What kind of worm is this?

[jfabritz]

While on the hunt for some cirolanid isopods (sigh) I happened upon this worm flashing its way along the currents. I trapped him in my brine shrimp net and took a picture.

He looks like a isopod that has a really really long body. The color changes to almost a blood red to the end. He was crawling on the net and would occasionally thrust out what looked like two spike mandibles that would give me the heebie jeebies.

Any thoughts on what this is and should I raise the threat level to orange?

Thanks!

It looks a lot like a Peanut Worm to me, They're like bristle worms, they do good work in your tank but some people don't like worms at all!

But don't take my ID as proof, lets wait and see what others say.

It does look like a peanut worm to me, they are harmless detritavores that only come out at night

This worm looks nothing like the one I saw on Melev's Reef (http://www.melevsreef.com/node/361).

If I said it looked like something, see this site (http://chucksaddiction.thefishestate.net/hitchworms.html) and look at the fifth row of the nemertea. It looked a little like that.

Here is another photo I took, unfortunately it focused on the net instead of the worm.
