Help ID unknown worm

[CRath]

Hello, I need help on an Id of this critter. at first it looked like a nudibranch when I saw it posted up on top of my rockwork. after fishing it out of the tank I can now tell that it has a bunch of long streamers coming off of it. Sorry about the doo doo iPhone pictures.

Might be a hair worm.

Google is your friend ;)

I can't tell for sure if it's a hair worm, but no, they are not bad. They are a great part of your cuc.

That was my thoughts. A type of spaghetti worm. I've had red ones in my tank--they are great for clean up. Once it finds a spot in your sand or rocks, it will let out it's hair tentacles to clean up scraps. Never even seen them touching my corals.

Spaghetti worms are a different animal, despite the recent trend of mis-naming hair worms.

Thanks! I'll spend some time on Google to learn how to ID the two.

Unfortunately, most google results will give you incorrect info.

Here's an article that explains the difference... scroll down to the second section called "Spaghetti, Vermicelli, and Hair Worms".
