The biggest difference since I last saw my aquarium is the developement of a new algae. This new algae looks like short nylon hairs and literaly everywhere, never before in the aquarium has there been so much of one species as there is now. The eugenoids and the rotifers are still present but their numbers have significantly died down and the euglenoids have stopped moving which may be a sign that they are dieing out. I have managed to identify a couple Arcella, they are this yellow-orange ball looking blob that does not move. Arcella is a testate amoeba. The most prevelent moving organism is Dileptus, Dileptus is a predatory cilitate and I believe that it is to blame for the dieing out of other organism like rotifers.

The aquarium has not changed much since the last post. Sadly the analid named herbert passed away along with all of the worms the lived in the dirt, now there are new ciliates, I have been able to identify paramecium and spirostomum and there are many other kinds of tiny cilitates that can't be seen very well. the entire aquarium is slowly being filled with colorful specks that I think are mostly algea.

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.
