Week 4 Observations

This week, there were more organisms and objects in the MicroAquarium. Several more ostracod shell casings were present, and therefore, more seed shrimp were seen swimming through the water and on the plants. In comparison to last week when only one difflugia was noted, there were a multitude seen this week. Also, there was at least one aeolosoma that ventured from outside of the pond scum and was in the plants. However, the majority of them remained in the pond scum. There were many tiny worms this week swimming amongst the plants. There was an increase in the number of spirogyra present also. The biggest increase, though, came in the number of cyclops in the MicroAquarium. It was difficult to count them, however, due to their fast movement.
