How much air does a bladder snail really need??

Silly question. Iíll give a bit of background first. I found a snail while performing a bio experiment on pond plants and decided to take him home. I was only recently able to ID him as a bladder snail. Iíve had him for over half a year now. He is thriving in a clear bottle (as in the kind with, yknow, a bottle neck - small opening) with gravel, pennywort, and duckweed. As a side note, the duckweed is taking up too much of the little systemís nutrients and will soon be removed. As another side note, if anyone is questioning why I wouldnít put him in my main tank at this point, itís because Iíve seen my ghost shrimp shoving their mits in ramshorn shells for food too often.
Anyways, Iíve got an upcoming project for which I have to make a mesocosm. That is, a completely closed system. Given my bladder snailís hardiness, I think the species is a good animal candidate. The mesocosm will include a substrate, conditioned water, healthy bacteria colonies, and likely pennywort as the plant. But before I seal anyone up, I wanted to get some feedback. Will a little snail give enough CO2 to keep a plant alive? And will a little plant give enough O2 to keep a snail alive?

Some varieties of snails have lungs not gills or really reduced gills. Iím not really sure having not tried it myself but it seems unlikely to work. Even if it did have gills it would be a precarious balance. One leaf dying off and causing bacteria to use up more oxygen than normal and that could be it.

Frankly if I were going to do an enclosed system Iíd use a ramshorn from your main tank; something you wonít be too upset it the experiment fails.
