Week 4

Things changed a lot this past week in my tank. The Rodifers (the little round things) have almost disappeared entirely. They were swarming the place last week. I cannot figure out what has happened to them. I'm quite disappointed that the activity levels have decreased so much. I was enjoying all the different organisms bouncing around. I was able to find some amoeba still but was unable to find my flatworm. That too was not a great thing. The flatworm was my most favorite organism. I really hope he was just hiding out and hasn't died. The water in the aquarium has gone down as well. I'm not sure if it is evaporating or if someone knocked it over. I'm fairly certain evaporation is the cause.
