Good day I was wondering if anyone can tell me what type of coral this is a friend gave me this but he didn't know what it was either. It looks like a type of Montipora but it won't colour up it didn't colour up in his tank either, every so often I can see green pylops popping out but that's it. It does encrusts rather quickly there was a dead spot a week ago and now it's almost all gone. I can't move it because it's glued really good to that rock that's the rock he gave it to me on lol.
