I just went downstairs to wake up my fish when I got the shock of my life. The tank water was so cloudy I could hardly see and then I saw my fish. They were all dead. I am devestated. I have had these babies for 7-10 years. I don't know what happened. When I went to bed the water was clear and they were fine. How do you deal with feeling guilty, it must be something I did, to wanting to quit, and the grief, they were my pets?
