First off this hollywood stunner chalice got blown off my frag rack and zapped one of my favorite coral purple polyp birds nest . It got it right at the base,some tissue loss in that spot,do I have to cut it past the dead part and re mount to a plug ir will it grow back.Second question I have a acro frag I just placed in between 2 rocks just to see where the coral was gonna be happy, and a little nub started to grow on the other rock.i dont want the coral there its too close to another one which I cant move. Can I pull it off the rock will it hurt the coral,the nub is like a teardrop size that grew onto the rock next to it. Thanks.
