All the tag really tells you is it's a maricultured acro from bali, which was placed into a rack on 7-15-13. The rest are codes and/or identifiers for regulation purposes.
The species is not declared on the tag; Acro. sp. meaning Acropora sp. (species unknown).
It's either a prostrata or a millepora, but due to the pointy tips I'm going with prostrata: Acropora prostrata
