This is actually a legitimate question. I've got two males. I've got tons of stories of my half moon male wedging himself into corners and under things, requiring rescue. My veil tail has no trouble with this. Every time I go past the tank I have to check to see if Fly is trapped somewhere. I just freed him from trying to wedge himself under a rock that really couldn't have fit my thumb. The tank has been rescaped specifically to get rid of places he can get caught in, but he still manages!
His fins are getting torn up due to his frequent scrapes with death. Even with plants, I found him wedged under my tethered banana plant once. He's convinced he has to go under ANYTHING in his tank.
Is this a betta thing, or is he a bit . . . slow.
