 White specs moving around on the glass?
  
It's probably hard to see, considering they are so small. At first I thought they were just bubbles, but then I looked close and they are actually moving around and such. Any ideas? they are white and kinda look fuzzy? Hard to tell though because they are so small. Also, could they be free floating in the water, I thought they were bubbles but I have no idea where they'd be coming from, which leads me to believe that these little guys are free floating in my tank as well.
Tank has been going for a month now.
Thanks in advance!
