My poor Lewis... I wish he was a little smarter. This guy likes to explore his tank, and while doing so, he squeezes into spots he shouldn't be. About a week ago, I woke up to find a large chunk of his tail missing, and a hole in the middle. I've been doing every other day water changes + extra Stress coat to try and aid in the healing, but yesterday he managed to rip even more of his tail out. I'm not sure how he's doing this since there isn't anything sharp in his tank. The only thing I thought could be doing this was his plastic leaf bed, which I removed as soon as I saw his tail. Otherwise, all he has in his tank is a piece of driftwood, real plants, and some smooth rocks. He likes to squeeze himself into one of the corners where it's very dark, but it's a tight spot. I'm thinking he's ripping it against the substrate maybe when he's wiggling himself in there, even though I don't think it's sharp enough. This is what I'm using (http://www.amazon.com/Flourite-7-kg...&qid=1437566988&sr=8-1&keywords=fish+flourite). I have this same substrate in my other betta tank (he has even longer/fuller fins) and I have yet to have a problem with it. I got him a betta log and am trying to encourage him to sleep in there versus on the ground, but as far as I'm concerned, he's going to continue injuring himself. I haven't seen any part of his tail begin to grow, but I don't see any infection either. There's no signs of fin rot, so that's good. I can't deal with that again. I just don't want him to continue ripping up his tail though, and am not sure really how to prevent it. Should I consider removing his substrate and replacing it with sand maybe? I don't know what to do in this kind of situation. Heck, he might even be tail biting for all I know, though I've never witnessed it. I need to figure this out though because I am moving in a month, so my family will be caring for my fish while I'm away. I've got to get him healed and well before then, otherwise he could get worse. What should I do with my clumsy Lewis?
