I noticed what I think is a small white Conch shell on a piece of live rock today. It is no bigger than a few millimeters in length. This piece of live rock is the one I got for free because my anemone would not detach from it in the store. This rock also has a lot of stubby worm like things on it which don't seem to do much. No feathery plumes, no long wormy appendages. There are some long yellow worms on this rock also that let out their appendages and sweep for food. Some of these are visible in this photo.
