Last Look

I had my last observations this Friday.  The thing that surprised me most was the amount of cyanobacteria that had grown throughout my MicroAquarium.  I had noted the increase in cyanobacteria each week, but this time it had grown completely through my aquarium.  It was everywhere I looked.  Also I forgot to add last week that I noticed the food pellet had become separated from the water sample by an air bubble.  I did not expect this to affect the MicroAquarium much, but this week I did notice a lot of dead paramecium and not as much life.  I identified a bunch of the algae I had been seeing throughout the weeks as diatoms.  As usual paramecium bursaria we're floating around everywhere.  I saw some flatworms and a rotifer swimming around as well.  I searched around for the vorticella I had seen the past week but to no avail.  I saw a lonely gastrotrich roaming around instead.  I followed him around for a while, before looking at an interesting stenostomum flatworm foraging around the Utrichularia gibba for something to ingest.  That's about it for my last observations. I had a good time studying the happenings of the MicroAquarium throughout the the weeks, and I'm a bit sad that it's over. Thanks for reading!
