My cardinal tetras did the same when I upped the ligths from 2 to 3 watt/g.
Eventually they got used to it and now swim everywhere, but it took
several months. I agree with you that they look better in shady
surroundings, but some sort of spotligth shinning on them makes for a much
better display. The best display of cardinals I ever saw is at the Boston 
Aquarium anaconda tank. It's very dark, except for some kind of MH spot 
that shines exactly on the spot where the cardinals stay. Maybe it is the 
opposite, they stay there because of the ligth ? Anyway, what you see from 
a distance is this shiny blue, swirling cloud against the dark. It's awesome.
