not sure what the thing is

[barnaclegirl]

Last night i was looking in the tank after all the lights were out and i noticed an earth worm type creature slithering out of the live rock. I have never noticed it before. The best decripition that I can give is that it kinda looks like the tip of a brittlestars leg without the spines. It was stretched out to about 3 inchs long when i saw it. I flipped the living room light on to get a better look and it retracted back into a small hole in the rock. Sorry i was unable to get any pics of it. If this sounds familar to anyone please let me know, also was wondering if it's harmful.
Thanx

Thomas,
It really didn't look like a bristle worm, from what I could see of it.
The body was smooth and had a solid brown-gray color to it.
any other ideas? I'm really puzzled

i also have two of what you explained..... earth worm looking thing without legs and is very smooth looking....also when i shine the flashlight on them they kind of "roll" inside themselvs to move..... right???
if so i would like to know exactly what they are and if their bad in any way..... i have been noticing chunks and cuts out of my leather and im not sure whats doing that

peanut worms are benefical and sounds like what you have. I dont know what would be getting our leather but doubt that its the worm. IMO

Thanks for asking the question. I have around 10 of them in my tank, they kind of roll in on themselves. I always wondered what they were but assumed no one would know. Stupid me. The power of the message board is once again revealed.

That was ilt !!!! A peanut worm Thank you so much for giving enough info to research, I didn't know where to begin looking. I guess I'll let him stay for awhile.
Thanks again
