Well, I don't know what 'whiteness' you're seeing, but none of his fins have any whiteness to them barring the top fin's white markings. Like I said, he was in a way overcrowded tank and was taking a beating, which is why his fin's are the way they are. I've seen many a fish's fins damaged and heal without issue from it, and if you seen the tank he came from, I'm sure you'd understand more why it's nearly every fin that has some healing to do.
As for the mark on his head, when I said spot, I didn't mean it as in part of his markings, I was just referring to the placement of the wound. I'm not completely denying that it could be HITH, but I still think it could be a 'war wound' of sorts. Take my word though that I will be keeping an eye on it, and if I don't see it healing or if it begins to get worse, I will definitely be doing something about it.
