I don't know how often they are sold/seen in the hobby, but if you can get some japanese contacts and an import license (or import them through a transshipper) then you can import some from japan. I am not sure if there are any people in the USA that actually have those koi right now.
oh..lol
well i'll go ask some Koi breeders in Japan about the 人面魚.
i don't know if people released them but they were on the news a many years back..people were surprised to see a fish with a man face...
SEGA even made a game out of it.
Do you not understand that hybrids are not designated latin names under the binomial nomenclature system? I also fail to see how you are unable to use google. Here's a quick primer. 1- You go to www.google.com 2- You type in a 'keyterm' 3-You peruse through the links and skim the blurbs to find one that may fit what you need.
You probably also don't know that you need a permit to import fish.
