Koi ID

Can anyone ID this Koi for me? I'm not sure what variation(s) this fish could be. I got this fish when it was only about 2 inches. I put it in the pond in May this year when it was 3.5" and it is now about 5.5 - 6". His coloring has changed a little as he has grown.

Not the best picture in the world, but it is hard to get him to sit still long enough.

Yes, the red is still there. It has become a deeper red just within the last 2 months. The black part has spaced out more which I assume is to be expected as he grows.

He is growing like a weed. He has grown probably 3 inches in 1 1/2 months. In that picture he is probably around 6 1/2" and that picture was just taken last weekend.
