ID Please

Found this worm crawling on my overflow box so I sucked it up with the turkey baster just in case it was bad. Can someone ID this?

I'm not sure if it is a peanut worm, mostly because peanuts usually have small tentacles all around the the mouth. Eunicids usually have 5 at the front of the head, but the one in the photo has tentacles that appear to be at the side. You may need Leslie to ID it.

it's a dorvilleid polychaete. They're micro-hunters & grazers. It won't damage anything you care about.
