My tank is naturally about 14-15C (about 57F) but it does often drop a bit colder over night. I thought this was a little cold so I bought an aquarium heater only to find the lowest temperature it will do is 20C. Is it better to leave the tank without the heater (slightly colder than recommended) or add the heater and keep it at a constant 20C? At the current temp my to little ones are a bit dormant to say the least!
