My power just went out, and they don't know when it will be back on (maybe 2 days, three poles are down). It's dead winter and FREEZING, it's 55 Fahrenheit in our house currently (dropped 10 degrees F in 2 hrs). I even have my goldfish tank wrapped. What can I do with my betta? He has no heater and neither my betta nor the goldfish have filters. So far the betta tank is around 78-ish degrees F, (can't see the colors under my flashlight as well) so it's dropped just a little bit. I have both tanks wrapped with sweatshirts, with a few air holes. They'll be ok for now, but if the power doesn't come back in the next few days what should I do? We don't have a generator, btw.
