I just noticed this today, I'm not sure what it is. He's active and basking. The bump doesn't seem to be causing pain, but he does have a dusting of a black beard ( just by the ears). It's semi hard when I touch it
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!
