Final Observation

Today I observed my MicroAquarium for the last time.  The organisms in the aquarium have increased again, most of them are still towards the top of the tank feeding.  The plants show definite signs of being eaten, and there is plant and dirt debris all over the place throughout the aquarium.  Towards the bottom of the aquarium several more of the same fungi have appeared and many dead organisms can be seen barely sticking out of the dirt. It looks like new plants of the same type already in the aquarium have started to grow out of the dirt on the bottom.  An Ostracoda (seed shrimp) which i had found earlier in the week has grown about twice the size it was when i first saw it.  Ostracoda move around by means of beating movements of the first and second antennae, and feed mostly on bacteria, molds, and algae (Smith 2001).  While watching this little guy, he was moving rapidly all around the aquarium, and feeding often.  I couldn't locate any new organisms but the ones that I've been seeing have increased in great number.
