Bubble ID

[Eduardo]

Could you please help me to ID this bubble coral? I think it is not fully opened however it has already a week on my tank.

Thanks

The ID that I am looking for this bubble is the species, I saw a lot of photos over internet and I think the bubbles of this coral are not as big as they should, and I would like to be sure that this is normal or I should take care of it

After review the info given by cloak (thanks), I think I have a Physogyra lichtensteini (Peral Coral) and the small bubbles are ok if I am right and this is a Pearl Coral.
