I think I'm going to respectfully disagree for a few reasons (mainly, the pictures don't give enough clues). My conclusion is that it is Goniopora stutchburyi. I *think* I am counting 24 tentacles...though it's hard to tell on a coral so small. From what I've read, the polyps on stutchburyi only extend about 1/8"...which is about what mine extend. I think Favia species polyps are just too large. This coral's polyps are only about 1/8" in diameter, if that.
Here's a goniopora stutchburyi:
http://www.reeffarmers.com/limitedgoniopora.htmhttp://reefkeeping.com/issues/2005-10/nftt/index.phpSays stutchburyi has polyps about 1-2 mm in diameter and polyps extend up to an inch long.
I think the best way to identify this is just to wait it out. The polyps may not be extending fully due to its recent acclimation, fragmenting, or it just might not have long polyps. Or...it might not be a gorgonia at all.
I plan to target feed this coral the "juice" from my DIY food...which consists of oysters, shrimp, 3 types of seaweed, clams, scallops, cyclopeeze, garlic, sugar, and cyclopeeze. It seems to react well to receiving food. I dose amino acid drops an hour before turning off the lights and then feed after the lights go off and the polyps come out.
