Blue tangs live primarily on hard-coral reefs. They can also be found near soft corals, rubble, seagrass beds, and algal beds. Young fish prefer areas with plenty of cover. Breeding individuals congregate at flat, sandy areas between patches of reef. They shelter in coral holes and crevices. Blue tangs can be found at depths of 2 to 40 meters.
