Good morning, I am currently at work and do not have parameters to post. What I will say is my fish, soft corals are doing great, I had a montipora that did not thrive in my tank. I noticed my serpent star looked to be really struggling and after a call to LFS they said if the central disk is damaged it’s unlikely for them to recover.it was unusual for my serpent star to be visible at all with the lights on and that is how I discovered it like this. Does this look like something my Pistol Shrimp or my blue legged hermit crabs would do? Or does it look strictly parameter related. If it’s unable to be answered without parameters or against rules I understand.
