So I have a small, raised container pond that is about 60 gallons (or more) with a few baby fantails. I live in south Louisiana and we have pretty mild winters for the most part. It rarely gets below 32 degrees and isn't really cold long enough to freeze large amounts of water. But the weather is very inconsistent and can dip to 40 one night and get to 70 the next. I would love to invest in a heater to keep the water a consistent temperature and my fish happy. I already have a water fountain and an underwater power filter so it is well aerated. I know the water won't freeze this winter but I want to make sure my fish won't get too stressed with the varied temperatures. Any advice? I know aquarium heaters aren't advised to use outside but could they work since I don't have a harsh winter? I plan on insulating it as best as possible too.
