These boxes won't go away, I don't know why. Sorry.

Observation 11-12

In my aquarium, I can see where the microscopic creatures died. Their bodies are all over the plant leaves and all within the dirt. I have a few organisms left. A cyclops or so, a few shrimp, and maybe one annelid. The water in my aquarium seems to have slowly decreased over time. It doesn't come up to the near top like it did when I filled it. I don't think all of my smaller organisms actually matured into their larger forms because I don't see any larger ones. I was told that I had a baby cyclops, which I don't think lived past maturity. I am nearly positive most things died.

Observation 11-5

Not much has changed, one of the cyclops died. I found many carcasses of seed shrimp hidden amongst the dirt and plants. The diversity of my aquarium is dwindling down to 3 items:  Seed Shrimp, Annelids, and Cyclops.

This is a Cyclops, a Copepod. I found only two of them.

This is a creature I found in my aquarium. He is very common and is a Seed Shrimp, or Ostracoda.

Taking A Closer Look: Extra Observation 1

When I looked more closely at my aquarium and tried to identify the organisms with the help of multiple books and some professional help, I found many organisms that I didn't know I had in there. I found multiple "Cyclops" creatures and their earlier stages. I found some tiny shrimp and some annelids. My most profound discovery, though, was the "Pterodina Patina," which looks like a pot with a small mouth on top and visible organs inside. It was clear and transparent. It closed the small mouth on top when tiny particles got into its range.

Also, a piece of food was added to the tank.
