Week Four

This was the last week of observation.  I was surprised at just how much my tank had changed over the last month.

The Utricularia gibba L. had all died but the  Amblystegium sp. had flourished.

The food pellet eventually fell to the bottom of the tank and was mostly disintegrated.

I saw a lot more colopse this week than I have in the past, although I could not find any vorticella this time most of the water fleas seemed to have died.

We did make one new discovery though.

Adult Midge- Family: Chironomidae.  Commonly used as fisherman's bait.  (TCHP 2012)
