In this weeks final observation, I seen two organisms that I have not seen.  The first of these two organism is a Euchlanis, which is an ordinary rotifer that moves all throughout the aquarium.   There was not a particular area that the Euchlanis was found in they were everywhere.  I also noticed that they were feeding off of smaller substances.  The second organism was a Nematoda.  I was not sure of which specie name it fell under so we decided to lable it with its genus name.  From what I could see there were very slim amount of nematods in my aquarium.  The only information I have on these oraganism is that they opperate as like wise of a typical worm.

In this weeks blog I found two organisms that I have not been seeing commonly.  The first one is this in the picture above. Its genus name is Centropyxis, it is found in the amoeba group.  What we can see of the amoeba is just its shell.  The organism is secreted to the glass of the microaquarium.(Patterson 2003)

In this weeks observation, I have seen a rapid rate of growth of all my organism inside.  However, all of the organism seem to be seperated into different sections of my microaquarium.  It is stunning to see how by the addition of the beta fish pellet, BFFP,  has increased the size of the organisms.  The correlation to the pellet and the organisms could be that it is supplying the microaquarium with vast nutrition and the organisms should continue to grow in size if my hypothesis is correct, considering there is still a vast amount of the pellet left (McFarland 2012).  I was unable to take pictures in this weeks observation, so hopefully next week I will be able to have many pictures of how the organsims have evolved into what they are now.

On this week observations, I found and named many organisms.  The image above is a Urocentrum.  This specie behaves a little like a spinning top in the way that the bottom stays central and still while the top spins rapidly and causes the movement of the organism.  This organism feeds off suspended bacteria and is very closely related to paramecium (Patterson 2003).  I can tell just from the two observations that my microaquriaum is growing and increasing in activity.  So far from what I see my aquarium is very diverse and composed of many organisms.  We will see how the Beta Fish Food Pellet reacts to the aquarium in next weeks post.

When we set up our microaquriums, I used the bottom sufface of the french broad river.  After that I placed both plants A, Amblestegium sp. Moss, and plant B,Utricularia gibba.  After the set up we placed the aqurium under the microscope in search for organisms.  I am not sure of what the organisms I found are, but I do know that they are mainly located at the bottom and middle of the aqurium.  They are also free moving and feeding off of the plants that I placed into the microaqurium.  The movements of these organisms are spinning in a circular motion.  Next week I will observe the organisms to see if they have grown and see if they are still the same.
