Week 2 of the MicroAquarium

Today I saw an Annelid in my aquarium. I did not see it last week. An annelid is a legless and segmented organism. It moved slower than the nematode, but could move fast at times. It was also filled with red dots. I again saw some smaller single-celled organisms that were transparent. I saw some multi-cellular organisms, too. I noticed one green colored organism. I was not sure what kind it was. I also gathered from watching my aquarium today that the organisms seemed to be more around Plant B than Plant A. I also noticed a rotifer in the water.
