saltwater centipede?

[derict]

am new to salt tanks and all, is actually son's tank and I have had the joy of it now that he has moved home. this evening when we were feeding some anemonies we have, common ones I am sure, we noticed what looked like, as best as I can discrive, a flat centepede. info on tank, is 29gal salt, with live rock from fiji. did not get a pic, appeared to be approx 3/4 to 1 inch long and maybe 1/4 inch wide, had legs full length of body, ends appeared to be almost translucent with the mid section brownish. it came out while feeding frozen brine shrimp and almost immediatly returned, is the first time I have seen it and spend several minutes several times a day looking for new and differnt things. any help to identify, or a location to search for the answers would be great. thanks

It sounds like a harmless and very common bristleworm.
