I recently found these in my fish tanks. I've only seen one in the 150gallon, and I've seen 2 in the 10 gallon nano. Of course it is easier to look at everthing in the nano. These are as clear as I could get since they are 1-2mm in size and like to move around. It is interesting to watch them pulse around the tank though. If anyone can Identify them I would be really appreciative.
