I thought suncorals...

Were nighttime creatures, mine opens up for every feeding time. I feed my reef tank 3 times a day, I alternate, one feeding is flakes and algae the next feeding is Lifeline carnivore/herbivore with more algae, the last feeding is reef bugs, cyclops, brine shrimp and live shrimp(for comet). The sea cucumber has a banquet during the last feeding.
But my suncoral opens up during every feeding and remains open all night. I don't feed it individually with a baster like I was told to do.

That's good !it sounds like he is in a happy place in the tank and the foods that you have chosen are all good ones

I get the reef bugs from your store.

It might be smart to start feeding it with a baster. It is either happy or very hungry.
