My tank has been cycling for about the last month and a half, and I have started to notice these things on the walls of my tank. I see about 1 or 2 of them a night after the lights go out. The picture is pretty bad, so I will try to describe it... There isnt much to it, other than a white oval body with 2 legs. It moves around the glass, sucking on it like a snail would, but it has no shell. They are about 1-2 mm in length. Anyone know what they are and if they are reef safe? Thanks!!
