This is a friend’s koi pond. There are about 30 koi in here.

He says when he moves he’s definitely taking the fish with him. “Once you have a pond, you can’t go back.” Guess he got bit by the aquarium bug. I can see why though. The fish with the flowing water makes the backyard very tranquil. He has his maintenance routine simplified so it isn’t a lot of work. There’s a uv filter that helps keep the water clean and the algae from overtaking the place. The little machine hanging above is an automatic feeder which is set to go off twice daily. Every so often he changes the water out completely by netting the fish and washing out the pond. The thing that amazes me the most is the koi hibernate in the winter so unless it freezes, they can be left in the pond year round.
