My 55 gal. reef tank has been running for about 5 years, when the lights go out at night tiny white snales come out in great numbers I mean like hundreds they seem to be everywhere ,on the live rock the glass. My fish are fine and they don't seem to harm my corals, I guess I'm just curious as to what they are and where do they come from? Will they pose a threat ? I have about 45 pounds of live rock thats been in the tank for several years and havn't added any new rock recently.
