| Secondary Hi
Several of our 2 year old koi are developing this problem.
Has anyone any advice on how to select future koi with less chance of developing it?
Will it go away?
The koi are from Momotara, Sakai and Muryama. 3 are Sanke and the last is a Kohaku.
I have never had this problem before so I am wondering wether food has any part to play, or was last year just a bad year.
Thanks
