Just so people know here...Efflo...commmon (meaningless) name. Refers to Acropora efflorescens. There are many similar Acropora forms, so actually identifying can be pretty hard/impossible. Plenty of people can grow this coral to a large size (there was once a bunch of large pieces donated by a BRS member to the auction), so I've never understood why the price of frags was so inflated. This is one coral I never put into my system, no particular reason, just didn't have that much appeal to me.
