Would it be worthwhile to try moving him to a plastic container smaller than his current terrarium with a thin layer of coco coir and keeping that in a darker and quieter place for a day or so before trying to feed him again? I imagine that he must be refusing to eat due to stress. I'm just wondering if the possible benefits of moving him would outweigh the risk of stressing him further. I plan to pick up some crickets tomorrow either way. Thank you for the guidance!
