Mine does an action similiar to this when he is trying to loosen his shed. It usually happens a few days before he starts shedding his beard and head, most of the time followed by some eye buldging (ewww).
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
