I have a 1000 gallon + pond at my disposal. Could I keep my Florida Gar in there all year round? I would have a pond heater on of course. I live in Southern PA. I got the idea from my neighbor who keeps his gold fish pond covered in the winter with what looks like a short transparent, plastic tarp greenhouse. All he has on it is a de-icer and the water stays in the high 40's with the air temp inside around the 50's. I guess if I had to I could bring him inside in the winter. What do you guys think?
