Platy-should I Be Concerned?

[corey01]

one of my platies seems to be quickly rubbing itself on one of my plant leaves. its shows no sign of gill flukes or parasits on the scales but still im worried. 2 of my other fish were doing the same 2 monthsd ago but after a while they stopped. my water stats are fine so im not really sure what to do!?
