Thanks for your response. I put a heating pad under one corner of the container. I also got a few crickets for him. He ate a couple the first day, but has acted disinterested for the past couple of days. He seemed to be doing pretty well the first couple of days, but seems to have taken a turn for the worse. He hasn't moved much today, and his breathing has slowed. I guess only time will tell at this point, but at least I have prevented his having a gruesome death.
