Pale worms

I've just recently noticed a new guest in my tanks and hoped someone
could shed some light on what they are.

They are long pale flesh colored worm like tentacles, two per hole,
incased in a long tube made up of the sand. I've seen them build the
tube. The tentacle comes out, I've seen one at least two inches long,
and grabs a piece of sand and takes it back and attaches it to the
tube. Really pretty cool.

I've been unable to come up with what they are on the web. Anyone
know what they are and if they are harmful?

Hi Ctmidnite,

I've got those as well, in my display and in my refugium. They are beneficial
to your clean up crew, always consuming detritus and bits of floating food in
the water column. I don't believe I've seen them named before, but you can
enjoy the show.
