Nighttime weird critter

[newfound77951]

I happened to go downstairs last night at about 3AM....thought I'd take a peek in the tank and see what was crawling around under the moonlights, thought maybe I'd see my serpent star. What I did see were two very long, very retractile "worms" that would come shooting out of the live rock, poke around and then retract back in. one was about 1-1.5" long max, but the other one could reach 4+" and was 1/8" thick or more. They were on separate rocks, and didn't seem to have heads....any ideas what they might be?

I couldn't get a pic, unfortunately, I think the flash would have sent them into hiding pretty fast!

Did they look anything like These http://www.xtalworld.com/Aquarium/hitchfaq.htm?

not sure which ones you meant...but they don't look like any of the listed polychaetes or sipunculans. It kind of looks like the pic of the spionid worm but I only saw one tentacle and they were pretty big.

Sounds to me like a peanut worm. Was it kind of brownish grey in color?

It was under the lunar lights.....everything looked blue! But I could tell it was uniformly colored, somewhat transparent, and might have been brownish gray.
