Can someone help me to identify this coral species found in Maldives?

[totototoma]

I saw huge quantity of this coral with no other coral species on a sandy area (<1 meter deep) in Maldives. They are small and act as a nursery area for a lot of reef fish. Would like to know what kind of species is it? Thank you.

Looks like Porites to me.
