Note: water was added equal to the amount as before.

When viewing the aquarium this week I notced a significant change from last week. Last time there was almost no movement in plant A. This week was exactly opposite. There were lots of organisms feeding in plant A and in plant B life was scarce.
The organisms observed this week included a worm-like organism with two thick flagella attached to its rear. These were numerous around plant A. Upon his viewing of the organism Dr. McFarland stated that this was probably a species of rotifer.
Also seen were oval creatures who were frantically swimming around
plant A as well. There were also multple organisms like this one.
The third and final creature viewed was also speculated to be a rotifer species. However, unlike

the other rotifer species seen this being was attached to a stem of plant A while feeding. It had many tiny hair thin cillia spining in a circular motion. It was unclear whether this was adifferent species than before or if it was simply feeding and therefore was observed as different than the first rotifer.
