I recently received this coral from a local reefer and was doing well in my tank for a few days. It started to retract and shed which i believe is due to the parameter changes and has stayed that way for about a week or two now. I started to notice some discoloration towards the foot. Is this a process of shedding or is the coral on it's way out? Anything i can do to help it? I recently did testing and did a water change after noticing some nitrates and ammonia due to overfeeding and stuff. I know these corals can stay in this shedded state for a while, but nothing was mentioned of that discolored foot.
