Quick emperor color change update... it's like that mouth turned white overnight! He's also starting to get yellow on the top of his head and near his eyes.
Also, picked up a piece of the tubinaria heronensis coral as well from Aquadome after OU12004 posted that he picked it up. Can't believe I didn't make the connection that it was that coral when I first saw it at C4.
I've coveted this thing ever since I saw this Reefbuilder article on it:
