Fred wrote Will the frog do any harm ?

All depends on the frog. Bullfrogs are the only frog who will eat fish. They
are large, but so are Greenfrogs, who don't eat fish.
Bullfrogs have a very deep call (only the males call) and they have a
distinctive fold of skin that goes around their ear drum. Greenfrogs don't have
this fold.

At the bottom of the page there is a link that shows a picture of a Greenfrog.

If you have a bullfrog and don't want it to eat your fish you can catch it and
move it to a natural waterway.
