October 30th Observation

On Thursdsay October 3oth I observed many changes in my microaquarium. In the picture shows a Euplotes,which was the first organism I spotted. The Euplotes were many in number and were transparent with cirri which helped them to walk along the plants. They would move swifty and then stop as I saw thier vacuum like mouth suction in food.

While watching the Euplotes,I also spotted many Paramecium swiftly move across the aquarium.The Parameciums were what I saw more than any other organism. They looked similar to the Tubelleria I saw in the previous week,but the Paramecium were much bigger and without eye socket indentions. On the back of the Paramecium I noticed black spots,and when research,realized were food vacuoles.

Perhaps, the most interesting organism I have seen in my aquarium observation is the Urocentrum. They spin around in circles like a top,and feed on bacteria. I tried to take a picture because they were so fascinating,but they moved too fast to capture thier essentric behavior.

The last organism I noticed was the shelled Rotifer,which were a moderate size, but not small in quantity.I would best describe thier shape as like a corn kernal with a tadpole like tail,and they move at a moderate pace.

In conclusion: I was a bit confused why I could spot any of the previously spotted organisms,and couldn't see dead organisms at the bottom of the tank. It could be possibly that they were hidden in the dirt at the bottom of the aquarium.
