There are even more tinier microorganisms found in my aquarium upon the last observation, mostly ciliates, worms, and diatoms. Gastrotrichs are the most abundant aquatic animal spotted this week in my aquarium. Bacteria and algae, specifically green and blue green algae, have also taken over the aquarium.
As you can see in this photograph, cyanobacteria (the small blue green strands) fill the areas between the plants along with bursts of green algae. There were small signs of spirogyra also found in less abundant numbers than the other cyanobacteria and green algae.
Spirogyra can be seen among the brown dirt areas. Vorticella aren't as abundant as they were in the previous observations and instead the aquarium is overrun with bacteria and algae. There are also hundreds of tiny green pellets scattered about the aquarium, which could be bacteria. Although I assumed ostracods were mostly extinct from my aquarium, I found a few more than last time, even one lively one scooting along a stem of Plant B. I've discovered that there is much more variety in the new abundance of bacteria and algae than in the aquatic animals observed previously. The vorticella has mostly moved to the surface of the dirt rather than among the plant stems. Inside of the originally observed pods among the stems of Plant B there are hundred of small green wormlike creatures vibrating within the pod.
A (rotifer) that hasn't been spotted before was seen around Plant B, slow movement and a rotating mouth.
