herons dont need a ledge, they can fly right into a pond and eat while floating and
swimming around.
herons have evolved for millions of years to be patient until the fish come back out
to eat after running for cover.

A well designed pond can easily have both plants and fish and no
netting. The sides must be vertical so the herons can't stand on the
side and eat fish.
The fish and
resident snake can hide under the benches.
