That is a very nice looking fish of course I can just say that on astetics since I am not a pro, but a very attractive fish indeed. My longest lasting koi in my little mud hole
has been there for almost 9 months (I know not long at all) is somewhat like yours only I think its a he since he has a more slender body and is only 10 - 12 inches long. We all pick "our fish: when we get them and that one is my 3 year old daughter's choice fish while he is no where near the quality of yours we would all be very sad to lose that one.
You said you have other koi that have won awards? That is awesome it just tells of the care and love you give to all your fish friends.
