ID request for my coral

[cet98]

have had this coral for a couple years now and for the life of me can't remember the name of it....can any of you help me to correctly ID it please?
it has a metallic/neon green skin with new growth colored purple. polyps appear to match the skin color.

thank you in advance for looking

Looks like it could possible be an Acropora austera species. What does the colony look like?

Did yours come from ORA? The color is similar (potentially any species of Acropora can have those colors) but the corallites do not look alike at all. So if it really did come from that lineage then it is growing weird.

Do you have any pictures of your full colony?
