I totally feel your pain. I've had a ton of trouble trying to get my young pacman to eat worms as well (have posted about it in previous threads). In fact, I struggle to feed him period. Unless a cricket walks by him, he doesn't eat. I put him in a smaller enclosure to try and increase the chances of him getting the crickets, which helped, but he still takes forever to get them!

I finally had success with a bit of earthworm this week. It was really wiggling and the movement enticed him. Then I tried a second piece and no dice! He seemed kind of perplexed about the piece he did eat, I'm afraid he didn't like it.

I'm going to keep trying, I really would love to get him on a steady diet of worms. Good to know I'm not the only one with this problem. Hopefully when they grow up a little they won't be a picky!
