great question! I learned something new today. I didn't realize that butterfly koi were not a "pure breed". You will find I'm illiterate in koi terms/vocabulary, I speak fluent canine though. So please forgive me my errors and teach me, as I want to learn, when I make errors.
I bought 3 butterfly koi mainly due to the joy of the long flowing fins of my shubunkins. I know my future will be to be creative in how i build my next pond to give these fish there rightfully sized home (found out they can get as long as 3 feet, and I must be doing something right, as they are growing quite quickly). I have a small backyard and I'm quite limited to the beauty/ breath taking homes I have glimpsed at so far. It makes my ponds look like gold fish bowls.
But back to the topic at heart, I picked my koi as I did my shubis by what attracted me. Going thru several links in attempts to learn what I had, I became confused.
I did upload some pictures (couldn't get the videos from underwater to work, much less the videos from above) and have no idea if I did that correctly. Currently tapping this out on a handed down iPad, so another learning curve, that when frustrated, I head towards my laptop, so cannot quickly upload pictures now. Can do so later, let's see if a description will help for now.
1 of my 3 is all black on top and has some orange on the belly, the fins, close to the body appear to be a cream color. I believe it's a Karasu. The other 2, I believe are Matsubis. 1 has a very orange head with black along the top of its body (I have tried to get a closer look, as to it's metallic features, or lack thereof, and if the black is more solid or spiney). 1 has a blue/dark gray body, and it's head went from a near solid black, to a collar of black with a head "blotching" orange and cream.
Could anyone direct me better than Internet surfing? I became confused in the aki, hi, asagi, orenji (orange,I finally understood orenji means orange), and other oriental terms. My orange koi, was purchased as a Malaysian butterfly (I purchased 3, lost 2, and was given 2 in replacement). My next two were next to the Malasians, but these were just tagged butterfly. He wanted me to receive 2 of similar sized as mine if not larger, but that is another question, what, if any is the difference?
