I got a quick respond from Anthony Calfo The Author of Book Of Coral Propagation (good book)

Almarzouqi,
Good to hear from you, my friend!
The Xeniid in the picture, although not clear, is
familiar to me. It is believed to be a true Xenia
species and hails from Bali. It is a little less
common in aquariums. The nice thing about this species
is that it can grow quite large before it "branches"
(longitudinal fission).
I got a piece like this from a friend working at the Smithsonian but sold them all when I sold my store. After you have had a chance to propagate it, I would love to buy a piece off of you.
As far as propagation goes, it is more senistive
than most any other Xenia to cutting. Try instead at first to encourage rapid growth and fission through VERY bright lighting. Metal halides are in order after proper acclimation to the bright light of necessary.
Another interesting thing about this species is that
it is rather motile. You'll find it crwling and
creeping along the rocks at times (usually up towards higher light).
The first attempts with cutting should be
conservative attempts at imposed pedal laceration.
Do keep me posted about your success with it.
Best of luck to you.
Kind regards,
Anthony Calfo
