Week 3

The first thing I saw in my MicroAquarium Friday was the dissolving food pellet, so I looked at it under the microscope and found thousands of tiny organisms swirling around the food pellet. They were all too small to see up close on that microscope. I was scanning around and I saw the same rotifers as last week in larger numbers, still around the leaves of the plants. I saw the translucent worm-like organism again but this time it was not buried in the bottom, it was squirming around in the open water. Mr. McFarland informed me that it is called an annelid. One very interesting thing I did observe were some cool-looking tube-like things sticking up from the dirt in the bottom. I asked Mr. McFarland what they were but he wasn't sure, so I started looking in some books to figure out what this thing was. I couldn't really find out exactly what it was but I think it might be an immature Collotheca. Hopefully, when it matures I will be better able to identify it.
