Our hometown had a major ice-storm and 8 inches of snow on Christmas. Around 9:30 pm on Christmas Day, our power went out and as of now (around noon on the 28th) it still isn't back. Without their heaters or even the furnace running, the water in my fish tanks got dangerously cold pretty fast, so I was doing partial water changes every few hours and then covering the tanks with towels to keep the heat from escaping too quickly, but that wasn't working very well because the house was just so cold. Then our pilot light went out, so there wasn't even hot water. We evacuated the fish to a friend's house yesterday, and my Mom drove there again this morning to charge her phone, and she said all of the fish seem to be doing fine. None of them are showing stress and my tail-biters haven't even done any damage.
The rest of the family went to my aunt's for our annual Christmas family reunion, but my Mom is staying at home because she wants someone to be there to clean up the fridge and all when the power comes back on, and she doesn't want to leave the cats alone either. She said that the newspaper says it might be several days more before we have power because there are just so many homes without power that it'll take the city that long to do all the repairs. So we're still worried about my Mom and the cats, but it sounds like all of the fish are going to be fine.
