Fourth and Final Observation 11/11

With this being the last observation I decided to disturb the environment a bit. After looking with the dissecting microscope which provides a more 3D experience, I shook the Micro aquarium and used a fine point needle to move the soil around. Once I placed the aquarium back under the dissecting microscope a very large midge larva was exposed. Moving widely and very violent this little guy was a pain to keep track of. Under the protection of the soil this organism was seemingly a slow moving creature, but once exposed to the open space and light became wild and chaotic. Very hard to capture a good picture of but I did mange to snap this one.

 Eventually the midge larva will evolve into a mosquito like insect. pictured below the speckled midge Tanypus Carneus.

Third Observation 11/4

Oddly fewer numbers of organisms seemed to exist this week. The Cyclops, Seed Shrimp, Algae and Rotifer still remain and plenty active. Below you can see a few pictures of these organisms.

The following video is a large Vorticellum mass. This mass of organisms is very sensitive. The explosive point in the video is when Dr. McFarland slightly tapped the microscope.

 

 

 

Second Observation 10/28

Right off the bat I noticed that I could with my naked eye see things moving in my micro aquarium. Turns out a very large seed shrimp, very mobile and noticeably did not enjoy the light of the microscope. On Friday October 21 a single beta food pellet was inserted into each micro aquarium by Dr. McFarland. The food pellet was a "Atison's Betta Food" made by Ocean Nutrition, Aqua Pet Americas. Located at 3528 West 500 South, Salt Lake City, UT 84104. The Ingredients in the food pellet are fish meal, wheat flower, soy meal, krill meal, minerals, vitamins and preservatives. Some analysis: Crude Protein 36%; Crude fat 4.5%; Crude Fiber 3.5%; Moisture 8% and Ash 15%. This explains the increased size in many of the organisms like my Seed Shrimp. A noticeable amount of soil is gone from the aquarium, possibly consumed. With the help of Dr. McFarland a Cyclops was Identified. A very small cricket like creature. Very fast and hard to track with the microscope. They jump from place to place and their kill is quick and fast. The two fern additions to the aquarium have started to develop large sac like structures on them with very small organisms moving about on the inside. Pictures next post!
