From the looks and sounds of it, its highly likely a

Taxo in corals is challenging at best, esp with
soft corals because of the lack of a permenent skeleton that exhibits certain standard feature for type. Soft corals can vary in color and appearence dramaticaly among same species.
There are very few people actively studying coral taxo and they dont agree among themselves. In most cases if you can ID it to Genus you are doing good
