ID please. Montipora, Porite or Seriatopora

[OrionN]

Here is the picture. How can you tell these three genus apart? It is an encrusting fast grower but will send stub projection up from a flat surface. TIA

pink Pocolipora

I don think it is a Pocilipora. The coral you see in the picture is 3 inches in height. The stubby projection are minimal. It is an encrusting coral. It is bright pink under high light.

 

[Frankenpora]

In my oppinion this is either a Poccilopora as stated above, or
It could be a Stylophora - This would be my guesse -
It is not a monti, or birds nest IMO, I suppose it could be porites, but I doubt it. I think those nubs will develope further. Both Poc. and Stylo. will encrust before they grow out.
