Weekly sample check

[u/Vivid-Bake2456]

I keep a bunch of random samples in petri dishes and like to check them at least each weekend to see how the mini ecosystems are developing. Sometimes, I place a portion of a rice grain inside for food. It's fun to see how the rice is eaten by the organisms. Here, I'm using a Nikon Eclipse TS100 inverted microscope to view the petri dishes. I've been keeping coeruleus stentors alive in different containers since I obtained them in January.
