Yes, my next door neighbor had his expensive koi visited by a heron while he was away at work :-) However, last year he had a huge frog came to visit and, over time, the goldfish disappeared, LOL. It's very small and I had a lot of fun because "my" ducks (female had a nest 2-3 neighbors down) would eat in my yard then waddle through the fence and sit in his pond for a bit before wandering back to the nest for the day. Must be nice, one stop shopping?
