I am in the process of setting up a reef tank and have been cycling my live rock. Saw this guy in there today and I am trying to determine what he is and if he is something that will be safe to keep in the tank.
Locality: Oneida, Tank floor, NY, Reef tank, 12 January 2007, Hitchhiked on live rock. Length: 1-1.5 inches. Photographer: Matthew Rush.

Since it looks quite slug-like I can give you a quick answer. It is a Sipunculid or peanut Worm. Shouldn't be a problem in your aquarium but may get eaten.
