So my Oscars and I were finally gelling. I bought a better filter water was clearing ich was clearing life was good. I came home from work only to find a heater malfunction had fried my fish. The thing was set at 82° and the mercury thermometer read 112°. I am in shock and my feelings are so hurt. People told me my first batch of fish would probably die. I might have been ok if I killed them. But the dog gone heater did them in?? Grrrrrr
