He Flipped A Fish Tank Upside Down In His Pond And The Fish Do Something Amazing

#1 Amazing Aquarium

A German koi enthusiast had a small pond in his garden, filled with fish and beautiful to look at, but it was missing something. That's when he got the idea to take a traditional aquarium outside to add to his pond ... only he put it upside down. It's called an 'upside down aquarium'. He made an amazing addition to his pond.

#2 He Attached Legs The Flipped It Over

He put his fish in the tall aquarium with just a few inches of water. Quickly, he flipped it upside down inside the pond. The aquarium had 2-inch legs attached to the top so that when flipped over, the water would flow easily. Within a short time, and after filling the tank completely, the fish began to swim around and explore.

#3 The Fish Are Free To Leave

The fish inside are free to leave because there is no floor to the aquarium. It flows directly into the pond, meaning they can swim out any time they want. But the owner says that most of the fish visit the tower each day, some lingering for hours at a time.

#4 Fish Are Coming And Going

These aquariums allow you to explore vertical space in a way that would otherwise be nearly impossible. If you look closely at the bottom of the aquarium, you can see a white fish swimming out of the aquarium and into the pond. There really is no bottom to this aquarium! The way the aquarium is set up the fish have access to leave if they desire.

#5 It Works By Using Air Pressure

How does this all work? Air pressure keeps the water in the tower from draining out into the pond below. Cool, right? The "anti-gravity aquarium" is made by filling the tank with water by hose slowly from the bottom of the aquarium to the top that sucks all the air out, causing the water to rise. The pillar of water in the tank wants to spill downward because of gravity but it can't because of air pressure. But if you were to lift off the lid, the water would suddenly spill out and into the pond.
