sub species naming is tricky and often done incorrectly. in the end you may get 3 different opinions and none be right, the question becomes why is it a big deal to you the sub species. Its from australia, which i have imported from, so you either have a coral that is grown in 10 feet or less water or deep water. based one the structure i would say top water species so high light, high flow and watch it grow with stable params. good luck.
