In this assignment, you will observe the progress of a 5 gallon aquarium  that utilizes no filtering or CO2. Instead it tries to reproduce what  would happen in a natural pond. You DO NOT have to do a tank yourself  (but if you like fish and feel inspired this is a great video series to  watch). You will watch the progress videos form the assigned video  series, and contribute to the assignment journal, considering the  questions posed for each video. 

 Watch the videos corresponding to 6 and 7th months. What is happening to  the population? How does this relate to what you observed in the plant  population during earlier months? What effect do you think the increase  in population may have on the aquarium if it is not managed?
