Steve are you looking for that specific species or any blue tip green stag. The Loisetteae aren't as common as a microphthalma or Formosa. They look very similar except the branches are thicker than the Loisetteae which tend to be very thin. I had a colony years ago in all blue. That large blue tip in my tank is the Microthphalma. I read that article too beautiful coral.....
Pretty stag, but I don't think its a Loisettae. The branches are thinner and mostly straight. Also the corallites are shorter on the branches while on your stag they are taller off the branch.
