Hair thin clear worms

[Dingo Dog]

I have these thin whispy worm things that are about 1" long. Mostly they're in the sand. Some built tiny sand tubes to hide in. It seems each one has two tenticals. More and more I've noticed them coming out of the rocks so it seems they're flourishing.
What are they?
Are they good/bad?
What can I do to get rid of them or decrease their number?

Thanks.

I have them as well......nothing to worry about, signs of a healthy tank!

I think they are called spaghetti worms. They are good for your tank and as said, are a sign of a healthy tank and sand bed. They eat waste and uneaten food. No need to get rid of them, ppl pay money for worms like that. I actually feed my tank light so occasionally hand feed them by dropping tiny bits of food by them before lights out. Very cool little worms to watch.

Enjoy and grats :smokin:

sounds like Chaetopterid or Spionid worms. you should be able to google up some images of them. they are harmless filter feeders.

Paintbug, you nailed it. I did a Google search and found this article: http://reefkeeping.com/issues/2003-05/rs/index.php
The worms in my tank are the Spionidae/Chaetopteridae.
Thanks to all my fellow reefers for your replies! I feel much better now knowing more about these worms.
Happy reefing to all!
