Encrusting coral question

[rusty]

I have two encrusting corals in my tank that I have been trying to get identified. I have been told the they are porites and I have been told that they are encrusting montipora. You tell me :biggrin:

this one is darker and the polyps have a little green centre to them. the polyps on this one also extend out farther
