Worm identification

[JimCricket]

Hello! Anyone know what this is and if it's helpful or harmful in my reef tank? Thanks for any help here!

It is a bristle worm, don't touch it with you fingers or you will get stung.
Good clean up crew but some people don't like them.

Welcome to the A-Team! What size tank do you have? If you feed heavily, you could wind up seeing a lot of those. I've got a melenaurus wrasse in my 125 that keep their numbers down. They are still there, but I never see them.
