On Thursday October 22nd I had the opportunity to observe my MicroAquarium once again. This time was far more interesting. This time I was able to see many things that were not visible the first time around.
This time I saw what believe to be didinium, which are small round organisms. The aquarium had many, many of these floating and moving around. It was also home to what appeared to be many colonies of small organisms. These colonies seemed to be parts of plants that would sometimes contain hundreds of tiny spinning creatures.
The arthropod from last week was still there, and I've learned that it is an amphipod. It has decided to create a small burrow in the silt at the bottom of the aquarium and eat any of the other organisms unfortunate enough to wander past.
