Observation 1

This observation was made exactly one week and two days after the initial creation of the MicroAquarium. Firstly, there was an overall greater level of activity, movement, and presence of organisms.



Rotifers proved to be the organisms I saw the most, totalling five. They were also the quickest moving and were found in all areas of the aquarium. They were observed anchored and feeding to plant material in the open mid-section of the aquarium, along the bottom muck, and openly "swimming" throughout the water from destination to destination.



Several Daphnea corpses were seen left unattended and loosely attached or snagged. They looked like a bean capsule that was opened into two concave compartments with a clear, skeleton system springing beneath them. Three corpses were seen and two live individuals were observed.



Ostracots were seen (about 2 total). These creatures moved with motor-like motion. They were extremely fast and had whisker-like projections helping to move them along. They tended to burrow amongst the bottom muck.



There were various kinds of linear, tube-like filamentus creatures. Some appeared red, while others looked green. They seemed to form a network system where they would attach to one plant material than bridge the water enviornment to hook onto a different plant material. A short one was seen attached to a plant and its bottom cell was more swollen and contained more green substance (chlorophyll ?) than its top cells which were further from the plant material itself.



Lastly, an almost transparent wormlike organism was seen moving through the water. It was small and had a split tail (like a snake's tongue).



Overall, the majority of the plant life was seen on the bottom muck or in Plant A (the mossier of the two).
