You ca get the sun polyps (Tubastrea) to come during the day if you feed them, take a small cup of tank water and brine or any other frozen food and with a turkey baster blow across the polyps after a while you can get thenm to open. Not sure if you know but they do not possess zooxanthellae so light is not an issue and med flow is what I have found they like. They are great looking corals but a little high maintenance IMO.
