ID this worm thing?

So first of no picture, I know hard to id with out it I am sorry but here is hoping I explain it well enough.
Last night after I turned out the lights in my tank I noticed these little worm looking things expanding out of holes in the rocks. They moved a little like a earthworm and at the end of the tube it looked like a hole or mouth that was trying to eat copepods. They were mostly clear and a little white. And as soon as I turned on the light they retreated into the rocks again.
I never saw the end of them all I saw was a tube coming out of the rocks extending all over the rocks.

Thank you any information leading to the arrest of this unknown creature is greatly appreciated.

 

could be bristle worms, but they're pink. Only come out at night

 

Not a bristle worm that is for sure. They kind of look like an aliens finger, if that makes any sense.

 

what about texture? smooth and round? Bubbly? hairy? well...maybe not hairy...but you get the idea.

 

Sounds like a peanut worm.. they're tan, whitish, black marble colored. The retract when lights hit them. if that's what they are they're good hitchhikers! The have a scraper for a mouth, it looks kind of jagged, and they scpe rocks with it.

 

Its texture is smooth and slimy looking if I were to hold it im sure.

Its not a peanut worm, not that thick much skinner.

 

Does it have any lighter colored rings on it?

 

Maybe one, a thin white one. But its body was mainly see through with a bit of tan.

 

Bump still wondering.

 

I've kindve got the same things. mine are skinny, the color of an earthwarm and i have a bunch of them. dont notice a mouth but yeah.
