Worm ID help

[dogmajones]

I have noticed a worm in my liverock the last few nights, it is built like a centipede has the individual legs, and appears to have a segmented body, it is tan color with a very thin pointed black head no visible tentacles, it's head looks like a bristleworm head but it doesn't have bristles rather it has the individual legs running up it's body

worm 2
it is light brown color , very thin worm that stretches a a huge distance, it also has what appears to be a segmented body with legs centipede style, but it's head is rounded and white with 2 visible eyes

I couldn't catch a pic as they were too fast, and I haven't been able to ID them via the internet so hoping an experienced hobbyist can help me ID these 2 types of worms

Unfortunately I cannot think of a worm that matches those descriptions at the moment, here are my favorite ID sites though
LionfishLair.com - Hitchhiker Guide to your Aquarium
Live Rock Hitch Hikers
Hitchhikers Guide to the Reef Tank - RTAW Reefpedia

ya I have checked these sites among many others and haven't been able to ID these worms just yet, thank you for the reply

Sorry about that! Good luck with the ID!

It's not a worm, sounds like a bristle starfish, they will hide under a rock/crevasse and all you will see is a prickly worm like thing swaying in the water trapping debris?

Very beneficial for your tank!
