Week 5

Since my last observation there has been even more of an increase in organisms. Inevitably, there is also an increased of dead organisms. The microaquarium seems more busy, and also slightly more messy. There is also an increase in the cyanobacteria that was spreading across my aquarium last week

Week 4

Here is a video of Litonotus sp. that I found in my microaquarium. There were several of these little guys. This one appeared slightly different than the others because it had recently eaten, and you can see its meal in its stomach. Another interesting thing to notice is the vacuole that opens and closes.

Here is a pretty good picture of the Litonotus sp. featured in the video above. You can see that there are several cilia along its long neck. In this image its vacuole is open.

Week 3

Since last observing my microaquarium, a thin layer of filamentous algae has appeared. The algae is primarily under the plant at the top, and it is denser towards the bottom of the aquarium. The number of organisms has increased, and there are a few dead organisms in the bottom layer of the tank.
