Thanks so much! I'll definitely try your substrate trick. What is the best time to do something like that? Do I wait until he's ready to be handled and do it while he's out of the bin, or do I replace the substrate with him in there? If the latter, should I do it at night so I don't wake him up, or during the day so he stays in his hide the whole time?

Thanks for letting the newb pester you with questions!
