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.
