MicroAquarium Week 3

This week was an interesting one. First, Betta food pellets were added to the MicroAquarium. The name of the food is "Atison's Betta food" and is made by Ocean Nutrition, Aqua Pet Americans, 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% (McFarland). During the week, after the food was added to the aquarium the activity inside multiplied. There are many more tiny organisms moving very fast and also a lot of green algae or some kind of fungal growth composed of many filaments. I also notice an increase of actinosphaerium, rotifers, and snails, ciliates, heliozoans, flagellates, and many protozoa. The picture below show a snail feeding on plant B. I noticed many snails around plant B as well. They love to hang around and feed. I think the snails are the one watching and keeping everything under control inside the Aquarium.   




This one I just noticed and I am working on identifying him. I will get back to this one on Tuesday.
This guy here is not identify as of yet. i am not sure if a flatworm or a roundworm.
My view this week was very different to last week. Let me mention that the aquarium had less water inside, it is due to evaporation so I inserted some water to fill it up. I think that the process of putting the Betta food in the aquarium made everything gain strengh and all different kinds of organisims are appearing. The algae is also very big, it seems to be growing and growing, whcih is good because many of the organisms feed on dead plants, algae, and animal material.

Actinosphaerum

This is the video I mentioned on my last blog. This an Actinosphaerum digesting several rotifers. I noticed the activity after it has digest 3 and it was on the fourth. If you look closely you will be able to notice the last part of the rotifer being digested by the actinosphaerum. A Rotifer is a tiny multicellular aquatic animal of the Phylum Rotifera, having a wheel-like ring of cilia at their front end. The cilia traps small organisms for food. They are found in fresh and salt waters.

Week #2- MicroAquarium Project

Week 2
Actinosphaerium
My observations of the second week of my MicroAquarium project  is very interesting. First, I noticed the huge change in the amount of organisms in the aquarium, from snails, who were very active in digesting everything that came their way as well as many small organisms floating all over, especially around plant B.  The picture above is a multinucleated heliozoan that is related to Actinophrys. (Paterson, D.J. 1979). They are very small and are very common in fresh water as well as in lakes and rivers. They are unicellular and spherical in shape with a almost clear body and is filled with tiny vacuoles which assist in flotation. (Paterson, D.J. 1979). When I first noticed this organism I notice that it was moving very slow and at the same time it was digesting a piece of something, it almost looked like a vacuum. I actually took a video as it was happening, but I had trouble downloading it. As soon as get the problem fix, I will have it on my blog.

MicroAquarium Project

An inquiry into the dynamic microorganisms in our environment.
On Wednesday 13, 2010, I started my MicroAquarium project and it will be a weekly process for the next five weeks. I placed 1/3 of water into the aquarium, the first water was taken from the bottom of the container #4 which is water from the Holston River located along the John Sevier river under I 40 bridge. After I placed the first 1/3 of water from the bottom, I took another 1/3 of water from the center of the container and placed it in the aquarium, after that i took the another 1/3 of water from the top of the container as well a two different plants. The plants are Labeled A and B. Plant A called Fontinalis and is a collection from Natural spring at Carters Mill Park, in Knox co. This particular plant is a partial shade exposure as well as the water from the Holston River. Plant B is called Utricularia Gibba, and is a flowering plant and carnivous. The original material is from south shore of Spain Lake, east of Sparta, TN. This particular plant is grown in water tanks outside of greenhouse at Hesler Biology building at the University of Tennessee in Knoxville.
After I placed the water together with the plants in the MicroAquarium I looked at it under a microscope and what I saw was incredible. First, I notice a very small almost transparent organism swimming back and forth in a very fast mode and when not moving, it was feeding on plant B. On plant B, I saw 2 small bubbles and inside it appears to be another bubble except the bubble inside was darker and between them I noticed very small particle moving around. I also saw a long organism moving very fast near plant A which I believe it is a mosquito larva. I also notice one organism very small with an oval shape to it and that organism was also feeding on plant B.
