Generally speaking larger angels won't pester smaller centropyges, although you might have some pushiness from time to time. A 100 gallon tank is nice, but many of the "large"
angels will outgrow it in time. I agree about the Rock Beauty. not an ideal specimen and many perish even after seeming to do well for periods of time. The lemonpeel is also a dwarf angel although one of the larger ones. Personally, I'd attempt to add two centropyges of different species rather than a large species of angel. Add them at the same time. I have a multicolor angel in my 120 and he rules the tank. The smaller angels are evetry bit as colorful and personable and they have some major attitude.
