Entry 3

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:


 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).

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).

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.
