Peacock Grouper

Cephalopholis argus

Peacock groupers are attractive fish that often are shades of peacock blue. This fish was introduced into Hawaiian waters from French Polynesia in the 1950s as a prospective new food fish. Unfortunately they were found to contain ciguatera toxin and now are abundant on Hawaiian reefs but not generally eaten by humans. Often a peacock grouper can be seen hunting with an eel, each trying to force prey around or through a coral head while the other eats it.
