After spotting the rotifers I noticed that there was a lot of movement near Plant B. When I focused on the movement I saw what appeared to be a little colony of tiny green organisms moving in a circular pattern inside the plant. I was told that they were paramecium in a a disintegrating bladder on Plant B (McFarland 2010).
I then spotted a Vorticella sp. that was attached to the plant and looked like it was filtering water through its "mouth", these protozoa feed on bacteria and small algae (Bick 1972).
Finally, on Friday (10-22-2010) one pellet of "Atison's Betta Food" (made by Ocean Nutrition, Aqua Pet Americas, 3528 West 500 South, Salt Lake City, UT 84104.
