My male firebee has only eaten 1 live mouse with me since I got him 2 months ago. He has dropped from 780 to 680g and his spine is prominent. He is in a 15 qt tub (moved from a 32qt) with a 90 hotspot gradient to a 80 coolside. Humidity is 60%. When presented a frozen thawed rat, he tries to run away. He currently has one spending the night with him.

Is it a problem how much weight he has lossed? I have a booklet of all of his feedings since 70g. He was fed both live and frozen thawed and seemed like a really good eater (got to 800g in 8 months). When I got him he had only been fed live for the few months before. Should I try feeding live?
