lately I've been noticing my bp's nose looks odd. it looks like his scales a 'scraped up', or have some sort of crusty build up on them, but there is no crust, they just look that way. I'm pretty sure that the reason may be the low humidity of the tank when I left him in the care of my room mate for a couple weeks, I didnt tell him that it needed to be bumped up now and then. My main concern though is if this 'scale rot' is something I have to worry about...
