Yep, I think you're right. It's got those "knobby calyces" typical of Eunicea sp.
The lighting in this tank is VHO, two Actinic White and one Aquasun (all newish) and one Actinic03 (very old). Next week I'm going to replace the Actinic03, and swap one (maybe two!) of the other tubes for Actinic03...then the colors will pop!
I love this piece...can you tell? LOL.
