Intelligent worm!

Discovered this all grey worm - it is about 1-2 inches long and very quick. It sort of does what a bristle worm does - keep part of its body under a rock or a coral stretches out and then darts back but here is the difference. It is building a little den or what ever you would call it for a worm. On two occasions it has stretched out and gotton a small piece of crushed coral and taken it back to where it is presumably building this little den or something to that effect. It also has atennae on it's face unlike the 1/4 pink 3/4 grey bristle worms I've seen in the tank. Any ideas? Looks more like a centipede with legs along it's body as oppoed to bristles down the entire length but it is quick so I can't be sure.

Any help IDing would be great. Sorry no pics for now.
