Hognose hasn't eaten since October 12!

[Akuma223]

The young western hog I've had since october 12th hasn't eaten since that very day. I fed him when I got back from the reptile expo, he ate overnight when I was asleep. I've tried braining mice, and scenting them with toad. I'm not used to dealing with this kind of thing at all and don't know what to do. The creature literally does nothing, doesn't explore, eat, and gets pissy on the rare occasion I try to hold him. I've tried freshkilled prey, and frozen but not live. All prey has been the perfect size for him and he still wouldn't take it. I've left this animal alone as much as possible to not stress him but he still does nothing.

He is a little less than 1ft long and currently in a small tub about 1ft 2in long, 10in wide, and around 7in tall. He is on soil,cypress,sand mix with humidity of 65. The surface temp is 82f across the board, ambient temp is 72f. He burrows under the substrate and stays there, I've only ever seen him poke his head out once. He has had fresh water available to him at all times.
