For observations recorded on Nov. 16 2012:
- About half of the water content had evaporated once more.
-The Amblestegium sank into the bottom of the Aquarium tank.
-Amount and variety of organisms observed was much greater than the previous observation
Creatures observed
-About 2 Diffludgia (sp.), one feeding using a tube protruding from it (Jahn 1949)
-4 Halteria (sp.), freely floating around the Aquarium (Jahn 1949)
-An Actinosphaerium (sp.) off the tip of an Amblestegium leaf (Jahn 1949) Seen approx. 3 prior, but not noted. Another noted freely floating.
-Endless Diatoms everywhere in the Aquarium. Some now organized into filamentous structures, forming stacks of cells.
-Another Vorticella (sp.) noted freely floating in the water, oddly.
-About three more Paramecium, one not even floating in the water.

Preliminary Observations
-Approximately half of the water had evaporated out of the Aquarium. Despite this, some organisms seemed to be able to survive. The Utricularia, however, were most certainly dying in places that lacked water, as can be seen below. On the other hand, the Amblestegium seemed to be still alive even in regions lacking water.
-A different Microscope was used this time, the Leitz Laborlux 11. The camera used was the Sony HD Handycam HDR-XR500
-Very few organims could be observed this week in terms of quantity or variety. However, there were a large number of Diatoms (and possibly other algae, but they were indistinct) at the bottom
Organism observed:
These and other Paramecium (Rainis and Russell 1996) I found floating freely in the Aquarium. I noted a fair number, possibly three to five, whereas previously, I had not seen any.
This photo I took of the Gibba (McFarland 2012) shows clear evidence of its decay.
By contrast, the Amblestegium (McFarland 2012) here seems almost more alive, making me wonder if it thrives even in lack of water.

Preliminary Notes
-Approximately the top fifth of the water had evaporated this time, and it was again replaced.
-Beta Fish food pellet added to the Aquarium on Oct. 26th, 2012. It was manufactured by "Atison's Beta Food", made by the Ocean Nutrition company, Aqua Pet Americas (located at 3528 West 500 South, Salt Lake City, UT 84104). The ingredients are as follows: Fish meal, wheat flower, soy meal, krill meal, minerals, vitamins and preservatives, resulting in a nutrional value of Crude Protein 36%; Crude fat 4.5%; Crude Fiber 3.5%; Moisture 8% and Ash 15% (McFarland 2012)
-The microscope model used was the Olympus CH30 microscope. The camcorder model was also recorded, but improperly, and will have to be rerecorded next time.
-I observed a larger quantity of organisms this time, but the variety remained roughly the same. This time, however, I noticed many more organisms floating freely around the Aqaurium, whereas previously, they were mostly concentrated within the dirt layer, though my examples below may show otherwise. Many of the free-floating organisms are indistinguishable from water droplets (and thus difficult to get a good photograph of), or organisms I had observed the prior week, so I had little choice but to ignore them.
-The dirt layer within the Aquarium had been almost entirely broken up. The dirt particles I observed were much smaller and more evenly dispersed as opposed to last time, and hardly concealed any organisms at all.
-Some of the leaves of the Gibba and the Amblestegium sp. were browning, indicating that many of them may have died or been eaten.
Organisms observed:
I found this Closterium algae near the bottom of the Aquarium as well, strangely. It did move, but very slowly, so I attribute this to the currents within the Aquarium (Prescott 1954).

Organisms observed:
This Ameoba I found near the bottom of the Aquarium, not moving much on its own, although the insides were undulating rapidly (Rainis and Russell 1996).
These Diatoma algae were also found near the bottom, and resemble green rectangles (Prescott 1954).I suspect they were growing there due to the nutrients to be found in what little soil there was left.
