as i was saying there is no indication of sumi on mine.....yet
as some of the other's have stated and are unfortunately correct, the beni
is on the way out.
You'll be surprised what it looks like when red is gone. there is the sumi and it is kinda shaded looking and all the koi kichi's that come to your pond will squint and scratch their heads trying to figure out what color variety of koi that is and what it will look like when it finishes. I saw one this weekend and they thought they had me on what had happened.
I hope you'll not feel uncomfortable about this koi as if maybe you or the breeder did something wrong. Look at it as part of the investment in your education. Many serious show types will tell you this event, which happens with the best bloodlines and pond conditions is why they buy less koi and invest in a 2 year olds. Some of the koi kichi's I run with only consider 3 year olds for that reason.
But I'll still put on my seminars on Tosai selection, because there is value in learning from both failures and sucesses. Like the old expression says..."the harder you work at something the luckier you get ".....
My advice at this stage is for you to not push growth on this fish, allow it to experience winter and if at all possible to control the PH, pls try and keep this koi in the low 7's......(7.2-7.4)
