I tryed to take pictures but he's small and my camera isn't good enough to see it.
I don't think he is shedding, but that is the best way to explain the appearance. You can see his spine (it's not overly prominent), and the scales directly on his spine are the ones that are turning gray and falling off. The humidity is at 55%, that's the highest I can get it...I'm going to get a reptile enclosure instead of a tank this weekend...hoping that helps with the humidity. The temp is 80-85.
