Natural History: The Atlantic Blue Tang is found in inshore reef, grassy or rocky areas. It is usually observed in small groups. Juveniles form cleaning stations for green turtles (Chelonia mydas, picking algae and parasites from their scales. The Atlantic Blue Tang has an erect spine on its caudal peduncle that it can use in defense. Juveniles are bright yellow while adults are a deep blue color. This species often hides in cracks and crevices at night to avoid predation.
Husbandry: The Atlantic Blue Tang will likely be aggressive with other tangs but is tolerant and peaceful with fish from other families. If filamentous hair algae is not available in its aquarium in high quantities then its diet should be supplemented with Nori or other types of dried seaweed.
