The Threadfin Butterfly is an omnivore and mainly feeds on filamentous algae, as well as tears pieces off its invertebrate prey, especially soft corals, worms, anemones, and hard corals. It requires a thick sand bed, rockworks so that the Lined Butterflyfish can freely inhabits the reef crevices, and on sand.
