Signs of hunger, stress?

UPDATE

Moved my boy from his viv to a new, 15qt tub setup today -- it's the same plastic IKEA storage tub I posted pics of earlier. The tub has been furnished with substrate, a ceramic water dish, and one low-ceiling plastic hide, situated on the warm side; he has a new heat mat, regulated by a t-stat. Temps and humidity are good, and I drilled ventilation holes into the tub to provide sufficient airflow. Again, like with his tank, I used black paper to cover the sides and back, even the lid, to minimize his stress and "visibility." As before, I have not handled him at all, except for a few minutes today when I moved him to the tub.

I also took his weight today, he has lost a couple of grams, and has gone 4 weeks w/o feeding now. This is his /first day/ in the new tub setup, I'll give him about two weeks, to see if he'll start eating now that he's housed in a more tighter and enclosed space. His next scheduled feeding is 09/16, and I still have him on a 7-day schedule. I also have f/t fuzzy rats for him ready in the freezer, upgraded from the pinky's he has been refusing, and I'm planning on scenting the room properly as well and letting his prey item thaw directly on top of his tub to see if that makes any difference. My plan now is letting him get acclimated to his tub, offer food, and make sure my husbandry stays on point.

If he still refuses to eat, the breeder has offered to take him back to get him eating again and get some weight on him but as of right now, this is how I'm going to proceed; and hopefully, my baby will de-stress and accept food.
