Week 4, Final

My little tank's water levels were dreadfully low, and I worried at first that perhaps my cyclops and aeolosoma may have gotten caught out of the water and died. When I checked them out under the microscope, however, I found an aeolosoma wriggling about just fine, and eventually my cyclops was back to darting around, as well. There are definitely less amoeba now, and one of the bladders on the carnivorous plant, Utricularia gibba, is an oddly deep bluish-purple shade. I wonder if that means that that bladder died? When I tried to look up information on the matter, I mostly ended up sifting through lots of different types of the plant with different colored bladders, so that wasn't very helpful.

My cyclops did not want to stay still at all, but he seems to be about the same size as last week. I couldn't find more than one aeolosoma, though I'm not sure if the others have died or are just hiding from me. I can't really scour every last crevice of the tank for them, so it's very possible that I just didn't see them, but they certainly seem to be less in number, regardless. The very low water levels may be partially at fault for this. There is definitely less amoeba than there were at the start of the project, but I wouldn't necessarily say much less than last week.
