Any idea what kind of bivalve these are. They are sessile and have bright red and white stripes on what I would call the mantle if they were clams. They were on a 4 yo piece of live rock that came from my DT when I set up my IM Fusion 10 gal.
You can just see the stripes on the smaller one below and to the left of the one with the bristle worm on it.
