I’ve been told to feed in a separate container which is what I do with my 7 month old ball. My snake is not aggressive at all and I’ve never been bitten, however, he has learned that what goes in his feed bin is ‘food’ so he’ll get a striking position when I take him out of it after feeding thinking that I am food. This is why I avoid feeding him in his home tank. His feed bin is just big enough for eating so he can’t explore much and I keep my room dark when I feed him so he is more comfortable. I feed him pre-killed mice and I’ve noticed that he will ignore the mouse if I just drop it in the bin. So, I hold the tail with a clothes pin and dangle it in front of his face, at which point he gladly strikes. If you feel comfortable trying a separate container for feeding again, then I would try what has always worked with my ball. It might just take some time for yours to de-stress or it could be that mine is just a fatty who will eat no matter what. But if you feel better leaving him in his home tank, then by all means do so. You know your snake better than anyone else.
