One of my bettas (Alpha) is living in my 20 g planted tank with a couple snails. He’s a great community fish but the second he sees anything like a betta he goes crazy. This sometimes gets so bad he loses half of his fins. I try everything to stop him, blocking what he’s flaring at (since it’s usually a wall), different lightings, stress coat, even going in and swatting at him. He’s super healthy, especially for a petsmart betta, and has grown the longest fins out of all of my bettas, even my imported $42 Nemo. Any tips on his flaring? I think it’s the location of the tank, he’ll usually flare at a wall, even the one facing the room. He had his worst “flaring spree” a couple months ago, losing almost all of his tail, and since then he hasn’t lost anymore and they’re almost all regrown, except earlier today when I found literal pieces of his fin scattered around, looks like it’s gone all the way to the root. I know he’ll grow lots back but I hate he’s losing fins to begin with. Not fin rot, I’ll promise you that, pretty sure it’s from flaring since he’s not a tail biter, either, and flares a lot, though nowadays just a couple seconds at a time. Advice?
