Small smooth blue worm hitchhiker?

[Polypnewbie]

I've had an eagle eye colony for 2 1/2 months. All sorts of things came with it unbeknownst to me, aiptasia, asterina, vermetids, and red tube worms. I actually put the asterinas and aiptasia in their own fishbowl. I left the vermetid snails and red tube worms where they were (cause really I couldn't get to them anyway). There hasn't been a resurfacing of any aiptasia or asterinas since that first week. I have tried to be careful.

So, how could a small smooth blue worm have been hidden for 2.5 months until today? I only saw it briefly and not up close enough to see if it is truly smooth at a much more microscopic level, but I don't see or hear about worms like this in my online searches. It's about an inch or less, and semi light blue. It swam around for a minute then settled into the substrate, half buried. Could it be that this thing is a hitchhiker and went right into the sand so I never saw it until today?

And most importantly, please tell me what it is.

I have a useless picture I will attempt, and most likely fail, to post

It's now half embedded in the sand (amongst the horrendous algae problem I know I have). It looks like it's curled up in a ball, but it isn't. It's just the angle of the photo.

Yeah can't tell by the pic

I'm probably wrong, and I don't know the actual name (though I doubt I could spell it if I knew it), but if your QT has been spot on, could the 'worm' actually be a bristle worm reproductive thingy?

Scoop it out and put it in a bowl and take a clear pic for ID. There's no possible way anyone can ID it with the info provided.

Plus start a photobucket account, upload the image, then copy the direct link to the image, and paste it into the body of your post like this.

Like mentioned above, if you saw it swimming around for awhile then my guess would be some sort of Polychaete epitoke as well. (baby worms)
