I have 75 gallon full reef. In the winter in the past, I've have gone 5 hours with no power. Tang, couple clowns, royal Gramma, wrasse. Temp down to lower seventies.I have a 75 gallon display and 16 gallon sump. The power was out for about 2 hours and I was worried about the oxygen and the temp. I only have 2 clownfish in there right now. How long can they survive in there if power was out for 24 hours? Is temp a major problem when the power is out and the temp drops 10 degrees? Thank you
I once had a mishap with a blue star wrasse. I was cleaning the sand in my display and he managed to get scooped up and thrown in a 5 gallon pail. Of course it was late at night and I was tired, and I put the pail in the basement. It's only about 65° in my basement. The next day I finished my task at hand and rinsed all the sand in tap water. And then I saw the wrasse swimming in freshwater after being in 65° sand with barely any salt water. I scooped him up and threw him in my display. He lived for another year or so. I think fish are a little more resilient than what people give them credit for.
