Does any type of frog/toad eat fish?

Question

I wanted to know if there was an alternative of feeding frogs/toads insect and instead fish.

Answer 1

yes. My wife bought a frog aquarium with two frogs from the pet store, they eat small fish, not sure of breed or anything, I'm not that dorky.

Answer 2

bullfrogs eat many different animals, such as fish, crayfish, bugs,sometime other kinds of frogs if they are that hungry. they even eat mouse and rats and many more...  

Answer 3

Any carnivorous animal that's capable of living on both water and land can eat fish.

African frogs come to mind, except they're not capable of living on land. Bull frogs, I believe.
