Shallow coastal reefs, reef flats, lagoons, rocky shores and surge-exposed areas; juveniles may occur in tide pools and sheltered coastal habitats.
Distribution
Widespread in the tropical Indo-Pacific, from the Red Sea and East Africa across the Indian and Pacific oceans to Hawaii, southern Japan, northern Australia and many central Pacific islands.
Conservation status
Least Concern
Edibility
Edible but generally of modest culinary value. As with other reef fishes, ciguatera poisoning can occur in some areas; avoid eating specimens from places where this risk is known.

Behaviour
Usually diurnal and social, occurring in groups or loose schools above reefs. Adults can be territorial, especially males guarding eggs; they may boldly approach divers near nesting sites.
Observation zones
Shallow reef, reef flat, lagoon, rocky coast, tide pool and surge zone.
Diet
An omnivore feeding mainly on zooplankton, filamentous and benthic algae, and small benthic invertebrates such as crustaceans.
Reproduction
Oviparous
Identification marks
Deep, laterally compressed damselfish with five dark vertical bars on a pale silvery to yellowish body. A dark spot is usually present high on the caudal peduncle; the back may appear yellowish.
Similar species
Often confused with other barred Abudefduf sergeants. Confirm the five bars and the dark upper caudal-peduncle spot, while also considering geographic range. Abudefduf septemfasciatus typically has more numerous, narrower bars.
Approach rules
Approach slowly and observe from several metres away. Do not chase, touch, corner or feed the fish. Avoid intense flash photography, particularly around nesting males and egg patches.
Protection
Globally assessed as Least Concern on the IUCN Red List. It is not listed in CITES; habitat conservation and responsible reef-fish collection are advisable.
