Common name: Elongate Surgeonfish

General Information

The Elongate Surgeonfish, scientifically known as Acanthurus mata, is a striking species that captivates aquarists with its elongated body and vibrant blue lines. Native to the Indo-Pacific region, this fish is a member of the Acanthuridae family, which includes other popular surgeonfish species. Known for its adaptability and unique appearance, the Elongate Surgeonfish is a prized addition to large marine aquariums.

In the wild, the Acanthurus mata plays an important role in maintaining the health of coral reefs by grazing on algae. This natural behavior helps prevent algae overgrowth, which can be detrimental to coral health. In the aquarium trade, its unique appearance and ecological role make it a favorite among hobbyists who appreciate its contributions to a balanced marine ecosystem.

Physically, the Elongate Surgeonfish is characterized by its sleek, elongated body and distinctive blue lines that run horizontally along its sides. These lines become more pronounced with age, and its overall coloration can vary from grayish-blue to a more vibrant blue, depending on its environment and diet. Its scalpel-like caudal spine is a defining feature of surgeonfish, used for defense and establishing territory.

Care

Caring for the Elongate Surgeonfish requires a spacious aquarium, as this species is an active swimmer that enjoys ample room to roam. A tank of at least 500 liters (approximately 130 gallons) is recommended to accommodate its size and activity level. The aquarium should be well-filtered and provide stable water conditions, with plenty of live rock structures for grazing and exploration.

To mimic its natural habitat, the tank should include a mix of open swimming areas and crevices for hiding. Incorporating live rock not only provides grazing opportunities but also helps maintain water quality by supporting beneficial bacteria.

Diet and Feeding

The Elongate Surgeonfish is primarily herbivorous, feeding on a variety of algae in the wild. In captivity, a diet rich in marine-based algae, such as nori and spirulina, is essential to meet its nutritional needs. Supplementing with high-quality herbivore pellets and occasional vegetable matter, like blanched spinach or zucchini, can ensure a balanced diet.

Feeding should occur several times a day to mimic its natural grazing behavior. Providing a variety of foods helps prevent nutritional deficiencies and promotes vibrant coloration.

Behavior and Compatibility

Generally peaceful, the Elongate Surgeonfish can be a good addition to a community tank with other non-aggressive species. However, it may exhibit territorial behavior towards other surgeonfish, especially if space is limited. Ensuring adequate swimming space and hiding spots can help mitigate potential aggression.

The Elongate Surgeonfish is not known to be toxic and poses no specific safety concerns for other tank inhabitants. It is compatible with a range of reef-safe species, but care should be taken to avoid housing it with overly aggressive or territorial fish.

Reproduction

Breeding the Elongate Surgeonfish in captivity is challenging and rarely achieved. This species is known to spawn in the wild, releasing eggs and sperm into the water column, but replicating these conditions in an aquarium setting is difficult. Successful breeding would require a large, specialized setup to accommodate their natural spawning behaviors.

Health and Common Issues

With proper care, the Elongate Surgeonfish is a hardy species, though it can be susceptible to common marine ailments such as ich and marine velvet. Maintaining optimal water quality and providing a stress-free environment are key to preventing disease. Regular observation and prompt treatment of any health issues can help ensure the well-being of this vibrant species.

When selecting an Elongate Surgeonfish, choose individuals that are active, alert, and free of visible signs of disease. A healthy fish will display vibrant colors and smooth, intact fins.

Habitat

The natural habitat of the Elongate Surgeonfish includes coral reefs and lagoons throughout the Indo-Pacific region. It is commonly found in areas with abundant algae growth, where it can graze freely. Replicating these conditions in captivity involves providing a stable, algae-rich environment with good water flow and quality.

Conservation Status

Currently, the Elongate Surgeonfish is not listed on the IUCN Red List, indicating that it is not considered at immediate risk. However, like many marine species, it faces potential threats from habitat degradation and overfishing. Responsible aquarium practices can help support conservation efforts and reduce pressure on wild populations.
