I would for sure add a couple little elevated water bowls. I personally use these. https://beanfarm.com/collections/foo...t=723909738523 with https://beanfarm.com/collections/foo...t=724029079579 as well as the large water bowl on the floor.
I wouldnt smack him on the head. They generally arent fans of having the prey come at their face. They seem to really get worked up if you rub it on their tail. I just dance mine around on tongs in front of him and then kind walk walk it away and after he checks it out for about 10-15 secs to verify it is food, he will snag it. But i dont put it right infront of his face. Like i said, i will bounce it out away from him a little, then touch his tail, then pull it away and then maybe touch his back body, and then bounce it in front of him some more. You know when they are interested as Pat will slowly follow it out as im bouncing it away and then when i bring it back in, he grabs it lol. He really isnt a deathly eater. He is pretty polite and grabs it by the head and then i just pull it and shake it a little and then let go and he hangs it down and wraps it and swallows.
