There were also still multiple Vorticella on the dirt line (Patterson 1982). The Vorticella are multicellular and not mobile.
Also in the dirt line were multiple unidentified diatoms. There were a few smaller organisms though. Multiple Bodos could be found swimming around (Patterson 1982) . They swam smoothly around the middle part of the aquarium with two small tails. A few rotifers were also swimming around the middle and top part of the tank, but it was a significantly less number than could be seen at the first observations. Overall, the first week was very uneventful, but the following weeks came with more action up until the 4th week. Last week and this week were much less eventful because many of the organisms have died. Some of the dead organisms can be seen littered at top of the dirt line.
