Thanks for the site there TDevil... that'll help a bunch in the future.
Thanks for the input wooddood.
Thanks for the ID there Cosmic... looks like we have a winner.
Hiya Luis. Yes, the polyps are already extending... my wife said they were out pretty full earlier this morning, but right now you just see little bumpy rings all over it.
I've been reading up on
Acropora efflorescens and mine pretty much fits that description, with most corallite growth on top, though there still are polyps showing underneath (though no color or bumps... it's flat).
I'll look into Solytariensis and see if the description fits better.
It was quite the score... when I saw it I just had to have it, and it fit perfectly in the first spot I picked out in the tank... looks like it was meant to be.
I'll see if I can get a closer shot in the morning... only the actinics are on right now....
actually, I have a shot of it in the bag when I was acclimating it... maybe that might help.
Thanks again for helping me ID this thing everybody.
