I have Redears. Central Ohio is far enough South for them to live most of the time. I lost several big ones (up to 10 1/2'" long) at the tail end of last Winter in three nasty supercooling events - 2 below freezing periods with high winds (preventing a relatively insulating layer of ice from forming, and prompting maximum heat loss from the pond) lasting over a day apiece, and a 15 inch snowfall on open water that turned the pond into a giant slurpee drink.
PS are really pretty and I would not mind having them as well.
