Roughly, acropora.

It would be so much easier if you had close ups of the colonies in question. That would likely get more responses.

Acropora have sticklike structure---what distinguishes one type from another is the growth pattern, whether the polyps chain up the stem, or twist, or branch, etc. Need closeups of full-blown colony to make any judgement.
