I thought I bought a chalice, but researching further, I may have a montipora, or may be a Echinopora or Cyphastrea.... Any thoughts, as I would like to know exactly what I have.
I actually looked at that photo from Divers Den before I made my original post.
Whatever "derped" means, I think it's me who did the derping. I could have sworn I saw the coral had extended polyps like the M. venosa or the M. monasteriata. Maybe I'm getting senile or it's been a long weekend.
Being sold to you as a chalice is correct. The Echinopora lamellose is the Original Blue Chalice.
