My male pastel recently shed. It was a BAD shed, we had a tank WAY to big and couldn't get the humidity right. After he finished his shed I switched him to a tub. The temps are right and humidity is MUCH easier to control. However today I was holding him and noticed that on his lower jaw there was still a decent hunk of old shed left. He yawns and moves his mouth occasionally but I'm not sure how to get this skin off. Is this something to be worried about? Should I get the skin off myself or raise the humidity in the tub?
