Looking for ID on mystery worm (pic)

[silverado_4x4]

Found this little bugger in my tank today. curious as to an ID on him. When he was in one piece (broke him when i was pulling him outta the rock) he was probably 6-8 inches easy, with the ability to stretch out longer. Any info would be great.

Could be a eunicd. I say that because of the antenna on it's head.

Agreed, a Eunicid and usually not something you want in an enclosed system as they have been known to become quite destructive as they get larger. For more photos please see the worm section of my hitch hiker pages.
