I came home from work today to find two of my most prized predators dead... my african brown knife, a 6" fish I've had for over three years, and my 5" pictus catfish, who I've had for slightly less than three years. The rest of my fish-- two severums, 5" a piece, a nandus, 4", a senegal bichir juvie, 4", and three silver dollars at 3-4" all look like death warmed over. The only one that seems unaffected is my African butterfly. I tested the water parameters. Ammonia and trites are at zero, and trates were around 50, which is normal for a Friday (water change day). Temp is stable 76 degrees as always. The tank is a 75 gallon, with plants.
I can't for the life of me figure out what the hell went wrong. All the fish were perfectly active and happy on Wednesday when I fed them their live blackworms and sinking pellets, and now two are dead and five others look about ready to join them.
I changed NOTHING in the tank, there are no marks on any of the fish, nor had I added any live food other than worms recently. I did a 40% water change, and am going to try another in about two hours.
What else can I do?? What went wrong? The only thing I can think is that last night I did two loads of laundry without realizing that the hose on my dryer had come partially detached. I only noticed it when I walked down into my basement (which is my combo fish and herp room) and the temp was way warmer than usual. This is the ONLY thing I can think of....
