From 10PM until 6AM the power was out. The lights go out on the tanks at 9, so I forgot that the power out meant that the heaters were out. At 1AM I was up covering the tanks with towels to help them keep warmer (and shut the window they are right next to
). They got down to 72 for the 2 gallon and 76 for the cycled 5.5 gallon before I got the towels on. I took the filter media out of the filter at around 11 and put it in the tank to maybe help save my cycle. Just very frustrated. All fish seem to be just fine, I was mostly worried about my old man. Going on 2 years, he is noticeably more fragile than my two younger fish. So what is the best thing to do when there is a power outage? Other than forget your fish don't have heaters, of course.
