Fish Crazy
buy an air conditioner
What country do you live in? If your tank really was at 45C I am amazed that your fish have survived, I slow cook pork at 50C from raw to cooked.
I know it's hot in the UK atm mate, but seriously - where I am it's been about 30C outside and my tanks are at 27 with the lights and heater off the past couple days.
45C would be impossibly hot
