Welcome to the site Bart... Sun corals are non photosynthetic, which means they don't like light, do try placing them in a shaded area where they don't get too much light. And since they don't rely on the lights for food, you'll need to manually feed each head with some type of meaty food, like mysis shrimp for example. Good luck with it, it's truly a beautiful coral.

U can also try to feed the tank when the lights are off and see if it will come out to eat

+1. They mostly just open up during the dark hours and need to be manually fed multiple times a week or they die off. You can train it to open up when lights are on, but that takes time and you will have to try to feed it when lights are on to train it to extend polyps during daytime.

I think you'll also need to consider if you have fish, if so then they'll most likely go after the food you try to feed the corals. You might want to start off using the two liter bottle method. That worked for us.
