My fish went through a pretty bad bout of fin rot a month ago and his fins just never grew back entirely. He lost half of his bottom fin to fin rot, it grew back almost completely, then it fell off again. The fin appeared to be growing back once again but the growth suddenly stopped and he started losing his scales right where this fin rot happened. At least, I think he's losing his scales. There are two identical white/somewhat patches on either side of him and they do not look like scales. The patches are getting bigger...
