Convict Surgeonfish: Striped Beauty for Your Marine Aquarium

Bring the captivating patterns of the Indo-Pacific to your home with the distinct Convict Surgeonfish. An active and diligent grazer, this species is a must-have for maintaining a healthy reef environment.

Overview

The Convict Surgeonfish, *Acanthurus triostegus*, is instantly recognizable by its pale body—ranging from white to silvery-grey—adorned with six bold black vertical stripes, including one through each eye. This laterally compressed, oval-shaped fish actively grazes on algae throughout the day. Like all surgeonfish, it possesses a sharp, retractable scalpel-like spine at the base of its tail, used for defense, which requires careful handling.

Care Level

Considered an intermediate to moderate care level species, the Convict Surgeonfish is semi-aggressive, especially towards other tangs or fish of similar body shapes. It can be kept peacefully with diverse, non-aggressive tankmates and is generally reef-safe, making it an excellent addition to established marine setups.

Tank Essentials

A minimum aquarium size of 600 litres is recommended to provide ample swimming room and stable water conditions for this active species. Maintain water temperature between 22-28°C and a pH range of 8.1-8.4. Ensure plenty of live rock for grazing opportunities and hiding spots to reduce stress.

Diet

As a true herbivore and an effective algae eater, the Convict Surgeonfish primarily grazes on filamentous and macroalgae. Supplement its diet with marine-based seaweed (like Nori) attached to a veggie clip, spirulina, and high-quality vegetable flakes. Offer small, frequent feedings throughout the day to support its active metabolism.
