General information

The Blackspot Surgeonfish, scientifically known as Acanthurus bariene, is a striking marine fish recognized for its robust body and distinctive black spots. It is a member of the Acanthuridae family, which is well-known for the scalpel-like spine located on the caudal peduncle, used for defense and territorial displays.

This species exhibits a brownish to olive body color with vibrant yellow accents on the dorsal and anal fins. The black spots, from which it derives its common name, are prominently displayed on the body and tail.

Care

Blackspot Surgeonfish require a spacious aquarium to accommodate their active swimming behavior and potential size, which can reach up to 50 centimeters in length. They thrive in well-oxygenated water with strong currents and ample room to swim.

A varied diet is crucial for their health, consisting of marine algae, seaweed, and meaty foods. They are herbivores by nature, so providing a constant supply of algae or seaweed is essential to prevent malnutrition.

Reproduction

In the wild, Blackspot Surgeonfish are known to form spawning aggregations. However, breeding them in captivity is challenging due to their large size and complex social behaviors.

Habitat

The Blackspot Surgeonfish is found in tropical and subtropical waters across the Indo-Pacific region. They are commonly associated with coral reefs, where they graze on algae and can be observed in both shallow lagoons and outer reef slopes.

Their natural range extends from the East African coast to the central Pacific, including the Red Sea, Indian Ocean, and as far east as Samoa.
