NANFA-- cold tolerance of southern fish

Since it's so hot, I'm thinking of winter, and remembering how very
uncomfortable I am when it is cold.

As I look at the fish I have collected from more southerly locations this
year, I wonder what I need to do with them this winter.

Does anyone know how cold tolerant the following species are:

leptolucania ommata
bluefin killie
american flag fish
fundulus seminolis
fundulus cingulatus
fundulus chrysotus
Heterandria formosa
sailfin mollie

I keep the fish in a mostly unheated garage. Unheated tanks get down to
around 50 degrees. That's really nice for my local fish, but I am not sure
about the southerners I am keeping. I'd rather not heat the tanks if I can
avoid it, but I also would rather have the fish survive the winter in good
