One week ago when the food pellet was put in there was an increase in actvity in the aquarium. The whole thing swarmed with rotifers but they were mainly concentrated near the food pellet. annelids started to apear in the dirt, they are the largest organism in the aquarium and mainly move around near the dirt. Now that the food pellet is gone many of the rotifers are gone and dinoflagellates have started to apear, unlike the interesting stuff they are staionary. The first picture is of a dinoflagellate, the second picture is of a rotifer and the thrid picture has an annelid in it.
