It's really hard to say by what is shown. Potentially any Acro can be neon green, so color is a poor reference.
I don't think it is Acropora caroliniana because the tips are not pointed in the same way. Plus there are large radial corallites all over yours. A. caroliniana radial corallites are small. Corals of the World Factsheet and images - Acropora caroliniana
