Im pretty sure that's not Vivid Rainbow Delight Matt. The rainbow delight doesn't have green polyps...should be dark red/pink polyp and the body doesn't have that much green either. It also doesn't look like Cali tort either....at least my Cali tort has blue polyps.
Nice pick up! That's what I love about this hobby...picking up some "brown" corals for nothing or cheap then it turns into a gem
