take it easy, buddy.
Honestly, I have no idea how to keep one. My guess would be to get a pond as big as you can, but no smaller than 8x12 and 4-5 foot deep. Keep it shaded with steep banks to prevent predation. A mesh cover would be good, too. A heater or aerator will prevent freezing but will be expensive to run long-term. Make a filter out of a stock tank, media, and pump and find a source of live food to feed the guy.
Lots of work, but it would be cool in the end. Go to some koi sites to get ideas how to build a pond and filter.
