This is a completely unique experience for the lovely fish. This is a “bottomless aquarium” and is also called as “anti-gravity aquarium.” Basically, it’s a tall pillar of water that sticks up out of a pond or tank. This German YouTuber, TChelmut, placed this bottomless aquarium in his pond to make the fish see a new world around them.

This tall pillar weighs around 110 pounds and with water, it weighs a staggering 352 pounds. The air pressure keeps the water flowing. You can see how fish enjoying in the pillar.
