Acropora ID please

[ViktorVaughn]

Any help with an ID would be great! My spreadsheet listing all my corals and their purchase dates and the accompanying picture progression folders is making me cross eyed trying to find anything (Thin Purple Acropora, Thick Green Acropora, Thin Green Acropora, etc.).

Anyone have any ideas? Even a few guesses might help to narrow it down. Not sure if it is too small for ID, if so I can try again in a few months.

Maybe A. parilis if it is a stag.
