Update: I've offered him crickets, thawed bloodworms and chopped up earthworms with my feeding tweezers. He just moves his head away. The water is about an inch and a half deep with some moss, rocks and paper towel for substrate. I put him in the water and he freaks. It's bottled water so I know that's not the problem. I kept him in my closet today because I read that you should keep them in the dark so they can get used to their surroundings. He just sits on his ball of moss and only moves around it. I picked him up to see if he would eat in my hand and he crawled all around it, which I think is a good sign because he's at least moving? At this point I'm just thinking that I'll try feeding him a few times a day, I don't really know what to do.
