Lives wild in American Samoa, Australia, Bahrain, Cambodia, China, Christmas Island, Cocos (Keeling) Islands, Comoros, and 47 more countries.
Introduced to United States.
Live in shallow protected coastal waters to deep, somewhat silty habitats. Often with deep shipwrecks. Adults are found singly or in small groups and occasionally in large schools in some areas. Juveniles occur singly or in small groups among mangroves and inner sheltered lagoons while adults move out to open waters over sandy areas of deep lagoons, channels, and seaward reefs to a depth of at least 30 m. Feed on algae, invertebrates and small fishes.
Bacteria that attack the fins, mouth and skin, nearly always after poor water. When water changes are enough, and when more is needed.

Why new fish should live in a tank of their own for a few weeks before they move in, what you need, and what to look for.
