Hi there, it looks like shed but was he just in the water before this picture ? His snout looks wet. Also looks like a bit of dirt possibly but take a pic when he's dry, a side shot like that and one from above.
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!
