Here we have the converted pictures from last week. The round animal with the small tail is a type of rotifer (I gave the specific type in the post) and the other snake like animal is a plenarium.

Pictures
Alright, so I'm having trouble posting the pictures.... hopefully I'll get this figured out soon and get them up.

First Observation
These are the observations for 10/23.
This was the first observation after the initial setup for the aquarium. Dr. MacFarland and I took a picture of the whole Micro-Aquarium, and then took pictures through a microscope of a few different organisms. I believe we were also going to put a beta-fish food pellet in, but we were unable to do so. I also hope to have the pictures up soon, tonight or tomorrow.
Upon first observation, not much had changed between this week and last. The only thing I did note was there seemed to be fewer of the paramecium running around in the water, however, there was still too many for me to count well.
I did follow a “Rotifer Vulgaris” for a while as it inched along. The rotifer then seemed to anchor itself along the edge of some moss and stretch out into the water and feed on the particulates that it found. I also happened to observe a different type of rotifer, the rotifer “Disylainermis or Euclanis Macura”. I am pretty sure it was the Disylainermis. It is much more of a round shape than the Vulgaris, and it seemed to float around the edge of some moss as well, although I did not really see it feed.
Next I saw a Flagella, a “Peranema”, flipping its flagella around moving from place to place. Oddly enough it moved towards the flagella instead of away from it. The Peranema encountered a paramecium and seemed to check it out with the flagella before moving on.
The most exciting observation today was a couple of Copepods!!!! It’s the first multi- cellular creature I’ve observed, a member of Arthropoda. It looks similarly to a horseshoe crab. It moved by twitching it’s antennae and legs. It was moving in and out of the moss and seemed quite active. Hopefully I’ll be able to take a picture of one, or at least pull one from the net and stick it here so you can see what it looks like.

Initial observation
This blog is for the Botany 111 course. We are observing a micro aquarium that we put together in lab; taking note of the micro-organisms in it; the changes that occour in the next few weeks in the animals, the water, and the moss that we included; and besides that I'll also be including some more detailed information about one of the organisms that I can find.
Let's Start with the initial assembly and observations on 10/16.
After receiving the micro-aquarium the bottom layer of water and sediment I took from container 5. The middle layer I took from container 6, and the last layer of water I took from the surface water of the plant "Bramiliad" in the greenhouse. Also, the moss that was chosen to go in the micro-aquarium was moss "c". After letting everything settle for a few minutes, I put the aquarium under the microscope to observe what was there. There were many many oblong paramecium, more than what I could count in an organized fashion, rapidly swimming everywhere in straight lines, spirals loops, etc. Next there was a ciliate, I'm not sure which specific one, that looked like a flat pancake with hairs/flagella radiating outward around the edge of it's body. Also, I observed four Rotifers, rotifer vulgaris, inching in and around especially close to the moss. The last thing I have to report is the algae and strings of cyanobacteria that appears in the aquarium. The algae appeared in small single cell units rectangular in look floating and moving around. These were all over the aquarium, as well as strings of what appeared to be some sort of cyanobacteria (photosynthetic bacteria).
