I got a full polyp of this from the OP" benihana " in a trade about 16 months ago. If you could see this in person I seriously doubt it's any lobo species, but I'm no expert.
The polyp size at max is 1 1/2 -2" and circular. It has since developed two maybe 3 mouths & is slowly spitting into 2 smaller circular pieces.
The only other coral it matches to me in size, shape, & looks is Scolymia australis.
