I currently have a pair of pink skunks in my 58, they share the tank with a Potter's angel and a golden algae blenny. For the most part they all get along, though the pinks will chase the other two from time to time.
A couple of years ago I had a royal in that tank. Wasn't too many issues but the royal would try to intimidate them from time to time. But, that all changed once the pinks started spawning -- they became the rulers of the tank after that.
Overall I don't see any issues, but what size is your tank?
