Day 2

First observation of my MicroAquarium was that there had been some water loss, about 1 cm.  I also observed many of the same small organisms noted during Day 1, now identified as seed shrimp.  The seed shrimp are found in all parts of the aquarium, they have no specific preference.  I also observed several dead organisms at the bottom of the aquarium.  I also saw one water bear.  I observed two flat worms, Planaria sp (Ward and Whipple, 1918) . One of the flat worms had managed to eat a seed shrimp. Both of the flat worms were located in or near the soil.  I saw a couple Jacks by plant A.  There were several cyclopes, most by the surface of the soil.  I also observed and videoed a rotifer, Pterdina sp (Ward and Whipple, 1918).
