Mutt or what? Koi ID help required
A little background. I have a small 1000 gallon pond in my backyard. A couple years ago there was a knock on my door. It was a neighbour from across the street. She asked me if I was the guy with the pond and I told her I was. She said that her and her husband rescue fish from people who no longer want them. She said they got 6 small koi (3"-4") and they were tearing up their 100 gallon tank. She asked if I would take them off of their hands. After losing my only koi a couple months earlier this was a no brainer. I wintered them in the house and the following spring out to the pond they went. This is their third summer out there. They have done really good and are growing like weeds (5 of them around 12" and one runt) I have done a bit of research with links I have found in this forum and think I have identified a couple but I am not 100% certain. I would appreciate any help. It doesnt matter to me if they are mutts or not, it would just be nice to put names to some if possible.
I believe this one to be a "Kigoi"
I think this one is a "Karasugoi" (all black with an orange belly)
I am thinking "Bekko" for this guy
The following 3 I am a little lost with
This is the runt
And this one
And finally this guy (had a hard time getting a good picture)
