Week 4 of the Microaquarium

I noticed that most of the live action was thriving near the thing Dr. McFarland inserted. I found two long nematodes this week. They were near each other and near the inserted object (sorry I cannot remember what this is called). I saw a new organism this week. I noticed two flatworms near the bottom of the tank. This was surprising to me,  I had not seen them before. I took note that Plant B side was pretty much dead this week which is unusual but I'm guessing everything moved to Plant A since Dr. McFarland inserted that thing. Plant B look a little deader too. It took to have lost some of its green color, it was more of a brownish color this week. That's about it for this week.
