I went to feed Leo and I saw that one side of his belly is all swollen up with the scales out... but it's only on that one side and in that one area. What might this be and what can I do?
This is like out of nowhere! I've only had him a couple weeks and even though he wasn't ever friendly (i.e. throwing himself up against the glass when I come near it like the other boys learned to do in a few days) but seemed healthy. He still is swimming around and acting otherwise pretty much normal. Is it an internal bacterial infection or something else?
