At the beginning of my last observation I once again replaced the evaporated water with water from a squeeze bottle at the front of the lab. Under the microscope I spotted 20-30 nematodes, about 15 lecane rotifers, and a lot of difflugia. Near the dirt in the bottom of the aquarium I spotted a very small organism that was moving in a sliding motion, back-and-forth, in one area very slowly. I discovered that it was called a Navicula sp. and they live on, but are not attached to a surface area (Canter-Lund and Lund 1995).
