is it normal for a piranha to swim at an object, then suddenly slow down, then go on their side and rub against it very quickly. im thinking it might be starting signs ti ick

It could be ich if it happens a hell of a lot. If its occasional/not often then it is probably just an itch and nothing to worry about. Flashing is what it is commonly called. Most fish may flash something to some degree.
