That wasn't a good day for me! Canada with a tank full of dead fish...have learned that is the risk with this great hobby of ours...happen back in 2004...no clue what happen...no water change the night before and or any changes to my routine...continues to be a mystery...but moved on...
One of my older fishes died tonight it was sad i got home and my kittens had unplugged the power cable that runs the air pumps. Once i noticed the power out i checked the tanks and in one a 6 year old oscar named Einstein bit the dust poor guy via lack of o2 with the pumps not running. Freakin lame. When he was younger i taught him to jump all the way out of the tank and grab food from my hand.
