| Origin | Western Pacific — Indonesia to Japan and Australia |

Behavior
Sweetlips are highly desirable as juveniles for their dramatic spotted, wriggling patterns, but grow very large and transform significantly in color as adults. Juvenile behavior includes an exaggerated, undulating swimming motion thought to mimic toxic flatworms. A challenging but rewarding fish for large FOWLR systems.
Diet & Feeding
Carnivore. Feeds on small fish, crustaceans, and worms. Juveniles may be difficult to feed — offer live brine shrimp initially, transitioning to frozen mysis and chopped seafood.
Cautions
Grows very large. Juveniles need careful feeding to avoid starvation. Not reef safe as adults.
