My tank temp dropped significantly in the spring when I had a 24h power outtage. I only lost two fish and a few corals. I was expecting much worse. It may surprise you how resilient some organisms are.
Totally agreed. I had a heater break on a 30 gallon once. The temp went down to 56 F from 79-80 F (sorry... all my stuff is in Fahrenheit). Everything but a clam survived.
I've got my fingers crossed for you mang.
