Week 2

This week I can see some changes that have happened. There are many more living organisms then there was last week. I saw Anisonema sp. swimming around in the open waters of my aquarium. These organisms were very small single cell organisms that move at a quick rate. There are many of them swimming around all over the place. This organism has antanna's on it and it also has a vacuole. The organism is a dull color almost clear looking. Next, I saw Colpidum sp. that would swim around in the open water as well. It was fairly slow moving and there was no where near as much of these. These were rounded and had cilia growing all around it. Both of these organisms lived in all parts of my aquarium. Lastly, I saw a very large organism at the bottom of my aquarium living through the dirt. It seemed to be a bottom feeder. It looked like a worm and would move around in a s shape movement. There were also a number of large dead organisms laying in the bottom of the aquarium decomposing. I was very interested to see the many different organisms in my aquarium this week.
