I've had koi in a 1000gl pond for 6 plus years. I've only heard people rant about keeping koi "pure". I've been doing research because I just noticed that some of my 3 year old "koi" that are 12-15" long DON'T have whiskers! I don't see as well as I used to but the whiskers should be obvious if they are koi! I never buy a "koi" unless it has the whiskers but now I've found information on hybrids! Too cool! Can someone tell me what the appeal is for breeding the two together besides the excitement of seeing what you get. Thanks
