That's a spider right? Very nice

Have you tried dangling the F/T in front of his hide to get his attention and when he's ready to strike just hold it up for him? That's how my BP feeds. The first time i just threw it in front of him and left it there overnight and he didn't touch it. Next time I tried the "mouse dance" and it did the trick. It is also more fun feeding him that way.

Also, have you tried feeding later at night since snakes are nocturnal?
