I'm feeling a little helpless about one of our fish right now. He smacked into the side of the tank a few days ago during a spazz-out zoom-around-the-tank fit and ever since he's been sitting down on the bottom of the tank. He can get about, but he's mostly just holding still and sometimes he's on his side and almost upside-down although he seems to be managing to stay upright most of the time. I don't think he's dying, but he's definitely injured and from the research I've been doing tonight on the web, it sounds like it's his swim bladder that is damaged.
I can't tell if he is managing to eat or if he needs to get to the top of the tank for air, though I don't think so; he's a good-sized Siamese Algae Eater (not a pleco) and quite a nice fish (we have two and they're well-behaved in the tank, minding their own business and doing their job). Most of the sites I found said that some swim bladder injuries will heal and some won't, so I guess I just wait it out and see if he either recovers or dies, but I sure wish there was something I could do. :(
Where's an emergency piscine pet vet when you need one?
