Fish Loft

If I ever get a fishpond, I'm definitely adding one of these fish lofts.  It is basically a clear capped plastic tube, filled with water, standing off the bottom of the pond and rising out about the water.  Assuming you have curious little fishies, they would swim up the loft to enjoy the view and you could enjoy watching the fish swim around above the pond.  (Found through Teckie Diva's)
