Does A Filter Need To Provide Bubbles For The Fish To Breathe?

Does a filter need to provide bubbles for the fish to breathe?

How do fish get their oxygen?

It doesn't necessarily need to provide bubbles because you can use an air pump. Plus sometimes if there isn't alot of fish in a tank then providing oxygen isn't vital or necessarily.

As long as the water is being disturbed then gas exchange will occur. The oxygen in the air will diffuse into the water with even the slightest "rippling" of the water.

Another thread was posted this morning asking almost the same thing. My response was:

So long as the surface of the water is being distrubed (ie; ripples or waves), you don't need to add a bubbler or anything else to oxygenate the water. The primary way oxygen gets into the water is via gas exchange at the surface of the water. Ripples and waves are the best way to accomplish this, and most filters do an adequate job of making it happen. All aerators do is send bubbles up that break at the surface and create the ripples, they don't add oxygen directly.

The thread.
