Eyestripe/Pencil Surgeonfish

The Eyestripe or Pencil Surgeonfish (Acanthurus dussumieri) is a captivating marine fish found predominantly in the coral reefs of the Indo-Pacific region. This species is characterized by its elongated body, which can reach up to 30 cm in length, and its distinctive coloration, featuring a blue body adorned with yellow stripes and a prominent black eye stripe that runs from its eye to the base of its tail. The combination of colors makes it a popular choice among aquarium enthusiasts and collectors alike.

In terms of behavior, the Eyestripe Surgeonfish is known for its active swimming style, often seen darting in and out of coral structures. This species is primarily herbivorous, feeding on algae and other plant materials found on the reef. Its social nature means it can often be seen in small groups, engaging in various behaviors such as grazing and establishing territories. The Eyestripe Surgeonfish also exhibits a unique behavior of using its sharp spines for defense against predators.

Habitat-wise, the Eyestripe Surgeonfish thrives in shallow reef environments, typically residing at depths of 5 to 30 meters. They prefer areas with abundant coral cover, which provides both food and shelter. As a reef-associated species, they play a crucial role in maintaining the health of coral ecosystems by controlling algae growth. This ecological contribution underscores the importance of sustainable harvesting practices for this species in the aquarium trade.

Overall, Acanthurus dussumieri stands out not only for its vibrant appearance but also for its ecological significance within its natural habitat. Its presence in the marine aquarium trade highlights the need for responsible sourcing to ensure the sustainability of this beautiful species.

For successful care of the Eyestripe Surgeonfish, maintaining optimal water parameters is crucial. Ideal conditions include a temperature range of 24-28°C, salinity between 1.020-1.025 ppt, and a pH level of 8.1-8.4. A minimum tank size of 200 liters is recommended to provide ample swimming space and territories for this active fish.

Feeding should include a varied diet primarily consisting of high-quality marine algae, spirulina, and occasional supplements of herbivore pellets or flakes. It is essential to provide multiple feeding stations to accommodate its social nature and reduce competition among tank mates. The Eyestripe Surgeonfish is generally compatible with other peaceful reef species but may display territorial behavior towards its own kind, particularly if space is limited.

Acclimation is vital when introducing this species to a new environment. A slow acclimation process over several hours is recommended to minimize stress. Quarantine procedures should also be implemented for new arrivals to prevent the introduction of diseases into existing systems. Regular monitoring of water quality and fish health will ensure a thriving environment for the Eyestripe Surgeonfish.

The Eyestripe Surgeonfish is suitable for shipping under controlled conditions. It is recommended to pack them in well-oxygenated bags with minimal water volume to reduce stress during transport. A temperature range of 22-26°C should be maintained throughout the shipping process. CITES status for this species is not applicable, but sustainable harvesting practices are essential to protect wild populations.
