The Head-band Surgeonfish, Whitebar Surgeonfish (Acanthurus leucopareius) is a vibrant and fascinating fish species that can be found in the tropical waters of the Indo-Pacific region. Known for its striking appearance and unique behavioral traits, the Acanthurus leucopareius is a captivating addition to the marine environment.
Description & Characteristics
The Acanthurus leucopareius is a moderately sized fish that can reach a maximum length of 25.0 cm. Its body is characterized by a deep, oval shape with a prominent dorsal fin and a slightly forked tail. The most distinctive feature of this surgeonfish is the presence of a broad, white band that runs horizontally along the head, just above the eyes. This band serves as a striking visual marker that distinguishes the Acanthurus leucopareius from other surgeonfish species. The body coloration can vary depending on the individual and the environment, ranging from olive green to grayish-brown with a subtle yellow tinge.
Habitat and Occurrence
The Acanthurus leucopareius is typically found in shallow reefs, lagoons, and seaward slopes, inhabiting a depth range of 1.0 to 85.0 meters. This species prefers coral reefs and rocky habitats, especially those with abundant algae growth. As a result, the Acanthurus leucopareius is a common sight in tropical and subtropical waters, particularly within the Indo-Pacific region.
Taxonomy
The Acanthurus leucopareius belongs to the Class: Teleostei, Order: Acanthuriformes, and Family: Acanthuridae. The Teleostei is a diverse group that represents the majority of bony fish, while the Acanthuriformes encompass a variety of surgeonfish, unicornfish, and tangs. The family Acanthuridae includes a wide variety of surgeonfish known for their scalpel-like spines located near the tail.
Feeding
The Acanthurus leucopareius is primarily an herbivorous species, feeding predominantly on algae. They graze on a variety of algae, including filamentous, crustose, and turf algae. In captivity, the Acanthurus leucopareius can be fed a diet of commercially available algae flakes, frozen food (large sort), and even seaweed. This grazing behavior plays a crucial role in maintaining the health and balance of the coral reef ecosystem, as it helps to control the growth of algae and prevent it from outcompeting other organisms.
