well are you going for an adult queen and what size about i would add the gray angel in the first 2 weeks and then in the second 2 weeks i would go for they queen but add you angels as your last fish as they become very terirtorial to new adisons
like add your tangs,clowns,triggers,dwarf angels,damsels,butterflys,basslets,wrasses first
then add the aggresive ones last
