Day 5

I last observed my MicroAquarium on November 11, 2010.  Upon observing my aquarium I noticed a few changes.  There were still many bacteria, a lot of diatoms, and still many cynobacteria.  One of the many diatoms identified is known as  Navicula sp. (Tiffany and Britton, Fig. 782).  I noticed that there were less Ostracoda sp.  There were also more Euchlanis sp. that I identified in my last observation.  I observed more rotifers identified as Eplaxis sp. identified in my last observation as well.  I observed a new organism that was identified as Actinophrys sp. there were many of these tiny organisms (Patterson, Fig. 396).  There were still many cyclopes in my MicroAquarium.  These seem to be surviving well considering I also noticed several juvenile cyclopes.  There were a few of another type of rotifer that I identified as Lecane sp. (Smith, Fig. 7.36).  I also observed a few flat worms that I have not seen since the first few observations.  Overall there are less large organisms and many small bacteria and tiny organisms.
