Okay, my newest and last remaining betta is getting to be a bit of a challenge for me. He was fine at first but suffered some kind of poisoning after plastic or something leached into his tank. Fixed that problem, but his period of extreme lethargy left him constipated.. now I've delt with that too and he's -extremely- active.. too active. He sees his reflection in the sides of his tank and spends all day long pacing his tank and flaring.. today he tore one of his fins doing it. I have put pieces of non-reflective white cardstock paper (heavy paper) along the sides and he's not freaking out quite as fast but he's still just swimming up and down the sides. Occasionally he'll stop for a few seconds to rest on a broad leaf plant at the surface, take a few breaths and he's right back at it. How in the world do I calm him down? Never had this problem before. I mean it's highly entertaining for short periods but he can't live his whole life this way.. and he's been in the tank almost a week now (although before I guess he was just too sick to notice) so he should be used to it by now. I know it's also stressing him out because he's fluctuating between periods of really deep rich color and getting washed out.. more color now that the paper is up, but still not the way he should be. I've had bettas do this occasionally but not non-stop like this and the paper usually helps.
