It's not an airstone, it sticks out of the internal filter and blows air. Also, the water level isn't actually at the very top of the tank, because of what I've learnt in preperation for the Betta I have taken the water level down by about 2cm so that it will be easily able to be at the surface of the water, and for any possible nests to not get destroyed by the lid.
If they don't have currents, I could just take the oxygen thing off, that way the water will be completely still. (Obviously not dead still that's not possible, but you know what I mean).
omg I'd love it if my LFS has a betta like yours, the way it's face is white and then the body is black amazes me! One of the prettiest that I've seen. I hope they aren't all half moons though, I don't know why I just think that they look like a show fish and not a pet. Sounds odd doesn't it? lol
