Observation of the MicroAquarium 4

This is the fourth week and fourth observation of my microaquarium. It is my last observation of the microaquarium. The food pellets were completely gone and a lot of water has evaporated. I saw many of the same organisms as in the previous observations, such as a mite near the bottom of the microaquarium, but there was a lot less movement. There was cyanobacteria everywhere, such as Oscillatoria. Most organisms that were left were near the plants. The plants were more brownish this week and there was less soil. Overall the microaquarium looked pretty dead.

Observation of the MicroAquarium 3

I went and observed my microaquarium on Thursday November 3rd at about 1:00. I saw some different organisms since last weeks observation. For example, I saw several gastrotrich, which is a brown, transparent organism with three lobes and two pairs of tufts with two curved prongs on the end and swims fast. These were found towards the surface of the microaquarium. There were also many paramecium and rotifers toward the surface or around the plants. I also noticed there were not very many organisms near the soil this week. I also saw another cyclops this week. The pellets have gotten much smaller from last week and the two plants in the microaquarium have started turning brown. Through my observation this week, I have come to the conclusion that the organisms are starting to die.
