You guys down there in Oz do have an interesting conundrum. On the one hand the importation ban means you have to re-invent the wheel to see the Koi you want. On the other hand, you GET to re-invent the wheel... Nice to see you making the very best of your circumstance.
Knowing the type of parent stock could help pin down the nature of the Ki. If it comes from a parent with the slow developing Ki that maintains a softness into maturity it would make it very unique and possibly beautiful in years to come. That characteristic is unfortunately rare in the Ki Utsuri I've been exposed to. The few Ki Utsuri/Bekko we have are rather on the hard, brassy side
, but they're just pond mutts anyway.
I hope yours hangs on a while longer. If the Ki does develop the pattern looks like it could be interesting.
