I wish I could get a picture to show you, but this thing is strictly nocturnal and I can't get a good shot of it. It is also small and I do not have a good macro lens yet. I bet the experts here can tell me though.

It lives in the rock. There's a small 1/16" round hole it comes out of at night. It looks like a non-segmented worm, but it is so small I cannot tell if it has segments or not. It is white/biege and translucent. It comes out about an inch, picks up a single piece of sand and swallows it. You can actually watch the piece of sand go through it until it disappears into the rock. It picks up one piece after another and does the same thing. In the morning, it looks like it has thrown up. There is a cylindrical rod that is apparently just the sand stuck together that it ate. So it eats sand, cleans it of life, then spits it back out into a pile of rods outside its burrow.

I have not found a picture of it on the web yet, so any help would be greatly appreciated.
 
It does not look like that. There is simply a hole in the rock that it comes out of. Not a tube or anything that protrudes from the rock.
 
I have the same thing in my tank (comes out of the live rock from fiji). Strictly nocturnal and very difficult to photograph. As soon as the flashlight hits it it w/draws back into the rock. I will "try" to get a pic and post.

Please post an answer if you have discovered what it is! JWG
