Help with coral ID please

[Candy2327]

Hello hoping somebody can help me identify this Coral. It was a hitchhiker on another piece that I bought a while back and it's been slowly growing. It's very pretty would like to know exactly what it is. I thought it was some type of montipora but today I saw a pretty long feeder tentacle. So now I'm not sure thanks for the help in advance I appreciate it.

Looks like some kind of sps encrusting coral. Maybe a pavona? Someone else will chime in here Im sure.

Hard to say, pavona or merulina coral.
