I'll take all 3.... depending on the price.

Rather large for tosai, so I'm guessing they have been grown fast in warm water. Even 'jumbo tosai' out of Japan do not usually get so long until Spring, so I think these must be raised in a warm climate outside Japan. Chinese-bred? If so, I am impressed with the progress of Chinese breeding efforts. Very nice body structures for tosai. Pigment can not be evaluated well in photos, but no horrible flaws for tosai. I rather like the odd face pattern on the second Kohaku. The Sanke is a curious fish. The Sumi seems to be progressing at an earlier age than I would think, perhaps due to being raised in warm, mineral-rich water??
I'd like to know more about them and their parentage.
