Ok so I've had this piece of live rock in my tank for about 7 months now and about a month ago I noticed this thing moves. More like opens and closes like a clam but it opens on the side that's against the rock. Anyone have a clue? It's right in the middle and looks like a curled tongue or something. Idk
