I know I'm a little late, but thought I'd contribute anyways. You pagoda looks alot like one of mine, it's really nice. They are one of my favorite corals, but I dont know much about them. Here are some photos, I only have close ups. <center>

</center> Mine only open under light. They can eat alot, when they get a bunch of mysis, the polyps will close for a while, and then sometimes the main body of mine swells up and little red dimples appear across the green background. Anyone know anything about that?
