My first observation of the week for my microaquarium was made without a microscope. I noticed upon picking up my aquarium that bubbles had formed. Some tiny little creature in there is producing gas. It took me a few minutes to find my first organism. I noticed that there was a sharp decrease in the amount of aquatic inhabitants.

Spirogyra sp. was a species of algae living in my microaquarium.

Stylaria sp. was the second organism I found. It lives in freshwater sources.

 *Note the hair on the body of the Stylaria sp.

*The snout on the head of the Stylaria is a distinctive feature of this species.
