observation three 10/26/2010

This week a "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%.) was added to the micro-aquarium. 


Observation: The numbers of individuals in the communities was greater today than it had been over the last two weeks.  This could be a response to the abundance of nutrients resulting from the addition of the Betta Food that was added.  Also the number of individuals out in the open was greater this week then in the las two weeks.  This could also be a result from the Betta Food.

  The image to the left is a Vorticella found in Ciliated Protozoa fig. 4A. Vorticella are usually bell shaped and long tails which they use to attach to fixed objects.  They feed by sifting for nutrients through the open end of the bell (from Transactions of the American Microscopical Society)
