My sun coral took a few days of convincing (minor). I would just shoot some PE Mysis it's way with a turkey baster and after a couple tries, it finally started eating. You can train them to know what time of day they'll be fed, mine know if the actinics are on, they're about to get fed. If they're puffy but no polyp extension, you should be able to entice them to eat.
