about a week ago i noticed a bump on my brevis that looks like a zit. sometimes it looks more angry than others. it is on the side of him where he'd be rubbing against the shell. I thought maybe it was like a blister but since it doesn't seem to go away i'm worried it could be a parasite or some such. anyone know what this is and what i can do about it? i'm quite fond of him and his fry need a papa! thanks in advance!
