I usually dust insects with calcium at every meal. A light even coat by shaking the bugs gently in a small cup with some calcium does the job. I offer in small batches so they are easy to track. Once or twice a week the calcium can be replaced with a multivitamin if you want.
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!
