Bonnie, Butterfly Koi are bred differently and as a result they are cheaper to purchase. They are beautiful colors. You can identify them by their longer pectoral fins (next to the head). As they continue to grow, those pectoral fins get longer and stronger, and they can dart across the pond at lightning speed, like little rats. One of them died, and there is only one Butterfly Koi left. I purchase the koi locally, and I won't buy butterflies again.
If I put my hand in the pond, they come over to nibble. Do not pet them as it disturbs the protective layer on their scales.
New fish are placed in the pond, bag and all. When we're comfortable that the water in the bag is the same temperature as the pond (usually a couple of hours), we open the bag and release them. A large koi in a plastic bag can bag around the pond like crazy.
By the way, the fish all come to me, except when I'm wearing a black top. I think they need glasses.
