I wish I had that color! Green tends to be really common among trachys, though I'm not willing to spend a fortune on a massive red one. Do you have any photos of it at night? Definitely has a unique polyp shape among trachys, though I don't know if it can be anything else. Maybe @encrustingacro could verify if im correct? The shape sort of looks like a lobo rowleyensis but the skeleton isn't one of that, too flat to be an acantho, though my bet is on trachy.
