As the water levels in my aquarium continue to get lower, over all i'm noticing that plants A and B look a bit more shriveled and less green than they started out. Especially Plant B which has lost almost all of its color and mass.

Starting by looking at plant A I noticed it appears darker and less leafy. The MicroAquarium has an abundance of rotifers which are completely covering Plant A and all the area around it. Included in the area around plant A is a lot of debris that I cannot identify the source of. The biggest question I have is- Do rotifers reproduce and if so, is the debris i'm seeing eggs or a byproduct of the reproduction? I ask this because that is how it appears and I also see many even smaller organisms moving around that do not have a distinct, identifiable shape.

Most rotifers are female and reproduce asexually by laying eggs. This is rather unusual considering that rotifers are considered animals, and it is unusual for animals to reproduce in such ways.

I can conclude from this information that indeed, my rotifers have been reproducing which is the reason for the debris and many baby rotifers now inhabiting my MicroAquarium.

(My information on rotifer reproduction was found at: www.ucmp.berkeley.edu/phyla/rotifera/rotifera.html)

In contrast to last week I was only able to observe on tachysoma in the MicroAquarium this week. I'm sure there were more that I couldn't observe but the abundance of rotifers definately made the tachysoma less obvious and less easy to spot.

In plant B I observed a few organisms that I could not identify although they looked like dandilions and had a similar look as the actinosphaerium. They were white in color and immobile and sitting amidst the plant making it inconspicuous and hard to spot.
