Nightcrawlers are by far the best staple , and if introduced early enough your pacman will love them. My two (Fatty and Houdini) go crazy for them. They easily down between 2-5 at a time, they love them, even dusted. Pinky's/Fuzzies/Mice as tempting as it is, limit to once a month. Any more than that and you risk major health issues, along with your frog growing way fast and getting way too fat.
