Woohoo, Pecan, have fun watching the spawning dance! Jen, they will get tamer the longer you have them. I tamed my babies fast because they were in the kiddie pool all winter, and I hand fed them eventually. And, they were all hand fed from the previous buyers, so that helped as well. Some people never feed their fish, as they have "natural" ponds, and probably much clearer than mine! LOL But, I like my koi to be friendly. And, once you have a friendly one (and, believe it or not, some colors are more apt to be friendly than others - Chagoi I think is brownish or grayish, is supposed to be very friendly, and white or platinum tends to be more standoffish ... so if you get a chagoi, it will help your others learn to be friendly... or so they say), the others will follow suit, not wanting to be left behind. My white is a matsuba (dark scales on dorsal topline) and is NOT friendly at all. In fact, unless the water is clear, I typically do not spot it very often, as it stays lower in the water. My 2 Chagoi koi, though, are first to the dinner table. LOL BUT, my koi I got last year from RSFish were hand fed, so they came very tame and friendly.
Just try feeding at the same place every day (when weather and pond temps permit, that is) and stand very still at first, and they will learn. Probably weather has not allowed you to feed so they are not interested in you yet. They will learn!
