I am with KoiNut that the breeder would never let go of anything that is worth keeping for a few more years. However, some breaders let go the tategoi as a tosai such as Hoshino,Maruju...I have one Kohaku which I believe "tategoi". I will try to grow her in my pond and see what develops. As KoiNut mentioned, the koi wouldn't very good for show purposes now, but I will try to show her anyway
