Plant life and animal life this week have again made a significant increase! The algae population has grown to about twice of its volume from what it was last week. There are some brown string like growth structures that have appeared on sections of the moss this week. I believe they might be the beginnings of root structures, as they are growing towards the bottom of the aquarium. The also are only appearing on the ends of certain parts of the moss, this also leading me to the conclusion that they are roots.
The Animal life has again increased significiantly, especially in the higher life forms. The multi-cellular forms have shown the biggest increase. There are a lot more Plenariums, Copepods, and Cyclops. In fact Dr. McFarland observed some creatures that I had seen, and there were many of them around the aquarium, and we identified them as baby Cyclops!
During the observation, I was able to see where a Cyclops had died and left it’s skeleton. At the remains were approximately a dozen paramecium circling, and bumping, and perhaps crawling along the body. It seemed as if they were feeding, or trying to feed off of it.

Observation3
On Thursday 10/25/07 Dr. McFarland added a Beta Fish food pellet to the aquarium. The details are as follows: It is made by Ocean Nutrition, Aqua Pet Americas, 3528 West 500 South, Salt Lake City, UT 84104. Ingredients: Fish meal, wheat flower, soy meal, krill meal, minerals, vitamins and preservatives. Analysis: Crude Protein 36%; Crude fat 4.5%; Crude Fiber 3.5%; Moisture 8% and Ash 15%.
It has made a drastic difference in the Micro Aquarium! Even by looking with the unaided eye you can tell there is an increased amount of vegetation growth. The greatest increase appears to have been with the algae. There are strings of algae anchored all over the aquarium. There is also a marked increase in animal life as well. Last week I had trouble locating some organisms, however this week everywhere I have observed there have been large amounts of varied types of organisms. I was able to observe a water flea for the first time this week. Many rotifers of two different types were there. Also this week I was able to observe two amoebas, which was the first time I had seen them as well! There are two pictures up of them, and it was such a thrill to watch them. They moved around, oozing their way over strings of algae and around other obstacles. It was fascinating to watch their cytoplasm stream around as they did so. There also seemed to be more air bubbles this time too, suggesting that there is some anaerobic respiration going on, and since the aquarium is not air tight, some aerobic possibly as well. I was also able to identify and observe many vorticella plants anchored all over the aquarium as well. There were two or three other organisms I have yet to identify that I hope to find and give the information on as well this upcoming week.
