Suncorals being "black corals" (non-photosynthetic) need feedings almost daily (or more)...I think that's why Kris is asking.
I feed mine sometime a couple times a day at different times if the polyps are out. Here's a pic I took last night for example when I saw this post
(Side note: Where's Waldo? Can you find the eye looking at me)
So in the photo obviously most of the polyps are out but I had to nurse/train the corals to come out more frequently. If they aren't trained before hand you have to coax them slowly to come out by "feeding" them a couple times during the day. I say "feeding" cause it's really just spraying some frozen food broth over them in hopes it will entice them to start having their polyps it more with time.
Hopefully that helps, I know I've had various "black corals" over the years and if this wasn't done regularly they slowly recede and die off.
