I live in South Louisiana and have the same weather as yall in Florida. I can tell you that Crappie {Soc a liat} as we call them are a very bad choice. They do NOT pellet train very easy, and dont grow fast at all. Bluegill will pellet train a little eaisier, but again dont grow fast. Tilapia are the way to go here. A few tips to survive the winter are to wrap your tank with the roll insulation. Cover your tank with the hard foam insulation. And put a aquarium heater or two in there. Works fine for me!!
