Thanks everyone. He had a rough time a few weeks back. I think it was a combination of different things including maybe some dehydration. But he seems to be doing quite well now.
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!
