Water used: Fountain City Duck Pond
Micro Aquarium observations for 17-21 Nov.
The first thing I noticed in my observation was a dead Dero, most likely the same one I found the week before. It seemed to be split in half near the head. Interestingly enough, there was a smaller Dero that I found very close by to the larger, presumably dead one.
Being the last observation, the micro aquarium seemed to be bursting with organisms, with activity everywhere you look. Not saying that there wasn't any organism activity to be found from the observation in the first week, but it will be interesting to find out if other micro aquariums have grown the same as mine.

Micro aquarium observations for 10-14 Nov.
Water used: Fountain City Duck Pond
Observations for 10-14 Nov
The amount of organism activity and density has shot through the roof since the aquarium has been created. I have finally started noticing dead organisms caught up in the soil at the bottom as well. There has also been large build ups of non-living, string like particles. They become very dense in some areas. It might be from the high amount of organisms moving around in the dirt, but it seems like the soil is breaking apart and dispersing. It is not as solid as it was last week and there are not as many good hiding spots for organisms that seek the cover it provides.
I saw my first Dero. It was a wormlike organism that was incomparably larger compared to any of the other organisms in the aquarium. It was far too big to view the whole thing at once. The movement on the inside of the organism was unique, creating a wave that went down the length of the organism every couple seconds.

Micro aquarium observations for 3-7 Nov.
Water used: Fountain City Duck Pond
Observations for 3-7 Nov.
After 4 weeks since the set up of my micro aquarium, it is clearly much more dense than what I have observed in the previous weeks. The larger, multi cell organisms, mostly oval shaped rotifers, have become much more comfortable roaming in areas outside of the dirt. I also saw that they usually stay grouped together. The aquarium is mostly taken up by rotifers, with other organisms, single and multi celled, mixed in. There were also several clear, worm like organisms that moved in sporadic twisting movements with it's flagella. However they did not seem to go very far distance wise. Most of the plant life was green algea. Overall, the aquarium is filling with more of a variety of organisms and behavior.

Micro aquarium observations for 20-24 Oct
Water used: Fountain City Duck Pond
Observations for 20-24 Oct
After observing my micro aquarium a week after it was set up, there was a huge difference with the quantity and volume of both large and small organisms. The larger, multi cell organisms are more active and move outside of the soil more often. The most dominant were a collection of approximately 10 long, skinny organisms that, for the most part, move more quickly and radically with out a sense of direction. They stayed near the bottom, but not necessarily staying in the soil. There were a few very large organisms that were particular to staying in the soil. They moved slowly and appeared to be digging or feeding. I saw one large, clear, multi cell organism with 4 "legs". It stayed still, with the exception of lighting fast movements every now and then. All of the larger organisms still stayed in the bottom of the tank, and the small single cell organisms were still found moving in a slow, lazy fashion in all areas of the aquarium.

Micro aquarium observations for 13-17 Oct
Water used: Fountain City Duck Pond
Observations for 13-17 Oct
I created my micro aquarium with water and organisms from the Fountain City duck pond in Knoxville, Tennessee. Small samples of water and soil were extracted and placed in a small, clear slide using a pipet. The plants Amblestegium varium and Ultricularia gibba were added to provide oxygen and diversity to the aquarium.
The observations after immediately setting up the aquarium were interesting. There were already small, single celled organisms moving around all areas of the aquarium and larger multi cell organisms moving around in the bottom of the aquarium. They stayed in the soil, presumably feeding, infrequently coming out just to go back in the cover of the soil again. I am interested to see the changes in size and variety of the organisms next week.
