Hi mx4ever,
My fish were scared of the airstone when I first put it in the tank too. They would freak out and eventually just stay away from it altogether.
To get them used to it, I had the stone in the water, but turned off for a few days. Then when it came time to turn on the bubbles, I reduced the airflow by making a small nick in the tubing. When they got used to this, I just cut off the damaged bit of the tubing so the airflow was back to normal. They now float over the bubbles after meal times and look for the bubbles when it's not turned on.
They will get used to it eventually.
Goldfish contrary to the popular myth, have long memories and can be shy of new objects or tanks for several weeks. When I first upgraded to my 125 gallon for the fish they all hovered and moved in a little ball in one corner for over two weeks. Leave the bubbles on and just give them more time. Eventually they will grow used to it.
Goldfish do however sometimes have favorite sides of the take to rest in. It's generally an area where the flow of water is slower.

My goldfish can remember me by sight.
