Freaky Worm/Tentacle Looking Thing

To start off no I did not get a picture it hid too quickly once I turned on my light.  With that said I saw a 1 to 2 inch tentacle looking thing in one of my rocks.  It was Brownish.  I first thought that it was part of my  birds nest coral until it starting moving and when I tried to get a better look it retracted/hid in the rocks.  I have not been able to get it to come back out to try and get a pic but I will keep looking.  But any suggestions as to what it could be (I know there are probably thousands of things) would be appreciated.  Like I said I will keep the camera by my tank and takea pic as soon as I see it again? 

Ok so the one I first originally posted on I have not been able to see again.  However in looking for it I did come across another one I think might be the same thing that I saw a few times last night and once tonight.  It looks as though it lives in a small hole in one of my ricks and then comes out at night.  Holes size is maybe 1/16th of an inch about the size of the tip of a ball point pen.  It extends out approximately up to 1 inch or so.  looks almost white with a brown tip.  Doesnt seem to be hurting anything just kind of rummages around looking for stuff to eat (I assume). 

Try this website it list a bunch of common hitchhikers good and bad with pictures.
