What is this creature in my salt water tank?

Question

I have a bio cube 29g salt water tank which has been going for about 9 months now. I noticed one day a black n' white creature poking out of a hole in one of my rocks.

It was black and white sequenced about 2 inches long from what i saw. it was slithery and did not have a shell.

i poked it didn't move and i poked it again and it moved slowly down back into its hole.

obviously it is a hitch-hicker that came with my rock when I bought it but i have no idea what it is exactly.

ANY IDEAS???

I am almost 100% sure it would be a peanut worm. Similar to the bristle worm(the long pink ones), they are good to have around.
