At this final observation, the water level is very low. The aquarium is drying out. Paramecium are still abundant, but not as many as last week. There are still a great number of seed shrimp, Vorticella, and diatoms. Phacus triqueter numbers have increased. Generally, there is less activity in the upper half of the tank. A difference I notice is that there is much more debris at the bottom of the tank, but most impressive is the activity in the mud. Seed shrimp are digging around, funneling material through their bodies.
It has been interesting to see the changes in my MicroAquarium over these five weeks. There have been changes in type and number of organisms, growth, and activity. This has been a chance to participate actively in true science study, experimentation, and observation.
