Common name: Fowler's Surgeonfish

General Information

The Fowler's Surgeonfish, scientifically known as Acanthurus fowleri, is a striking member of the Acanthuridae family, which includes tangs and surgeonfish. This species is named after the American ichthyologist Henry Weed Fowler. Known for its unique coloration and distinctive body shape, Acanthurus fowleri is a prized addition to large marine aquariums, although it is less commonly seen than other tangs like the Pacific Blue Tang or Yellow Tang.

In the wild, Fowler's Surgeonfish are found in the Indo-Pacific region, inhabiting coral reefs and lagoons. Their natural beauty and active swimming behavior make them a captivating choice for experienced aquarists looking to add a touch of elegance and movement to their tanks.

Care

Caring for a Fowler's Surgeonfish requires a spacious tank with plenty of swimming room, as these fish are active swimmers. A tank of at least 500 liters is recommended to accommodate their size and activity level. They thrive in well-oxygenated water with stable parameters and plenty of live rock for grazing and hiding.

Due to their herbivorous diet, providing a variety of marine algae and vegetable-based foods is essential. Regular feedings of nori, spirulina, and high-quality herbivore pellets will help maintain their health and vibrant coloration.

Diet and Feeding

Fowler's Surgeonfish are primarily herbivores, feeding on algae and plant matter in the wild. In captivity, they require a diet rich in marine algae and vegetable-based foods. Offer them a variety of foods such as nori, spirulina, and herbivore pellets to ensure they receive a balanced diet.

Feed them small portions multiple times a day, ensuring they have constant access to food. This feeding strategy mimics their natural grazing behavior and helps prevent stress-related health issues.

Behavior and Compatibility

Fowler's Surgeonfish are generally peaceful but can exhibit territorial behavior, especially in smaller tanks or when introduced to new tank mates. They are best kept with other peaceful species and can coexist with other tangs if adequate space and resources are provided.

While they are not aggressive, they may show dominance over smaller or similar-shaped fish, particularly if they feel their territory is being encroached upon. Providing ample space and hiding spots can help mitigate any aggressive tendencies.

Reproduction

Breeding Fowler's Surgeonfish in captivity is challenging and rarely achieved. They are pelagic spawners, releasing eggs and sperm into the open water column. Successful breeding requires specific environmental conditions that are difficult to replicate in home aquariums.

Health and Common Issues

Fowler's Surgeonfish are generally hardy but can be susceptible to common marine diseases such as marine ich and lateral line erosion. Maintaining optimal water quality and providing a balanced diet are crucial for preventing these issues.

When selecting a Fowler's Surgeonfish, look for individuals with vibrant colors and active swimming behavior. Avoid fish that appear lethargic or have visible signs of disease.

Habitat

In the wild, Fowler's Surgeonfish are found in the Indo-Pacific region, particularly around coral reefs and lagoons. They prefer warm, clear waters with abundant coral and algae growth, which provide both food and shelter. Replicating these conditions in captivity is essential for their well-being.
