I am probably wrong here because i am going up against all the big names : ) but #2 looks a lot like my red sea xenia. Do the ends of it kinda pulse open and close?
When touching, do the polyps fully retract or just shrivel and clump together?
The picture shown looks like each polyp has its own "trunk" which would point towards clauvaria.
They just shrivel together.
Thanks for the correction all. good stuff to know.
