Coral ID?

[dvasko189]

Could anyone help me ID this coral? It seems to be losing some of its skeleton on the bottom right corner. Looking to do some more research before things get worse but don't know the name. Thanks

With that thick of a skeleton I am thinking acanthastrea rotundoflora or acanthastrea echinata. Leaning toward the echinata as it is more common.
