Cirrhitichthys aureus is an interesting species. AFAIK, it is the only Cirrhitid that is a simultaneous true hermaphrodite (both male and female all at once). They feed on smaller fish, as well as the typical crustacean fare--relatively hardy like other hawkfish as well. Oh, and Project Reef's Cirrhitid is Paracirrhites xanthus--a smaller and more behaved species than the other one.
