I think it is a little bristleworm

looks like a Sipunculan AKA Peanut Worm. does it look like its picking at the rocks, and dart back into the rocks when you shine a light on it? or does it crawl around?

yep sounds like its a peanut. these are great to have in the tank, they are good detrivoes. you may see some little sticks that look like they were made from detritus, thats the worms waste.
