Nightcrawlers and just big earthworms. Bait shops will have them, some gas stations might too. Not sure about florida though. Frogs are delicate but will tolerate a little handling, only time I handle mine is if I'm moving them when I clean their tub. Just to comment on the nupital pad I should have mentioned before, if they are too young they won't have it. One of my males got his after about 2 months. I got him when he was quarter size. Some might take longer to get their pads.
