Observation Week 2

My first observation of my aquarium under the microscope was interesting. I realized that my water level had dropped from when I first observed it in lab. I also realized that the plants had either grown or spread throughout the aquarium. I observed many organisms living in the aquarium and they seemed to be feeding off the soil and squirming around quickly in the water. There were several rotifers swimming around in the soil.

Observation Week 5

In observing my aquarium this week I once again noticed that my water level had decreased dramatically. My plants had seemed to be dying and I believe its possible that they may have already been dead. Under the microscope I spotted Euchlanis sp. Cyclopoid sp. Litonotus sp. and Cyclidium sp. I also observed a saw a few other new organisms however I did not identify them.

The following are pictures I identified from my microaquarium:

Observation Week 4

In observing my aquarium this week I found many paramecium and rotifers around the plants and close to the surface. My plants have began to look ill and are turning brown as if they are dying. The pellets didnt seem to have much change to them however they did seem to have decreased in size a bit. Im not sure if the organisms are beginning to die however that seems to be the observation Im seeing. My water level had evaporated once again this week.
