What kind of worm is this?

Just noticed this guy a few minutes ago for the first time. I'm thinking large bristle worm. I'm certain there was a smaller one on the glass earlier as well. Here's a couple pics before it slid back into it's cavern;

Looks like a common bristle worm. Good clean up crew member

Kinda figured. Never seen such a large one in person before. This thing has to be over 3" long.

they have the potential to get pretty big. If you notice their numbers getting to big, cut back on feeding and access nutrients in the tank
