I like this fish but having said this I thought that with Showa it was not so important to have a good kohaku pattern of Hi but more the overall pattern and balance of Hi and Sumi together. I am still a novice at choosing koi and for this reason have not yet purchased a really expensive one - so am probably getting it all wrong. Strictly speaking this koi does not have a clean odome as there is Hi at the very end of the tail tube but that should not be a detriment in a showa. I think that as this fish grows the Hi will tend to fade in many places and the Sumi will come up in others, please correct me if I am wrong.
