On 11/6 my acquarium was not as active as it had been the past few times I observed it. I was only able to find one midge alive. One was dead and I could not find the other at all. Other than that I really didn't see anything new and I saw nothing exciting. Also I was not able to find any of the Litonus, Urocentrum, or the Euplotes.

On 10/29 in my observations I was able to see that the three midges that I had seen before had grown and were considerably bigger that when I last observed them. Although there were no measurements I could now see them with the naked eye as I could not before.The Urocentrum that I had observed before were not easily found and I believe there are now less of them. New species that I found were Uplotes which is a common Hypotrich ciliate and there were many.
Litonotus which can be recognized by its long neck (only saw one) and Tachysoma. The Halteria and Rotofors were still present but I was not able to find the Paramesiums that I had seen the week before.

For my microacquarium project I used water source 12 and used plant sources A and B. On October 15, in class I was able to see what appeared to be a paramesium and 1 midge. Observations on this day were brief but after further observation on october 21, two midges were visible. Also using the book "Freeliving Freshwater Protozoa: A Color Guide," urocentrum were able to be identified. These are easily identifeied because the move like a spinning top. I was able to see 10 in one view of the microscope and I believe there to be more present in the acquarium. With the help of our lab instructor I was able to see copepods, rodofors, and cilia.
