Each morning, shortly after sunrise, adult yellow tang migrate to shallow turf algae dominated boulder and reef flat habitats to forage over the same few hundred meters squared. These foraging sites are maintained for periods of at least weeks to months. About 1 hour before sunset, they migrate to individual specific spawning locations before moving to nighttime sheltering sites in deeper coral rich and boulder dominated habitats. Yellow tang adults made daily crepuscular migrations of up to 600 m between foraging and spawning or sheltering sites at consistent times relative to sunset and sunrise Yellow tang juveniles are found in deeper coral rich habitats and are site attached with small home ranges throughout this life stage (roughly 4-7 years).
