Behavior and Habitat
Passive and slow, mandarinfish often use their large, fan-like pelvic fins to "walk" along ocean bottoms while browsing for the small crustaceans that comprise their diet. Although elusive and shy, observant divers are most likely to see mandarinfish in shallow protected lagoons and inshore reefs at depths of one to eighteen meters.
Appearance
The mandarinfish are so-called because their vibrant coloring evokes the silk robes of Imperial Chinese Mandarins of the 19th century. The geometric arrangement of bright colors has inspired some to call them "psychedelic fish." The males are larger than females and have long, pointed dorsal fins which they use in mating displays.
Unique Protection
One of few marine fish that lack scales, they are instead coated in a thick mucous with an unpleasant smell that likely repels predators and is believed to offer some resistance to many parasitic diseases.
Species in Danger
The species is threatened by over-harvesting for the marine trade, over fishing, destructive fishing methods and destruction of habitat.
