I assume you are using european time stamp as these pix would be from last spring if you were american.
15-20cm at 1 month would be very good growth, but even at that it is difficult to tell much at such a young age. Culling at that stage revolves around physical deformities rather than color and pattern. Yellow appearing in virtually all fry is to be expected in the early stages of growth. Some will remain so, others will either turn white, orange, or red over time. It is definitely a waiting game.

I have been casually breeding for the last three years and this year I decided to have a go with two of my nicer koi the female was a modern showa and the male was a kohaku. I realize that it is more desirable to breed black based fish together but I have heard of some people having success with Showa/Kohaku and seeing that the only black male fish I had were pond muts so I stuck with the Kohaku. Anyway it's been a month and the fry have been growing really well, their about 15-20mm. They are mostly yellow and black. Basically I was just after your expert opinions on how they look and whether they are coming along as should be expected colour wise. I know it's pretty early to tell anything much but I'm sure that those of you who having been breeding for some time might be able to give me some insight. Like is it normal for them all to have some yellow on them? I look forward to hearing from you, thanks in advance, Jim
