Many say that to get a true ID, would have to dessected under microsacope. I am sure others would give good guesses, but it might be best to just keep searching the net and making comparisons to what you have. You will get a better guess once you see how it grows, if it is a tabling acro, or branching acro, etc.. best of luck, and enjoy. I do not know what half of the coral frags I have are, I have a good guess, but not exacty sure. But it is fun seeing how they respond to light and flow, find out what works best for that particular speciman, and watch it grow and color up.
