Common name: Eyestripe Surgeonfish

General Information

The Eyestripe Surgeonfish, scientifically known as Acanthurus dussumieri, is a captivating marine species cherished by aquarists for its unique appearance and peaceful nature. Named after the French explorer Jean-Jacques Dussumier, this fish is often recognized by the distinctive stripe running through its eye and the vibrant hues of blue and yellow that adorn its body. Its streamlined shape and scalpel-like spine near the tail are characteristic of surgeonfish, a feature that gives the family its name.

In the aquarium trade, the Eyestripe Surgeonfish is valued not only for its beauty but also for its role in maintaining algae levels, making it a functional addition to larger reef tanks. Its presence supports a balanced ecosystem, and its active swimming patterns add dynamic movement to the tank environment.

Care

Caring for the Eyestripe Surgeonfish requires a commitment to providing a spacious and stable environment. A tank of at least 500 liters is recommended to accommodate its active swimming habits and potential size of up to 54 cm in the wild. The aquarium should be equipped with plenty of live rock, providing both grazing surfaces for algae and hiding spots to mimic its natural habitat.

Maintaining high water quality with efficient filtration and regular water changes is essential to ensure the health and longevity of this species. The tank should have good water movement to replicate the currents of its natural reef environment, along with stable temperature and salinity levels.

Diet and Feeding

The Eyestripe Surgeonfish is primarily herbivorous, feeding on algae in the wild. In captivity, its diet should consist of a variety of marine-based algae and seaweed, supplemented with high-quality herbivore pellets and occasional offerings of mysis shrimp or other protein sources to ensure balanced nutrition.

Feeding should be frequent, providing small amounts several times a day to mimic their natural grazing behavior. This helps prevent overfeeding and maintains optimal water quality.

Behavior and Compatibility

Known for its peaceful temperament, the Eyestripe Surgeonfish is generally compatible with a wide range of tank mates, making it a popular choice for community reef tanks. However, it may exhibit territorial behavior towards other surgeonfish, especially in smaller tanks.

While not aggressive, it is important to monitor interactions with other species, particularly during feeding times, to ensure all inhabitants receive adequate nutrition without competition.

Health and Common Issues

With proper care, the Eyestripe Surgeonfish can thrive for many years in captivity. It's crucial to monitor for signs of stress or disease, such as ich or lateral line erosion, which can occur if water quality deteriorates or if the fish is underfed.

When acquiring this species, choose individuals that are active and free of visible blemishes or signs of distress. Quarantining new additions and maintaining a clean, stable environment are key to preventing health issues.

Habitat

The Eyestripe Surgeonfish is native to the Indo-Pacific region, inhabiting coral reefs and rocky substrates. It is commonly found in areas with abundant algae, which forms the basis of its diet. These environments provide the necessary resources for grazing and shelter, supporting its active lifestyle and social behavior.
