I purchased a "named" Zoa frag from an online dealer a couple of weeks ago. There are 2 adult polyps and 1 baby. One of the adult polyps has never fully opened and now the stem appears to be turning dark. The adjoining adult polyp looks fine and has a nice "clean" stem. Should I go ahead and frag off the troubled looking polyp? I will have to cut / seperate it from the adjoining good polyp. Advice?
