fourth observation

A huge population of Roiterfiras were found. In quiet waters Haltaria which was in the phylum of Ciliophora known as ciliates. In the class of Spirotrichia(spirochs) in the genus of Halteria. Hordes of these bouncing ciliates were found annual water cultures. Microannelids such as Chaetogaster, Stylaria, and Tubifex were possibly found (Guide to Microlife pg.21, 167-09). Actrinosphaerium from pond weeds. Inside is a large central object which is a food vacuole with two smaller meals that are digested in it. The basic description of an Actinopoda is that it is 70-80 um in the phylum Actinopoda and genus Actinosphaerium. It's star shaped with a very small membrane-like compound (Guides to Microlife pg. 82). I also noticed that activity in the aquarium improved with its network or micro plants and organisms.

part 3 obs.

The third observation featured not much activity with less movement. Though new types of Ritoferas were found like the genus Ritofera (pg.179-193 Guides to Microlife). Microoganisms were moving very fast around which made them hard to identify. I found that dead plants like algae cluttered in most areas which in this case were Diatoms from the phylum bacillariophyta in patches. I found flagelates Phacus(pg. 67 Guides to Microlife-Kenneth G. Rainis, Brues Russell). Speaking of microorganisms they were moving diagonally. To find the organisms was hard like the thread-like worm Nematoda or Nematodes because it was moving around and hid (pg230-233 Guides to Microlife'''). An Urocentrum which moved in a circular mannerwas found as well ( pg167, Fresh Living Freshwater Protozoa:a colour guide/ D.J. Patterson).

day 2 obs. more activity

There was a lot of activities and more organisms were event. I saw paramecium aurelia moving under a plant root. Litonus which moved around(pg.133, Free Living Freshwater Protozoa, D.J. Patterson). Frontona which is related to Paramecium was also found. Several Rotiferas including a shell Rotifera were found ("microlife" p9. 179). A Gastrotrich which had two tilas was found ("MicroLife pg.177).
