Don and Dick,
The day I posted the photos, I decided to finally get off my butt and upgrade the lighting over the indoor pond. I installed a 48 inch dual tube strip light and am using one "Sun light" 5000K tube and one "Sun light deluxe" 6500K tube. I also added a blue/purple bulb for the overhead light socket. Besides the health value and maintaining the colors, I think the lights make viewing much nicer as well.
Thanks also for the feedback on the three individual koi. Regarding the sanke, it is interesting that you mentioned matsunosuke... that sanke has an interesting "glistening" to the skin -- it isn't gin rin, but it has a sparkle to the shiroji that is different from the other two. I have read about matsunosuke skin, but my newbie eyes have not seen enough koi to be able to recognize it. I will have to ask Brady if there is Matsunosuke blood in that sanke.
- Wayne, will aim to do periodic updates.
