PEACOCK GROUPER           roi          Ao-nomehata

An invasive solitary species common on coral reefs at scuba depths.  Dark brown with many blue spots and a pattern of tan vertical bars which may be displayed at will.  Intentionally introduced to Hawai�i from Mo�orea in 1956 by State fisheries managers as a stock-enhancement experiment, the roi has proven to be a serious threat to native reef fish and culling measures have been implemented by local divers.  Since it feeds upon reef fish it often causes ciguatera poisoning and should not be eaten.  Attains 24 inches.  Indo-Pacific.
