They can be OK as a treat or in a pinch, but I try to offer fresh food whenever possible. You can gutload live bugs to make them more nutritious. Live bugs also provide hydration which the freeze dried bugs can't. Same argument with pellets/dry food vs fresh salads.
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!
