Week 4

Thursday, November 12, 2007
When I first looked at the microaqarium, I noticed a lot of dead matter that has collected at the bottom of the aqarium. The algae has continued to grow; however, now it has spread to the entire aquarium instead of just in the corner it had been place in originally. Once I began to look at my aquarium under the microscope, I could see different kinds of algea growing all over the sides of the aquarium. The algae increase in numbers; however, most of the organism decreased. The only dead organisms I could distinctly see in the material at the bottom of the aquarium was several freshwater shrimp. The only living organisms I saw in my aquarium was rotifers and annelids. The vorticella also remained about the same in numbers. In fact, I also witnessed the vorticella budding. I did not see any new organism this week.

Week 3

When I looked at my microaquarium with my naked-eye, I notice that the plants had really began to grow. Plant B had new limbs growing off of it, and the algae had grown substantially. I also notice that a lot of the dirt in the bottom of the aquarium was gone. Most of the nematodes had died; however, the few left were much larger.

Most of the organisms in my aquarium had decreases dramatically in numbers except the rotifers. I was able to spot several dead nemotodes and a few dead freshwater shrimp. There were several new types of algae in my aquarium. I found fragilaria a yellow square-like organism that was surrounded by rotifers no matter where I found it in my aqarium. I also found some gomphonema (top left picture) an attached algae that are made up of yellow cone-like shape. I also spotted a few new organisms. I spotted a amoeba which was a purple color from the food it was eating. There was one organism that seemed to really thrive since my last observation and that was the vorticlla (top right picture). They attach themselves to an item whether that be a plant or the wall of the aquarium and use moving bristles to form a vortex that pulls food to them.
