What in the world?

I was looking for my so called "isopod" last night & I happened to find something else. Coming from under a piece of lr stretched out what i could see, 3 tentacle looking things. Clear in color and it looked like sand was being sucked through them. Turned the lights on and it retracted them.
Could my new found friend be a problem?
Not much info on it, no way my camera would have gotten it due to it's color. Blended well with sand.

 

There are many interesting things that will come attached to live rock many of which are harmless. It is interesting to watch and see what they do.
Could this be the critter? http://www.reefkeeping.com/issues/2002-06/rs/ I have many of them in my tank. Enjoy
