Very cool growth form, not familiar with it off the top of my head. Name it whatever you want, but why are we naming a pic of a coral you found online? I would like to see a normal shot of it under good lights with no gel filter before I take a shot at naming it.
Looks like it's tabling and a nice thing branching type coral. But the branches could be looking more upward than it looks like. I wouldn't call it a stag though. I think of thick long branching, with coralites that form randomly and spaced out when I think staghorns.
