Seems like the polyps are definately a bit big and extended to be the sunset monti, color of the polyps is not the incredible green of my sunset, thought I have seen pics of "sunset montis" with that base color. Mine is definately the original LE and the base is orange, orange, orange. Very different form that one. That is a sweet little piece though. Chris at Reefer Madness loves a good ID challenge, check in wiht him on his vendor forum with the pic, maybe he might have an idea.
