This is bugging me. At night I have a ZILLION tiny little white dots all over my glass. They look like very small snails. I will try to snap a picture, but I'm pretty sure it will simply turn out to look like tiny little white dots! Any idea what these might be? Are they good guys? If not what will eat them? I have a feeling these little fellas are what ate my Yellow Star Polyp colony. Never saw them doing it, but now that the colony is gone, I see more of these white dots on the glass, power heads, overflow.....everywhere.
