Last Thursday I observed my micro-aquarium for the last time. There was quite a bit of life and movement at the bottom near the dirt. I learned that the specks that are scattered everywhere are called diatoms, a major group of algae (Pennak 1989). Interspersed among the diatoms were many varieties of protozoa and rotifers.
This is a diatom called a melosira (Pennak 1989).
This is an acanthocystis (Pennak 1989).
An amoeba swimming around some diatoms.
Anisonema have two flagella on opposite sides. One is used to latch on to firm objects and the other propels it through the water (Pennak 1989)
Here is a broad view of the bottom of the micro-aquarium showing the large amount of cynobacteria that is growing.
The Euchlanis Rotifer has a forked "foot" that is used to latch on to a firm object (Pennak 1989).
I also found a few of these insect larvae. I was not able to identify the specific species they belong to. They preferred to stay hidden among the algae and dirt.
