Final Week of the Microaquarium

So today, I noticed that the water had majorly evaporated. It was only about 3/4 filled of the amount of water I originally placed in it. Plant B still had no life around it, it was slightly brown, it still had bladders though. There was not as much action around the Beta protein thing Dr. McFarland placed in the micro aquarium. My hypothesis is that it did its job and the organisms ate the life out of it. I saw lots of paramecium barsaria. Plant A was not as lively as last week. It appeared to be slowly dying. I saw and ostracoda. The image below is an ostracoda, or more commonly known as the "seed shrimp."

To see another image to and to learn about the seed shrimp see the citation at the bottom of this blog.

I also saw a Rotifer in my micro aquarium. There is a picture below of it as well. 

This is a rotifer, to learn more about it and to see other pictures see the citation at the bottom of this blog. 

I did not see the annelid or snail, there were still a few nematodes. In conclusion, it looked like my micro aquarium was evaporating and dying.

Week 4 of the Microaquarium

I noticed that most of the live action was thriving near the thing Dr. McFarland inserted. I found two long nematodes this week. They were near each other and near the inserted object (sorry I cannot remember what this is called). I saw a new organism this week. I noticed two flatworms near the bottom of the tank. This was surprising to me,  I had not seen them before. I took note that Plant B side was pretty much dead this week which is unusual but I'm guessing everything moved to Plant A since Dr. McFarland inserted that thing. Plant B look a little deader too. It took to have lost some of its green color, it was more of a brownish color this week. That's about it for this week. 

Week 3 of the MicroAquarium

On Friday, October 22, 2010, Dr. McFarland added one Beta Food Pellet to our micro-aquariums. 
Information on this beta food pellet is listed below. 
"Atison's Betta Food" 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%.


Today I saw a large blueish colored ball on Plant B. Dr. McFarland and I discovered that it was a bladder. I did not know plants had bladders, but they do. I saw many more bladders on Plant B but I noticed that the others were green, not blue. I saw the nematode again. This time I saw a few nematodes. Dr. McFarland also noticed a seed shrimp in my micr-aquarium. This was new to me, I had not seen it before. I also saw a snail. It was on Plant A. This was the first week I had noticed it. It was pretty large. I still concluded that there was more action on Plant B, but Plant A had more than usual, because the Beta Food Pellet was on that side. There was also more air bubbles throughout the micro-aquarium.
        Bad news, Dr. McFarland and I believe the annelid passed away. We saw no remnants but could not find the annelid and it was rather large last week. This could be due to the fact that I accidentally spilt some water out of the micro-aquarium onto the lab floor, the annelid could have fell out. :( I added more water. I have spilt the water twice now, so there may be a few more critters that will not be in there next week. 

Week 2 of the MicroAquarium

Today I saw an Annelid in my aquarium. I did not see it last week. An annelid is a legless and segmented organism. It moved slower than the nematode, but could move fast at times. It was also filled with red dots. I again saw some smaller single-celled organisms that were transparent. I saw some multi-cellular organisms, too. I noticed one green colored organism. I was not sure what kind it was. I also gathered from watching my aquarium today that the organisms seemed to be more around Plant B than Plant A. I also noticed a rotifer in the water.

      This is the tail-end of the Annelid.

Setting up the micro aquarium

Set-up Procedure: We obtained a glass tank, stand holder, and lid. We then placed three different colored dots on the glass tank to distinguish our tank from our classmates' tanks. The top colored dot represented our lab section. The middle colored dot represented the table we were at during lab and the last color represented the seat number at our table. We also put our initials on the dots too distinguish our own tanks even more. We then used a pipet and extracted water from one of the provided containers.We extracted water first from the bottom layer of the container and filled our tank 1/3 full, then we gathered some of the water from the middle layer of the container, filled our tank 1/3 full, and then the top layer again filling our tank 1/3 full. We then put our tank on its stand and placed Plant A and Plant B in our tanks.


Water type: 8. Tennessee River at boat ramp across from Knoxville sewer plant. Neyland Dr. Knox Co. Knoxville TN. Full sun exposure. French Broad and Holston Rivers water Sheds N35 56.722 W83 55.587 813 ft 10/10/2010 (McFarland 2010).


I observed by looking through a microscope at my aquarium both stationary and moving organisms. There was a nematode in my aquarium and it squired first fast. I also had some single-celled organisms and they moved more slower almost stationary. I had multicellular organisms that moved in swimming like positions. My aquarium involved both chlorophyll green and non-green organisms, but I had more non-green organisms. It looked like the organisms preferred the middle habitat of the aquarium. I only saw one nematode. I saw many single-celled organisms and quite a few multi-celled organisms as well.
