If I want my RES to stay in one place for any length of time (while I'm cleaning the tank, for example), I put a mirror in front of him. He'll pace the length of it eyeing the other turtle (he sometimes will stick his head around the back as if he's looking for the turtle). He'll stare at his image and "puff himself up" (stand on his four feet as high as he can), flutter at his image, and yes, I have noticed the mouth movement. He has occasionally made a like of grinding sound while doing it, and I think it's a warning to the other "turtle" to back off.
