Common name: Whitebar Surgeonfish

General Information

The Whitebar Surgeonfish, scientifically known as Acanthurus leucopareius, is a captivating species within the aquarium trade, appreciated for its striking appearance and active behavior. The species is named for the distinctive white bar located just behind its eye, which stands out against its otherwise dark body. This surgeonfish is a member of the Acanthuridae family, which is renowned for the scalpel-like spines on either side of the tail, a characteristic feature of surgeonfish.

In the wild, the Whitebar Surgeonfish plays a vital role in maintaining the health of coral reefs by grazing on algae that can otherwise overgrow and suffocate corals. Its ecological importance makes it a popular choice among reef enthusiasts who aim to create a balanced and thriving marine ecosystem in their aquariums.

Care

Caring for the Whitebar Surgeonfish requires some experience, as they are moderately challenging to keep. They thrive in large, well-established reef aquariums with plenty of swimming space and live rock for grazing. A tank of at least 400 liters (105 gallons) is recommended to accommodate their active nature and potential size.

The tank should mimic their natural habitat with adequate water flow and stable water parameters. Providing an environment that closely resembles their natural reef habitat will help reduce stress and promote healthy behavior.

Diet and Feeding

Whitebar Surgeonfish are herbivores, primarily feeding on algae in the wild. In captivity, they should be offered a diet rich in marine-based algae, supplemented with high-quality pellets or flakes formulated for herbivorous fish. Foods such as nori, spirulina, and mysis shrimp can be provided to ensure a balanced diet.

Feed them two to three times daily, offering portions they can consume within a few minutes. Regular feeding helps maintain their vibrant coloration and supports their overall health.

Behavior and Compatibility

Generally peaceful, the Whitebar Surgeonfish can be a good addition to community reef tanks. However, they may exhibit territorial behavior towards other surgeonfish or similarly shaped species, especially in smaller aquariums.

They are best kept with other peaceful tank mates and should not be housed with overly aggressive species that may intimidate them. Providing ample space and hiding spots can help mitigate any territorial disputes.

Health and Common Issues

With proper care, the Whitebar Surgeonfish can live a long and healthy life in captivity. It's important to maintain high water quality and a balanced diet to prevent common health issues such as ich and lateral line disease.

When selecting a specimen, choose active and alert individuals with clear eyes and smooth, intact fins. Avoid fish that appear lethargic or have visible signs of disease.

Regular water changes and monitoring for signs of stress or illness are crucial in maintaining their health. Quarantining new additions can help prevent the spread of disease within the aquarium.

Habitat

The Whitebar Surgeonfish is naturally found in the Indo-Pacific region, inhabiting coral reefs and lagoons. They are typically found at depths ranging from 1 to 40 meters (3 to 130 feet), where they graze on algae-covered surfaces.

These fish prefer environments with plenty of live rock and coral formations, which provide both food and shelter. Replicating these conditions in a home aquarium helps ensure their well-being and allows them to display natural behaviors.
