I'm so sorry to hear this. Just last night we wrapped all of our tanks in the thick window plastic because a big snow storm was making its way up here. Luckily, none of the power went out, but I'm glad we prepared in case it did. My dad lives about three hours away and has a generator. He's told me before he will drive up here and let us borrow it, or us drive down and go get it. I'd do whatever it took, but honestly can't afford my own generator, they are SOOOO expensive. But I guess you have to weigh that against how much you have spent on these fish you could lose.
Anyway, I'm glad you at least have one survivor, it's a pretty amazing story.
