ODD HABITS!
my tank is 3/4 full on the botton of small rocks. my turtle, Fredo, likes to make a clearing in the middle of the tank, that is push a bunch of rocks out from the middle, and leave only one rock in the center. he then stares that lone rock down(everytime this happens a different rock is lone in the center of the clearing). Then he raises his hands and "waves" his hands across the rock, at the same time his "fingers"/nails, are moving about a thousand miles an hours, flicking the rock a thousand times with each wave of his claw across the rock. has anyone else seen this sort of behavior? what does it mean? why does he do it?
