My 1000 gal pond of 3 years is home to only 6 goldfish and several frogs. I
am thinking of adding koi, now that I have some ponding experience. I know
koi need more room than goldfish, and my concern is that they will outgrow
my small pond. I am thinking of adding just 2 4-6 in. koi to so that they
are similar in size to the goldfish. My largest gold is about 8 in. and
smallest is 5. Any advice?
