I just want to add a little to the other guys' posts... My beardie is sometimes stubborn and will only eat if I hand feed him. He won't eat fruits/veggies unless it's by hand. And sometimes (not often) I have to feed him worms off the tongs. If his mouth is too bad, that may be why he's not eating, though. But you could try handfeeding and see how it goes!

Just be sure to dust with supplement powder! Sounds like he sorely needs it!!

Good luck!
