Many hobbiests enjoy the sounds of frogs and buzzing critters, while others love the beauty and variety of koi fish. There are ponds with and without waterfalls as well as rock and pebble ponds. Big ponds, little ponds and every size in-between. When it comes to ponds, the door to your own creativity is wide open. With that being said, the door to frustration can be just as easy to step into.
