Week Four MicroAquarium Observation

During this week’s observation of my microaquarium, I saw similar organisms at last week, such as the many hundreds of small bodos moving all about the aquarium.  Many worm- like organisms were seen as well, one was able to be identified as Aeolosoma Ehrenberg, as pictured in figure 2 (Ward 1918).  This worm had reddish orange spots running along it, with small hair-like filaments along the side.   This week I was also able to snap a picture of one of the Cyclopes living in the aquarium (figure 1) (Thorp 2010).  Of the same two I observed last week, one appeared larger (figure 1) with larger matching sacs on either sides of its body towards the rear of the organism.  The plants appeared healthy and green, they have a larger amount cyanobacteria growing this week. There also seemed to be more life within the soil at the bottom of the aquarium.
