that's why AA is so great!
No need to oxygenate the water with an air stone in nearly every tank. The filter usually provides enough surface agitation to allow oxygen exchange. When a tank is over stocked, it's a goldfish tank, the heat is high during a treatment or the fish are gasping at the surface one is needed. Bettas take oxygen from the surface so too much movement isn't good for them.
