These Rotifers are also very present in the MicroAquarium. I first saw them last week although there was only one and it was much less active than they were this week. They were also spread throughout the aquarium instead of being located in one central location like the actinosphaaerium below.

This organism is called an actinosphaerium. It was found around the outer edge of plant A where the plant is less dense, yet it was not free-floating in the water. The radiating flagella help the organism to move and function around the aquarium.

There is also an abundance of these organisms in my MicroAquarium. The tachysoma were found in the soil, moving around in the water and around the plants. Their long bodies and cilia helped them move around the aquarium quickly and efficiently.
