Hello everyone... I live in Jersey, and in the winter, it gets COLD here. Theres 6" of snow on the ground as I speak. Now, It has been my dream for a while to have a monster pond, and this spring I plan on building one. The plan was for koi and goldfish. But then I started thinking "they're boring". I was thinking about how AWESOME it would be to have a pond with something like midas/p-bass/oscars or even like a ray or arowana. I was wondering if there is some way to keep a pond tropical temps all year round? It would not be huge, probably something like 8' long oval, 3-4 feet deep. Is there some way, like insulation, or industrial heaters, etc. that could make it work? Maybe like a hot tub heater? Does anyone else have one in a "cold" area? If not I may be a pioneer 
I would really like for this to work, and i think with something like a hot tub heater, it sounds possible.
