just bought my first sun coral and have a couple questions. I need to know if each polyp is it's own organism? When I feed do I need to make sure I feed very polyp or do they share nutrients? I've been feeding in the morning and in the evening and I've been trying to feed every polyp, but of course not every feeding does every polyp eat. Plus I would like to know if I place the rock next to my reef will it start to spread up the rock like star polyps?
