Green tree frog:

Crickets, mealworms, waxworms, grasshoppers, katydids, earth worms, rolly pollies and moths. Crickets that are store bought should be calcium dusted or gut loaded before fed to your frog. This will make your frog healthier! Crickets are the easiest because you can get them at almost any pet store! If you feed them earth worms you should put them on a light colored tray so your frog will be able to see them easier. Frogs don't have the best vision!

Fire belly toad:

Crickets, mealworms, waxworms, mosquito larvae, flies, moths, earthworms, and some people say that they can eat raw fish. If your fire belly toads color is a dull color, blood worms can be used to make their skin brighter! NEVERfeed butterflies, grasshoppers, or fire flies (lightning bugs) to fire bellies. These can kill your toad!

American toad:

Crickets, grasshoppers, locusts, slugs, snails, earthworms, and rolly pollies.

Dart poision frog:

Termites and ants. Other then this I'm not sure what they eat.

Cuban tree frog:

Crickets and cockroaches. Cuban tree frogs may also eat other frogs including their own species. So it's safest to only keep ONE of these guys in an enclosure.

Whites tree frog (dumpy frog):

Crickets, mealworms, waxworms, moths, locusts, roaches.

Narrowmouth toad: Only ants. Beleive it or not!

Pac man frog (Argentine horned frog): Mice, and crickets.
