snail shell

If I have any old clam shells, unique snail shells, or cool coral skeletons laying around I like to keep them and place them near my encrusting corals to grow on. That way if I want to move a piece to a new tank or a new area in the tank I can just pick up the loose shell/coral skeleton and glue...

Hello Reefers! I am back with another request for what is this critter growing on this snail shell?
