One word about bloodworm feeding: Some humans are naturally allergic to bloodworms, so you should be a little careful about getting them on their hands. It's only a small percentage of the population, though, and it's rarely a bad allergy.
I feed my frogs live blackworms. They LOVE it. Consequently, the fish in the tank get blackworms at the same time. I just feed them late in the evening (for the frogs' sake, as I believe they are primarily nocturnal), and feed enough that everyone can get their fare share. Don't feed every day. Every other day at most should do it.
Handling the frogs isn't recommended, as they are very small and very delicate. It's easy to hurt them. Some frogs will accept being handled okay, and others will freak out. Either way, the oils on our skin isn't very healthy for them, so, if you insist on handling them, please rinse your hands off thoroughly with cool water before doing so. And be very, very gentle, because, as I said, they are SOOOO delicate.
