3rd and 4th Observations

On my third observation, I saw more of the same. The same organisms were were doing more of the same actions. There seemed to be smaller amounts of the larger organisms. I had to look harder and longer to find specimens in my tank.

Although there were smaller amounts of larger organisms, there was an emerging number of smaller oragnisms. More green plant life seemed to be growing around the inside of the tank as well. I did observe several rotifers.


On the fourth observation, there was a large number of smaller organisms. The larger organisms were next to impossible to find. It did not seem that my tank had lost any water, but I found it interesting that the organisms that were there before were not there at the fourth observation. I was only able to find one large organism on the last observation. I believe the snake-like organism that I observed in an earlier sitting was a Midge Larvae. It was dead in this last observation. I could not tell if it had gotten stuck to the side of the tank but it was not moving and seemed to have no life left.The piture below is the Midge Larvae.


The large number of smaller organisms seemed to be a type of flagellated protozoa. These organisms seemed to make up the majority of organisms in this last observation. The rest of the organisms seemed to have "vanished" in a sense.
