So I've had Leo for a month and a half and until this weekend everything ha been going fine. Friday morning I noticed he had been floating to the top of hos tank and I figured it was swim bladder cause that happened to our gold fish a month ago. So I've been fasting him, I heated his tank up to about 80 ad lowered his water levels. The next day he started sinking so I changed his water cause I hadn't done that yet and he seemed to be improving (I gave him freeze dried blood worms the night before he got sick and I think that's what cause it. So no more of those for him!) last night he seemed to be swimming normally and was doing a lot better but then when I woke up this morning the water in his tank was orange. I do have a live java fern in there and since I had little gravel in there the roots can out so I don't know if that has anything to do with it. And I've ruled out the gravel discoloration because we've used this ravel on previous fish and it never happened there. I currently have Leo in the container I keep him in when I clean his tank (it's the tub he came in from petco) and he looks normal and is swimming fine. If anyone knows anything about either the swim bladder or the tank that could help it would be so great. Thank you!
