I vote we call them "cranky lines" since we all know that most of the time when not related to something seriously being wrong... our beardies get them because they are cranky or unhappy about something.
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!
