Betta vases are dangerous for so many reasons. The most obvious is the

case of a lily vase, it's just a matter of time before the oxygen level
drops and Betta literally drowns. All aggressive jumping in the world
isn't going to allow them to reach the surface of the water in the vase
shown in the link.

If you've kept bettas and watched them get stuck you'd know how hard they
try to get air. If there's even a tiny opening in the water surface
they'll find and use it. You might be surpeise how strong they are.

Also, this is not a complete ecosystem. I don't care how shallow a rice
paddy gets, it is still part of a complete ecosystem fed by a larger
body of water.

They have found in depressions as small as heelprints in the mud.

Nitrofying bacteria cannot establish themselves in a
vase. Aquatic plants can reduce nitrate in the water but it will not do
enough to remove toxic ammonia. In fact, being terrestrial, Peace
Lilies will contribute to the ammonia build up when it deteriorates in
the water... as Elaine said.

Plants primarily consume ammonia. THey have to reduce nitrate to
ammonia to use it (except crytps which can use nitrate directly)

There are also feeding issues and water parameter stability issues that
need to be addressed as well. There are so many reasons why a Betta
vase is bad I can't even begin to guess why folks wouldn't emmediately
denounce their use.

The only question I have is can there be enough microbials life
on the roots to sustain the betta. Bettas eat quite a bit, but whatever
the answer is I would not be surprised.
