Habitat
This species primarily inhabits coral reefs and rocky substrates in the Indo-Pacific region, favoring shallow waters from 1 to 30 meters deep. They are commonly found around lagoons, seaward reefs, and areas with strong currents that support algal growth.
Diet
The Orange band surgeonfish mainly feeds on benthic algae, which it scrapes from rocks and coral surfaces using its specialized teeth. They are diurnal grazers, actively feeding during the day to control algae populations and maintain reef health, occasionally supplementing with small invertebrates.
Behavior
These fish are highly social, often forming schools to forage and evade predators, but they can become territorial around feeding areas. They are diurnal, actively swimming and grazing during the day, and retreating to crevices or under coral at night for protection. Orange band surgeonfish use their caudal spines aggressively when threatened, and they exhibit coordinated schooling to confuse predators.
Conservation Status
Listed as Least Concern by IUCN.
