Asf's is a african soft fur rat which is a ball pythons native food. they are sometimes hard to find but usually will make a python eat, the tuna thing has worked a few times in the past. it was something i picked up from BHB. i tossed a f/t in a ziplock with a spoon of canned tuna shook and rolled and that seemed to intrest the snake a little more with the extra scent. but for the most part if the snake is coming out at night they are usually comfortable in their surroundings. they like to hide when nervous or scared. so it seems the setup is fine. I think the biggest thing is to keep the intrest in eating up. feed in the evenings when he is more active and you can try the different methods and something might just set off a non stop eating monster. but hopefully we will get a few more ideas on here also. i hope he eats soon let us know
