Thanks for your feedback, the one on the right is also Yamabuki Ogon, but yes I agreed with you. It is looked like Platinum Ogon to me too. I was told to choose lighter shade of yellow or creamy colored is a better b'cos as it will turn more yellow when its turn sansai. Is it true?
Beside, we also choose Ogon few of these criteria like clean and smooth head with a large head and large pectoral fins. Any advise?
