Your going to love that fish! There are some great details to that fish that you'll really like, The white fins are going to really pop, On that sparkle from the back the flow of the fins is going to really stand out, It has a very strong body shape and great head form and the coloration is a great pick for that type of fish and those thick double barbels are nice and long! I really like that fish, If I had to make a quess I would say it's probably a male. i have a far darker 22" Chagoi Butterfly, it is not gin rin but your right they are eager eaters, once they are at your hands feeding they want attention, they are a calming fish, you'll notice once they all settle in that everyone will re-act more to what that fish does. If he's hiding, they'll all be hiding, If he's friendly they all get friendly. Weird how it works but that one kind of fish is really a nice addition. How large is suppose to be? Looks to be between 8"-12' from the pic but no way to really tell. How large is it in comparison to the rest of the herd? If he's one of the largest in the group he'll even become more of a leader fish. I've heard that by adding a Chagoi, Kigoi (Yellow version) or Ochiba shigure koi to your pond that you'll actually reduce the risk of fish jumping out.
If you got it from online I really suggest quaranteening it. i've made the mistake and not done it and it cost me dearly. Out of curiosity if I may ask, who are you getting it from/ is it a ebay fish/ LOL looks like a NDK koi and if so you'll be a happy customer!
