It seems like most of the resorts in Hawaii have koi ponds. An Asian influence I suppose, but they fit the tropical setting. It's relaxing to sit and watch them swim back and forth, and of course when they see you, they come expecting to be fed. The Red Koi Collection Gallery on Kauai has a great widget on their website. Hover your cursor over the koi and they follow it, click to feed them.
I've taken many pictures of koi through the years and finally got around to painting some.
