I nannied for a dentist and his wife and they had a small pond. There was one big frog and when a smaller one showed up, he ran it off. I love your pond. I could sit and watch water all day long. I nannied for an attorney and he had a beautiful Koi pond. Me and the little girl would sit out there and count the fish, and then an uncle thought the pond was unsafe and filled it in. Sad, sad, sad. You worked very hard for this oasis, enjoy it.
