If you recently introduced the plant, then the fish may be unsure or fearful of it. Just as you wouldn't turn your back to someone you don't trust, the goldfish does not want to make itself vulnerable. Chances are that the fish will eventually not feel threatened by the plant and will be comfortable swimming over it.
They may be afraid of the plant. My goldfish was the same, try moving it.

They might be happy. Or they aren't used to the tank yet. Goldfish also lose their memory every 3sec. (or so I am told) The fish might jut be discovering his tank/bowl over and over and over again
