Rabbitfish and foxfaces have great personality. they are sort of like slow, mellow tangs, IMO. I don't have the species you are interested in, but I do have a Siganus corallinus (blue spotted rabbitfish) that I've had for years, since it was 2". It's about 8" now. Great temperament, hangs out with my emperor angel, never stops eating, goes after algae. I don't have corals in my tank, so can't address that issue.
Research the size, as some rabbifish get very large. They are hardy and grow fast, so make sure you get one that is the right size for your tank.
