Week 5

This week about 1,000 new rotifers had appeared. They were swimming haphazardly in every direction. A noticed a new variety of flatworm. This one was a more brown color than clear, and its body was segmented. I saw dead bodies of two copepods. They were sitting on the algae lifelessly. I found an organism that had a bright red center in it. The dirt from the bottom of the aquarium has been scattered all around. The most interesting thing this week was a large mass of colpts that seemed to be absorbing nutrients from a dead flatworm. There were hundreds of them swimming in a clump around the body, moving it back and forth. The algae had formed circular heads.
