Also for all those that are interested in an Centropyge aurantius, just to let you know, they are not really 100% "reef safe".
Mshur (Mike) had to tear apart his 140g reef a year or two ago to get his Golden out and my Golden is an SPS nipper. I don't believe that he does enough damage to kill the Acros but never the less, I've seen fellow hobbiest rip apart their reefs to oust the offender for less infractions. I can also tell you that this fish probably would not do well in an LPS enviroment. The Golden that I have decimated a Favites and picked on an open brain and last, it'll nip on clam mantles every so often also.
So no "mixed" reef for this fish and if your SPS dominated, you need to have a large enough tank and diversity so that it doesn't kill any one or two acros.
