Depends on your angels and order of introduction as well as size of course. A queen and emperor are much less likely to make it than a regal and majestic (navarchus). Just figure out what you like and research them. Typically you only want one holocanthus/pomacanthus and have them be the last in the tank. For example I would choose either a blue face, emperor or queen but not more than one of those. You can also add a dwarf (centropyge) but multiples can also be tough. I have two potters in with a scribbled and goldflake right now. Added a multicolor with the scribbled and the dominant potters beat the snot out of him-had to pull him and let him recover. Going to take the potters out and leave him in sump for a bit as a time out and then reintroduce so he wont have the set territory of the whole tank. Majestic and baby annularis in qt
