Week 1 MicroAquarium Observation

I set up my MicroAquarium by putting pond water from three different levels of bowl 1, which came from Tommy Schumpert Pond, Seven Islands Wildlife Refuge in Knox County, Tennessee, into the Aquarium, by putting plant A (Amblystegium varium, which is moss that was colleced from a natural spring in Fountain City Park in Knox County, TN) and by putting plant B (Utricularia vulgaris, which is flowerng plant and came from the Greenhouse in the White Avenue Biology Annex, at UTK). Shortly after, I put the aquarium underneath the microscope and noticed almost immediately that a multicellular nemotode was moving around wildly and when I observed the aquarium this week, I noticed that it was moving a little slower and that it liked to settle in the moss. Also, I saw what I thought was a worm but it turned out to be an Annelid and it was moving very randomly and very fast. This week, I noticed that it liked to stay either towards the sides or in the middle of the moss and didn't like the light very much. There was also a ton of single celled bacteria randomly moving around and this week I noticed that there were a lot more bacteria than last week and they were still randomly moving. The only thing that seemed truly stationary was the moss and flowering plant. That proved true again in this week's observation. There was one major change in the aquarium this week and that was there were way more bacteria and ciliates in there than there had been previously. There were also about 2 water mites that resembled tiny little spiders and there were many Chilomonas (small organisms with tails) and little black dots called Colpidum. There was also Epistylis (which resemble buttercups almost) and the Chilomonas would eat little bits of moss. The only thing that seemed to contan chlorophyll were the plants. There were also many more single celled oraganisms than multicellular ones. I did not noticed any dead organisms in the bottom of the tank this week, but there were many more organisms in the tank than before and most organisms seem to prefer the middle to the top or bottom of the tank.
