It's either your little guy doesn't like change or he wants his natural setup back but that will be harder to kee clean. You do have a hide for it right?
Yes, he spends all his time there, never comes out. Although he wasn't in the natural setup for long I'm not sure why he has lost interest in eating. I don't handle him and try as much as possible not to stress him out.
