Does anyone know how I can get my sun coral to put tentacles out during the day? I see pictures of other's sun corals with the lights on and their tentacles are out. I've heard that they can be "trained" to come out and eat earlier, but not sure how that works. I'm kinda tired of waiting til 1 or 2 AM for mine to come out so I can feed it. At 2A, it looks GREAT, big and happy, but all day with lights on, it's just the orange nubs.
