*On Friday, October 26, 2012 one Beta Food Pellet was added to my MicroAquarium.
"Atison's Betta Food" made by Ocean Nutrition, Aqua Pet Americas, 3528 West 500 South, Salt Lake City, UT 84104. Ingredients: Fish meal, wheat flower, soy meal, krill meal, minerals, vitamins and preservatives. Analysis: Crude Protein 36%; Crude fat 4.5%; Crude Fiber 3.5%; Moisture 8% and Ash 15%. (McFarland 2012)
I was able to identify the food pellet and noticed that there were quite a few small organisms swimming around it.
There was a lot of movement today! The organisms were small but they were swimming around very fast. They were mostly found in the middle of the tank but the top and bottom had a few drifters as well.
I was only able to definitely identify one organism. That was the Vorticella
Vorticella-
-Located near bottom on fern.
-"A common peritrich ciliate. The only cilia that are present are the weathers of feeding cilia made of an upper band, which corresponds to a membranelle and generates currents of water for feeding; and a lower band which corresponds to the undulating membrane. Food is passed through a buccal cavity before being packaged within food vacuoles. Many peritrichs are supported on stalks. This makes the vulnerable to predators. Some protection is provided by stalk=contractility, afforded b a spirally contractile thread or spasmoneme. The contractile elements of the spasomneme pass into the body. Differential interference contrast. (Patterson pg 113)
I used the BioCam posters to make possible identifications for some of the other organisms that I saw. Here are my hypotheses:
Lots of small swimmers- Protozoa maybe? Colpidium?
Large complex organism- Located in middle. Maybe a Daphnia?
