If you...
place an aquarium in the pond on its side, allowing it to fill up with water...
Then roll it over so it's upside down...
Then start lifting it up...
Until the bottom (now the top) is out of the pond and the top (now the bottom) is slightly below the waterline in the pond...
You'll have an aquarium full of water standing up out of your pond... that is the same body of water as your pond...
I've toyed with this in smaller set ups... a 10 gal in a 150 gal pond... Guppies that explore the surface commonly went in it.
It may not serve any purpose and not be worth toying with. I doubt your Dovi would ever go up in it. But if you put a potted plant on the bottom that grew up into the above surface tank, you may be able to get a colony of livebears to live in it, serving as a food/amusement source as they venture out and meet your Dovi.
Your picture of the tank on blocks on Page one made me think of it. It's basically that same set up but with the aquarium upside down.
