Help me identify this crazy thing in my tank

[uruinimgina]

Greetings!
A few months ago I noticed this bizarre creature in my tank. It's about 2 millimeters long, wormlike, pink and with a lot of little legs. I don't know if it was attached to an anemone that I obtained around the same time or what. It normally seems to crawl withing the rocks at the bottom of the tank, but I disturbed it today while cleaning and it ended up on my silly castle. Here are some pictures, of fairly poor quality as I can't take closeups with my camera and it's so small.

Does anyone have any idea as to what this is and whether it's any danger or anything? I'm at a loss.

It looks like a bristleworm to me. They're a good thing to have around. Just don't touch them with your bare hand.

bristleworms. some are fine, some are killers. If you have ever been fishing in the ocean, often times they are sold in bait shops as "sand worms". They dont bite, even though they have huge fang teeth. I fish wih them all the time and have had them in my hands and have never been bitten.

You don't have to worry about a bristle worm "biting," but their spines can stick to you and irritate the skin the the same way as fiberglass insulation.

On the money!!!
Also, there is a type of bristleworm (known as a fireworm) thats bristles can induce quite a burning sensation when they are lodged in your skin. It is always best to avoid contact with these guys if you can help it. Wearing aquarium gloves is the best way to insure this.

If I had a bristle worm and did not want it, I would add either an arrow crab or a six line wrasse. They eat bristle worms, but they may pull at your feather dusters too.

I had a coral banded shrimp for about 6 years that also ate worm - bristles and dusters - found out the hard way with a fancy duster one day...

This is what I was referring to; not 'biting'. Thanks Aloha.
