Long, very skinny, red worm

[rayd8s]

Ok, this thingie is too small and too close to my LR to get a decent picture so I'll be as descriptive as I can.

 

It's rather long at a least 2 inches, is as thin as a piece of hair, is blood red with one end having very transperant bands of white. It either has several tentacles, or is reproducing as I can see as many as 4 'ends'. It sticks close to the rock and has no leg like appendages. It's taken up home next to a hitchhicking feather duster, which it doesn't seem to bother.

 

Any ideas?

spaghetti worm perhaps.
