Even in South Florida, with the heat at 71, my tank dropped four degrees overnight. It’s under the range I think is best for bettas. I turned the heat up (RIP my wallet) and changed the lighting schedule so it turns on earlier and helps warm it up. Our power losses here tend to be in summer, and gets HOT, so my emergency plan is all chiller related. I do avoid obligate cold water species just so my stress is a bit lower when that happens.
Stay safe, everyone!
