Denpends where the ponds at, and how big. If its outside and it gets cold in your area then he will have to either come inside for winter or you would need to heat it for him. Size is a big thing too.
If you mean a pond in the wild then no, but if you mean an idoor heated pond, or an outdoor heated pond, or a pond in a tropical climate than yes. Basically go for something 1000 gals plus if possible, and heat it to at least 78-85 f.
