Micro Aquarium 10/31

I went to observe my aquarium around noon on 10/31. The water in my aquarium has become less clear. From a distance I saw a small white ring in the top corner, but when I zoomed in I saw many moving organisms. Most of the organisms were Aeolosoma worms (Pennak, 1989). This is pictured below in Figure 1. As I moved a little outside the circle I observed some single cell organisms called Vorticella (Patterson, 1996). This is pictured below in Figure 2. I also observed many rotifer. The rotifers I saw are called Lecane (Pennak, 1989). As far as my previous blog, the Limneas sp. were no longer living. I saw the skeletons of the tubes they were in which was interesting.
