I feed Suncorals during the day, so that they're trained to come out during the day and I can enjoy them, but the rest of my corals get fed at night if I manually feed.
My fish get fed mid day lately, and I turn off all filtration and definitely admit to being a heavy feeder, so I'm sure the corals are getting food then as well. I must say that feeding at night is really cool, you get to see all the tentacles coming out and from what I have witnessed, you don't have to entire the corals as much, they're just ready for it.
