortable. Sometimes out of boredom.

My roommate says I'll die by giant turtle.

Re: Trouble with shredded betta fins...

Do you have a strong filter? If there is to much current maybe that could be causing it.

8g Fluval 1M CT Betta
125g 5 Blood parrots, 1 Green Severum, 8 Dension Barbs, 10 Yoyo Loaches, 1 RTS
75g Angelfish, 3 EBGR, 4 Siames Alage Eaters, 12 Harlequin Rasboars, 1 BN Pleco, 1 Swordtail
33g long cherry shrimp, 8 pygmy corys, 5 ottos
15g 2 GBR

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.

Good luck!
