I identified several new organisms that I had not seen at all until this week, including a mite. QUITE exciting! Below is a video. I was fascinated by the hooked "arms" it used to catch food.
I also found a highly increased number of Raphidocustis in and around where the algae met the sediment in the bottom. The flagella are easily its most defining characteristic, as it has any small and a couple long ones all around its perimeter.

The other new organism I observed was Peranema, which was somewhat easy to identify because of its motility and long flagella. I looked for some time, but I only saw one. May guess is conditions are becoming more favorable toward them and their numbers would increase were more observations to be taken.

The rest of the organisms I photographed are ones that I had seen before, but this week the amoeba seemed to have increased in number, concentrated in the bottom half of the micro-aquarium, and the Colpidium were more "active" and in larger number. The euplote pictured below is one of only a very few I observed over the course of the past month, and upon seeing it in the book I found it incredible how it can actually use its flagella as "legs" to traverse substrate (which explained how it seemed to scuttle in and out of it differently than any of the other organisms).
