Help ID UWLC (unidentified worm like creature)

[bagged87blayzer]

Alright first off sorry for the horrible pic. This is what the pic is of. I have about 3 or 4 of these in one piece of rock (that I can see at least). Some are black and white and the others are white and red. Honestly they look like little legs to a serpent star. I do not see more the 2 or 3 legs ad that is it at a time. Anyone have any idea??

the pic makes them look bigger then they actually are they are no bigger then maybe a 1/4 inch long. They really only come out when i feed

The top one looks like the arm of a brittle starfish. The bottom looks like tube worms.

I have dozens of the brittlestars in the pic all over my tank. All you ever see is a limb or two sticking out of a hole in the rock. The tube worms are often a kind of small feather duster worm.
