Judy, I have unfortunately gotten a cranky boy reputation as I always seem to be raining on someone's parade on these boards. I'm not that negative a person- honest!!

But we all have to admit that some times these boards get so syrupy nice that they are downright cruel to the person asking " do these spandex pants make me look fat?" I mean they do want to know right? :0)
So in that spirit----
There are no koi with any real future in these pictures. It looks like you have spend a lot of time and money getting this grow out up and running and you deserve to get better results. Maybe it is the breeders you are using? Or maybe the general quality of your stock? Or maybe this is just the rest of flock spawning? Whatever the case, I would not waste time growing these fish any further and it is probably best to find homes for them so you can concentrate on a fresh start.
Best of luck, JR
