Epaulette Surgeonfish: Graceful Giant for Your Reef

Bring the majestic beauty of the Epaulette Surgeonfish to your very large marine aquarium. This active and striking tang is a rewarding challenge for dedicated aquarists.

Overview

The Epaulette Surgeonfish (*Acanthurus nigricauda*) is a large, laterally compressed species known for its dusky brown to purplish-grey body. A prominent black streak behind the upper gill opening, often accompanied by a white bar at the caudal fin base, gives this fish its distinctive appearance. Active and constantly grazing, they are a dynamic addition, exhibiting rapid colour changes based on mood or environment.

Care Level

Considered an intermediate to difficult species, the Epaulette Surgeonfish is semi-aggressive, particularly towards other tangs or food competitors. It thrives best as the sole surgeonfish in an exceptionally spacious system with large, active tankmates. Responsible ownership is key for this long-lived species.

Tank Essentials

A minimum of 950 litres (250 US Gallons) is essential to provide ample swimming space for this active fish. Maintain stable water parameters with a pH range of 8.1-8.4 and a temperature of 23-28°C. Strong water flow and excellent oxygenation are crucial for their well-being.

Diet

As a herbivore, the Epaulette Surgeonfish requires a plant-heavy diet. Offer dried seaweed (nori), spirulina-based flakes and pellets multiple times daily. Supplement with vegetable-based frozen foods, ensuring plant matter dominates. Soaking food in vitamin supplements is highly recommended for optimal health.
