Weekly Observation 10/23

231739Z Oct 2009-

Actions: Today I oserved and identified(?) several organisms and structures. I added additional water and one food pellet upon completion of my observation period.

Observations: The picture you see in fig. (1) is a bladder on the plant which is full of paramecium. I observed several of these bladders with varying amounts of activity contained within. Cyanbacteria have begun to grow throughout the aquarium. The strands are captured in figure (2) along with what I thought was a Philodina (3)but I have since changed my mind. I will update that indentification on the next post. I observed a Ciliate which I most closely identified as Colpidium (4). I utilized "Fresh Water Protozoa" by Patterson to guess at Colpidiums identity. I observed two Ameobae and some fast flagellates along with what I believe to be a Desmid.
Comment: I am somewhat disappointed thus far in the amount of diversity contained within my aquarium. I observed no insect larvae or other "large" organisms. I look forward to next week and the potential effect the feeding pellet has on my overall observable biodiversity. Talk to you next Friday.

  1. I'll be anxious to see if your diversity goes up now that you have added the food pellet. Do you think your water source might be the reason you don't have large microanimals?
