There are a few ways to create a  floating or flying fish aquarium. If you would like to completely DIY then here’s how to go about it.

Step 1

Gather a few hollow blocks and place them in your Koi pond. These blocks will be used to create a stand or base for the fish tank. So you’ll need an equal number on two sides. Depending on how shallow or deep your Koi pond is, simply use one, two, or three bricks or blocks on each side.

Step 2

The blocks should reach just below the water line and match the width or length of the fish tank base so that the fish tank can sit securely on top of the bricks.

Step 3

Grab your empty fish tank, and submerge it under the water until it is completely filled and then turn it upside down to create a vacuum seal before placing it on top of the bricks.

Step 4

Leave a little room for evaporation to ensure that the vacuum seal stays intact.
