Orchids & Betta Fish? Idea, need input.

I think you should find some kind of shelf to lift the orchid up, then use two like the small orchid. Set up a sponge filter, and raise the water level. The bubbles that the sponge filter send out would give a little air movement but I'm not sure how much. With the small orchids you would be able to put a top. I'm not sure how you would get a lot of airflow in there.

And don't forget when you put stones at the bottom of the tank you're going to lose water space and the levels will change.

you definitely want a filter on the tank and a heater, depending on where you live
