acan echinata or acan lord?

[RCRed]

Forgot to ask when I bought,
Is this coral I got acan echinata or acan lord (micromsussa)?
How do you tell the difference?

 

[Saltyreef]

Echinatas polyps are not as pronounced and seperated as lordhowensis. Lords have a more meaty polyp.
I would say this looks like acanthastrea echinata.

 

[thamnasteroid]

The coenosarc/mantle of Micromussa (lords) forms a lip above the theca giving the corallites a plocoid appearance. Acanthastrea (echinata) has concentric wrinkles/"warts" on its mantle/coenosarc.

Your coral is neither Acanthastrea nor Micromussa, but Dipsastraea rosaria.

I was thinking favia too but the skeletal structure on the mantle looks a little more raised than a favia.

Dipsastraea is (ex-)Favia
