Recently i have noticed these worm like creatures ranging from 1/4 to 1/2 inch in lentgh swimming in my tank. They wiggle violently. I am new to this site as well and will use this as a introduction. I have a 125 gal reef tank one rabbit, one bullet goby, one algea bleny, three chromis and a clown. I also have a few mushrooms, a gonoporia and various polyps. Multipul cleaners from turbos, crabs, hermitts etc.

Any info on weather these creatures are dangerous or not would be helpful. I see no damage to any livestock but I have not seen any thing like them before. No new L.R. introduced and all is well other than the white wigglers. All attemps to photograph have failed since they only come out in total darkness and I cannot get a clear photo.
