The sharp, forward-pointing spines on the caudal peduncle are venomous. Acanthurus lineatus occurs in the Indian Ocean from East Africa to the western Pacific Ocean to the Great Barrier Reef, Japan, Polynesia and Hawaii. The lined surgeonfish is associated with reefs, living in marine waters just a few meters deep. It is benthopelagic. The fish is territorial, with a large male defending a feeding territory and a harem of females. The adults may also school and they gather en masse during spawning. The juvenile is solitary.

The fish is mostly herbivorous, but might eat crustaceans at times. Most of its diet is algae. It grazes during the day. Acanthurus lineatus species found in Australia, in the Indian Ocean have a greater defense rate against intruders. Lined surgeonfish in the Indian Ocean have a smaller body size, allowing them to have greater access and abundance of food, due to hurricane damage to reefs, enhancing the overall algal turfs that Acanthurus lineatus feed on.
