Hello, I am starting a cold water aquarium with a volume of around 1000 l. I would like to have burbots here. But there is a problem with the temperature. I read on the Internet that they do not thrive in water with a temperature higher than 15 degrees Celsius. I would like to ask if anyone has experience with this? Unfortunately, I cannot keep the temperature below 20 degrees Celsius in this aquarium, the temperature will probably be around 22 C. If it is not possible to keep these fish at such a high temperature, I will put them in an outdoor pond.
