Common name: Epaulette Surgeonfish
General Information
The Epaulette Surgeonfish, scientifically known as Acanthurus nigricauda, is a striking species found in the aquarium trade, admired for its unique coloration and active demeanor. Known for the dark band or "epaulette" marking behind its eyes, this fish adds a dynamic presence to any marine aquarium. Its adaptability and resilience make it a popular choice for both novice and experienced aquarists.
In the wild, the Epaulette Surgeonfish plays a crucial role in maintaining the health of coral reefs by grazing on algae, which helps prevent algal overgrowth that can smother corals. This ecological role underscores its importance in both natural and artificial reef settings.

Care
Caring for the Epaulette Surgeonfish requires an understanding of its natural habitat. These fish are best kept in spacious aquariums that allow for ample swimming space. A tank with plenty of live rock will not only provide hiding spots but also serve as a substrate for algae growth, which forms a significant part of their diet.
Due to their active nature, these fish thrive in tanks with strong water movement that mimics ocean currents. Maintaining stable water conditions with efficient filtration is essential for their health and well-being.
Diet and Feeding
Epaulette Surgeonfish are primarily herbivorous, feeding on algae in the wild. In captivity, their diet should include a variety of marine algae, spirulina, and high-quality herbivore pellets. Supplementing their diet with occasional meaty foods like mysis shrimp can provide essential proteins.
Feed them several times a day in small amounts to mimic their natural grazing behavior and prevent overeating, which can lead to water quality issues.
Behavior and Compatibility
Generally peaceful, the Epaulette Surgeonfish can be a harmonious addition to community tanks. However, they can exhibit territorial behavior towards other surgeonfish, especially in confined spaces. Providing ample space and hiding spots can help mitigate aggression.
These fish are best kept with other peaceful species. They are compatible with a variety of reef-safe fish and invertebrates, making them suitable for diverse marine setups.
Health and Common Issues
With proper care, the Epaulette Surgeonfish can live for several years in captivity. It's important to monitor their health regularly, as they can be susceptible to common marine diseases such as ich. Quarantining new additions and maintaining high water quality are key preventative measures.
Habitat
Native to the Indo-Pacific region, the Epaulette Surgeonfish is commonly found in coral reefs and shallow lagoons. They favor environments with abundant algae and clear waters. In captivity, replicating these conditions with stable temperatures and moderate water flow is crucial for their health.
Conservation Status
Currently, the Epaulette Surgeonfish does not have a specific conservation status. However, maintaining sustainable practices in the aquarium trade is essential to prevent over-harvesting and ensure the species' long-term survival.
