I would try boiled, first. First at night, in his deli. Covered. If he hasn't eaten in an hour, reheat it (with hot water) and put him in his bin with it overnight.
My second and third attempts would be boiled scented with Ivory, and boiled scented with Dawn blue. Same procedure.
When you try boiled, if he doesn't eat, on your way to putting him back, hold him about an inch down his neck and jab him in the neck, not the face, with the pink and see if he strikes at it. If so, he should be pretty easy to tease feed, too.
Where are you in FL?
