This week, as a observed the aquarium, I noticed that the soil and water levels had continued to decrease. I added more added more distilled water to compensate. Also this week, I decided to count some of the organisms that I have already identified. I could have very well missed a few, but I counted 5 nauplii, 6 annelids, 8 nematodes, and 3 cyclopes. I was somewhat surprised by the numerical count of the various organisms in the aquarium. But, it is considered it to be an empire, so I shouldn't be too surprised by its population. There are also an extensive amount of various paramecium. I also identified a species of rotifer. I have been seeing this organism making its way around town frequently in the past, and I finally resolved to identify it. It is a Lepadella ovalis (Donner 18). It is a oval shaped organism with a whip-like, pointed tail structure with two eyes.
