Two things
Fish at that size and price point have had their photos taken several times. I'd ask to see some of those pics.
Second that "kohaku" is so bad that I had to convince myself that the showas are not of the same lineage. I expect that "beni" to shred. First the head pattern is scaring me the way the beni stops where the skin meets the scales. And then the leading edge of the middle step is a complete and total mess. Dealers usually group fish together based on pattern or quality.... if those showa are the same "quality" as that kohaku...really?
Third, the pattern on that "kohaku" is about as attractive as a piece of gum on the bottom of my flip-flop.
The dark smudge is actually redeeming quality.... In a year, whoever buys that koi will scowl at it. In 4 years it'll be a different fish all together. But who knows what? An entertainingly-patterned shiro utsuri?
The same can be said for those SHowa. They are going to change...just how?
