Common name: Sailfin Tang

General Information

The Sailfin Tang, scientifically known as Zebrasoma veliferum, is a striking addition to any marine aquarium. Known for its distinctive tall dorsal fin and vibrant coloration, it is a favorite among aquarists. The Sailfin Tang's body is adorned with a pattern of vertical stripes and spots, creating a visually captivating display. This species is native to the Indo-Pacific region, where it inhabits coral-rich lagoons and outer reef slopes.

In the aquarium trade, the Sailfin Tang is appreciated for its beauty and its role in algae control, as it grazes on filamentous algae. This makes it a valuable addition to reef tanks, helping to maintain a clean and balanced ecosystem. However, due to its size and active nature, it requires a spacious tank to thrive.

Care

Caring for a Sailfin Tang requires a commitment to providing a large and stable environment. These fish can grow quite large and are best kept in tanks with a minimum volume of 500 liters (130 gallons). A well-aerated tank with plenty of swimming space and hiding spots is essential. They thrive in a reef setup with live rock, which provides both grazing opportunities and shelter.

Regular water changes and high-quality filtration are important to maintain water quality. Sailfin Tangs are sensitive to poor water conditions, which can lead to stress and disease. A stable temperature and pH are crucial to their health and well-being.

Diet and Feeding

In the wild, Sailfin Tangs are herbivores, primarily feeding on algae. In captivity, they should be provided with a diet rich in marine algae, supplemented with high-quality flake or pellet foods designed for herbivorous fish. Offering a variety of vegetables, such as spinach or nori, can also be beneficial.

Feed them small amounts several times a day, ensuring they have enough to graze on throughout the day. This mimics their natural feeding behavior and helps prevent issues related to malnutrition.

Behavior and Compatibility

Sailfin Tangs are generally peaceful but can become territorial, especially in smaller tanks or when housed with other tangs. They are best kept with similarly sized, non-aggressive tank mates. Providing ample space and hiding spots can help reduce territorial behavior.

They are reef-safe and can coexist with a wide range of invertebrates and corals, making them suitable for community reef tanks. However, caution should be taken when introducing them to tanks with other tangs, as aggression can occur.

Reproduction

Breeding Sailfin Tangs in captivity is challenging and rarely achieved. They are egg scatterers, releasing eggs and sperm into the water column. Successful breeding typically requires large, specialized setups and is not commonly attempted by hobbyists.

Health and Common Issues

Sailfin Tangs are susceptible to common marine diseases such as ich and marine velvet. Quarantining new additions and maintaining high water quality are essential preventive measures. Regular observation for signs of stress or disease can help catch issues early.

Ensuring a varied and nutritious diet, along with stable water parameters, contributes to their overall health and longevity. With proper care, Sailfin Tangs can live for several years in captivity.

Habitat

In the wild, Sailfin Tangs are found in coral-rich environments of the Indo-Pacific region. They inhabit lagoons and outer reef slopes, where they graze on algae. These environments are characterized by clear, warm waters with plenty of coral cover and rocky substrates, providing both food and shelter.
