On the whole "mutt" front...
My koi are all imported. Three from Japan, one from Israel.
The Japanese koi are from King Ed Pets in Vancouver. A very reputable fish store, and the owners travel to asia and pick out their large goldfish and their koi (along with various other fish) and bring them back for sale. I have a couple very nice orandas and a beautiful ranchu from there.
However, my koi from there don't seem to fit any of the proper pattern descriptions. Well, my red and white one does, but he's not viewed as ideal, because he's got some red in his tail, and the red spot on his head is on his nose.
My Israeli koi is a kin kabuto.
Anyway, I figured my Japanese koi were "mutts", as in somewhat generic and undesireable (I think they're beautiful). Does the fact that they were imported and that they're still small mean they're likely to develop colour into one of the recognized varieties? Or did King Ed just import a bunch of mediocre koi? If the latter, wouldn't it be cheaper for them to just buy wholesale domestically?
So confused...
