This past week when I went to observe my micro aquarium, I found many new organisms and multiple of previously existed. Last week I discovered annelid that could be found in the muck at the bottom of the aquarium. This week, I found possibly 2 if not 3 stylaria annelids found in the same location. When observing the annelids, they were all eating which was understood by the contraction of their stomachs. I have yet to observe these organisms in a location other than in muck. Another organism that was found last week that multiplied was the vorticella, however, the location was different this week from the last. Last week the vorticella could be found anchored to the stems of plant B, and there were only a few that I spotted. This observation, the vorticellas were mostly found around the food pellet. This difference between the last observation and this past one was the vorticella were not anchored down, they were erratically placed freely around the food pellet. The number of vorticella tripled if not quadrupled. There were still many rotifer and Cyclops like last week. The rotifer and Cyclops move so random and freely, that it is hard to tell if they are reproducing, or if I am observing the same rotifer 3 or 4 times.
I noticed that this week my plant stems were turning a little more brown, which leads me to believe that they are dying. Plant A is in much worse shape than plant B. Almost all of my plant A is brown, and there is less activity that happens around plant A than the other. Plant B had a few brown spots in it, but most of the stems were very much green and alive. A lot of the stems were cluttered with diatoms. Dr. McFarland identified rizoids, a moss, which was anchored to plant B. The rhizoids looked like flowers growing out of the stem. There were several desmids, single cell algae also surrounding plant B.
Despite the growth in previously existing organisms, there were also many new organisms that were discovered in my observation. I discovered new organisms that Dr. McFarland identified as flat worms, which was a transparent looking organism, moving freely through my aquarium. These worms could be found anywhere in the aquarium. Another new found organisms was the dixa midge (Ward, and Whipple). These organisms are long, skinny, and moved freely, but they actually have what looks like a face. On the head, there are 2 black dots that are the eyes, and red at the mouth area, they almost resembled a sock monkey.
Before leaving the lab, I placed 1 Atison's Betta Food pellet in the aquarium, but this time instead of placing it near plant B, I have placed it around plant A to see if next week there will be more activity around plant A versus plant B. After placing the food pellet in the aquarium, I filled the rest of the aquarium up with water.
