Just pushing hard on his nose/eyes. The baby girl was pushing on her own body and all over her head, including the top of it. It was actually pretty comical watching her scratch the top of her head on her back.
My BP hasn't shown any signs of shedding yet, and he shed just a couple weeks ago. The BST is 6 months old, and her's might be related to stress. I'm just concerned because I haven't noticed this behavior before, and they happened back to back.
edit: I'd like to add that the temperature in the Borneo's tank was a bit too hot, but I took care of that earlier today.
