Alright, it's Powder this time. Something's either scratching him up, or he has something eating away at him. He doesn't have finrot. Some pieces of his fins are missing, but I thought he was tailbiting. Nothing in his tank should be doing this to him; he just has some "ruins" that maybe would only do that to him if he was scraping up against them. The thing I'm most worried about is this little cottony thing over one of his missing scales. It's hard to see, because it's white like him.
EDIT: On closer examination, it looks like that "cotton-y growth" is his scale, and it's still holding on by a hair 0__o Like I said, it's hard to tell because he's white. Something's still beating him up though, and it's only started in the past week or so. I haven't changed anything in his tank since I set it up.
