Acropora xxxx?

[bhsgk]

I am just starting to get into sps and I am trying to learn as much as possible, but that is kind of hard when I don't know which species I currently have. Any help is greatly appreciated. Thanks

The lighter colored one could be carduus if it grows like a bottle brush. http://coral.aims.gov.au/speciesPages/species_metadata/0014/view#

Maybe kimbeensis if it grows like a stag. http://coral.aims.gov.au/speciesPages/species_metadata/0444/view#
