He Flipped A Fish Tank Upside-Down In His Pond. Now Watch What The Fish Do Inside…

I’ve seen some pretty cool fish ponds but German YouTuber “TChelmut” made something that is not only amazing, it’s also great for his Koi fish! It’s called a “tower tank” which is also known as a “bottomless aquarium” or an “antigravity aquarium.” It’s basically a pillar of water encased in thick glass, with the the air pressure preventing the water from spilling down. [googlead] And don’t worry, the fish are not “trapped” in the tower. The fish are actually free to come and go as they please but I guess they like the view from inside the tower! I’ve never seen one of these before but I would love to see this in person. So very cool!
