Hello, I am setting up a 29 gallon tank with sailfin mollies caught in the river 6 blocks away in SW Florida. We don't keep our house very cold at all. They are native, do I need a heater. I have had one 3 inch male in a 5 gallon about 10 days with no heater, he is doing fine (other than being cramped in a small tank)
My 29 gallons arrives tomorrow.
