Fish Fanatic
i have an Id shark that has a hole in his top fin(maybe dorsal i dunno) he had it for some time now but it looks like it might be getting bigger. I added some stress coat hoping that might help. Ive heard mela fix is good but i have a 135 gallon tank which would cost me a lot to treat the whole tank. I also dont wanna change him into a smaller tank as i thnik it would really stress him out. Any one have any ideas? It doesnt seem to sother him as he gulps down his food fast enough.
