Is this Astreopora

Hi

I am trying to get a confirmed identification for this colony. Sorry for the poor pictures. I can try and take something better. My phone isn’t that good at tank shots.

Yap, only other possibility would be tubinaria, but the coral pictured has a bumpy costae, which tubinaria lacks.
Cyphastrea can sometimes be confused with asteropor, but its costae has defined grooves.
