looks like a bristle worm
Bristleworms range in size from small (about 1" long) up to very large at about 20" in length. Most small ones are an orange color, sometime appearing two-tone in color. Larger bristleworms are frequently gray or brownish in color. Bristleworms are composed of many segments and have bristles (setae) which extend from both sides of its body along its entire length, hence their common name. These setae are clearly visible in the picture above. Bristle worms live in the sand or within the live rock. They are nocturnal and not usually seen during the day.

Bristle worms are good for the aquarium as long as you don't touch them, they are excellent at cleaning up. They eat leftover food and detritus.
