You'll need to shine a flashlight through the base of their tail. Get it really close so it lights up their skin. One bulge in the center is female and two bulged on either side is male. Hope this helps!
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!
