Oh, my goodness!!

Frogs have drowned their lady friends by such
behaviour.
You were able to catch the fish? I wonder if you
could hold it underwater and force the frog off to
get a breath of air.

Not sure what would cause the fish more stress
though, poor thing.

Hopefully someone will chime in with some
exerience.

If you do get the frog off I'd transport him away
from your pond to a natural waterway as he seems
to be a tad bit confused. Maybe he'll try it next with
a bass and end up as lunch instead!
