So a random question to throw out to my much more experienced bp mates. Looking at my little guy I noticed he has little bits (like in one or two spots) in his heat pits. They don't appear to be lodged there and I know they aren't those little buggers. (mites) I was just wondering if it was any cause for concern or is it just something he will either wash out his own when he goes for a dip or something that may just fall out?
