A man from Germany built by hand this incredible lookout tower for his beloved koi fish, in the middle of his garden pond. He designed it more like a vertical observation tower, instead of a standard horizontal aquarium. The structure is made with 1-centimeter-thick glass, and it is filled with water. Some call it a bottomless aquarium, while others refer to it as an anti-gravity aquarium.
Watching how these fish react to an upside down fish tank is fascinating! Up to 20 koi swim up inside the tower up to the upper lid; they seem to genuinely enjoy their unique aquarium — and they are able to swim in and out as they please, since the tank is completely open at the bottom. The fish do it all on their own!
