Just noticed this split in my scoly. Anyone have any ideas if it’s going to be a problem or what I should do for it? Had the scoly well over a year. Only thing that’s changed (which I get is a big one for a scoly) is I changed the flow a bit (added a rfg like a week or two ago) but it hasn’t seemed bothered by it. I would hate to lose it-by far my nicest coral! Any help is appreciated
