For my second observation I started by replacing the evaporated water in the aquarium. Once I placed it under the microscope I looked at the place where the food pellet was resting and noticed 20-30 rotifers feeding on the pellet. I did not see anything new around the plants so I started to look at the soil. I noticed a worm looking creature that was near the soil siphoning/eating and moving in a side-to-side motion. I discovered that they are called nematodes; a threadlike worm that live in any sand, soil, or mud and are also sold by gardening firms to kill anthropod pests and insect larvae (Rainis and Russell 1996). There was also plenty of rotifers near the soil, but these were moving so fast it was hard to get a count of them. However, I did not spot any vorticella during the observation.
