What fish eat frogs?

I own a fish Hatchery and sell tadpoles. A big frog takes 2 years to become a frog from a tadpole. Te tail is poison and nothing eats tadpoles. After the tail falls off in 2 years and grows legs and becomes a frog, many things can eat the frog. Bass fish or any preditor fish. Rubber frogs are used as fish lures. Racoons eat frogs, snakes and birds.Kind of a hard life after 2 years of being a tadpole. Once 40 years ago we cut open a big frog who had eatted 3 small snapping turtles. So about anything eats frogs, but in the midwest Bass would be first preditor fish to do it.
