Hello, I have had this coral since June and it looked really good until September which it closed up and never really opened its polyps as it had again. I have multiple other leather corals in this tank (which is a Fluval 13.5) including a decent-sized neon green leather that has never looked better, yet this one looks like it is going to die. Should I buy an iodine dip for it as its skin doesn't look right to me?




. Mine likes medium light and medium flow, it's about 14 inches from the surface.
