i was lucky enough to buy two pretty Mandarin drakes from my buddy Ryan. We have a nice area to the side of our yard that is shaded by a tree but also gets some sun. i have a great landscape guy ready to build me a pond. So my question is, how large and how deep should the pond be? Can it have a drop off or should it have like a beach for walk-in? My guy said he can put in a pump and fountain that should help circulate the water. But do i need some kind of filtration system? And then, how large should the enclosure be? i am estimating that i will be getting at least two ladies for the drakes, then probably one more pair. Would also love, love, love to see pics of what others have as their set up. Thanks so much for any help and suggestions.
