MicroAquarium Observation November 6th Observation

The 4th week of observation is now under way and the most noticeable difference between week 3 and 4 appears to be life witin the MicroAquarium has plateaued to the same level as week three.

There appeared to be no noticeable creatures found this week as opposed to the previous week as various rotifers, diatoms, green algae, and nematoads were all observed easily at 10x magnification.












Other noticeable observations with the naked eye include reduced water level, which should expected in this junction of observation, the remanant food plot of the previous week was now gone, and plant B was now noticealby more resisant to the effects of aging than plant A.

What I feel is one of the most interesting creatures in my MicroAquarium is the Rotifer (as seen in the photo below). Rotifers are multicellular animals that are 200-500 micrometers long (www.ucmp.berkeley.edu/phyla/rotifera/rotifera.html) The name Rotifer coming from the latin word meaning "wheel-bearer"(internt.nhm.ac.uk/jobj/runjava.jobj?java=ctol.CTOLServer&method=printNamePage&accountref=987&NAMEID=13689.

As the last week of observation approaches, it could be assumed that due to this weeks lack of new organisms that next would not be any different. I attribute the productivity of week 3's observations to the food pellet, without the food source the MicroAquarium is not as productive.
