All right. I realize I was wrong about the airstone and the betta tank.

BUT, now I need some reassurance. On my soon-to-be fry tank, I have the HOB filter baffled and a small airstone. There isn't too much water movement on top that I can see. If I take away the bubbler thing, will the fish really be OK? Even with the baffled HOB filter?

I am having a hard time wrapping my head around this labyrinth organ. Don't they still use thier gills?

Seriously, I don't mean to sound stupid, but maybe stupid is as stupid does...
