Last night I was staring at my tank and swore a rock moved. Watched for a while, and sure enough - there's a section of *really* live rock in there. My best guess is a kind of bivalve, since it seems to open and close like one, and reacts to light. I (gently) tried to move it with a butter knife and it wouldn't budge.
It's that whole section with the polyps on it that moves.
That's pretty cool. I once had some kind of clam that had a lot of coraline and rock grown around it so that it looked like a rock finger that opened and closed. Probably the same thing.
Haha, bet that was kind of creepy! Yeah, hard to tell from the pic, but it seems to be a type of clam. They show up sometimes on corals and live rock and are good natural filtration.

I'm hoping it's a clam or something equally cool/good for the tank. I had a small bristle worm appear out of the same rock a few days back, so this is definitely a bonus deal I think I spent a couple hours last night staring at the thing and trying to get a good picture ... after the initial creepy factor, it became a mild obsession.
