In 2011, German YouTube user “TCHelmut” posted a video of an awesome “lookout tower” he built by himself for his beloved koi fish. He put the “tower” right in the middle of his garden pond. And by day, around 20 koi swam up inside the tower to the upper lid! Some of the fishes even hanged back to enjoy the new view in front of them!
Aquariums are usually horizontal, but this koi habitat is vertical. It is filled with water and made with 1 cm thick glass. One comment says that the fishes probably think of it as an observation tower from where they can see land. Others call it an “antigravity aquarium” or a “bottomless aquarium”. The Koi are able to swim in and out as they please since the tank is completely open at the bottom. Pretty awesome huh?
