3rd observation

I observed my micro aquarium on October 27,2009. A few things have changed since last week when I checked it. There were quite a few new organisms that I either didn't notice last time or didn't exist. Rotifers and ciliates where the new organisms I noticed in my microaquarium. Rotifers have hairy appendages, are transparent, wheel-like, and move very fast in random motion. Ciliates are a reddish color and are free moving. They are an oval type shape. I also noticed quite a bit of single celled organisms free moving around, and at the very bottom was some green colored algea.
