The first Pacman frog I purchased from PetSmart wouldn't eat from tongs. I now, take the tongs and 'herd' the crickets toward him and he catches them when they run in front of him. He doesn't seem to mind the tongs chaseing the crickets at all. It takes more time to feed him this way, but I'm sure to see that he eats. You can dust the crickets before hand too. The dust stays on them while they run around. I wait about 10 minutes after he eats a cricket before offering another. This gives him time to 'swallow' and get ready for the next cricket.
