I recently got a koi for my birthday and i plan on building an outdoor above ground pond out of of lumber 4ft wide 8ft long and 4ft deep. is that enough for one koi. ive been told i need 1000+ gallons for my one fish. the fish came from a local walmart super center, its healthy and in good condition. right now it is about 3inches long.
