Answer
Steve,

Do you have any fish in the tank? If you do then I would say you have a planaria out break. These little worms come around when the fish are being over fed. You can get rid of them by raising the temp in the tank and doing a lot of water changes. These little guys will not harm the fish. You can stop feeding them for a few days and they will eat the little worms. They will not harm your fish at all. I would cut down on the feeding of the live rocks if you do not have fish. Let me know if you have any more questions
