Common name: Pale-lipped Surgeonfish

General Information

The Pale-lipped Surgeonfish, scientifically known as Acanthurus leucocheilus, is a striking species admired for its unique coloration and active nature. This species is part of the Acanthuridae family, commonly referred to as surgeonfish, which are known for their scalpel-like spines on either side of the tail. These spines serve as a defense mechanism against predators.

The Pale-lipped Surgeonfish is not only popular among hobbyists for its aesthetic appeal but also plays a significant role in the marine ecosystem by grazing on algae. This grazing helps to keep algae levels in check, promoting coral health and biodiversity.

Care

Caring for the Pale-lipped Surgeonfish requires a spacious aquarium with plenty of swimming room. They are active swimmers and benefit from a tank with ample horizontal space. A well-established reef tank with live rock is ideal, as it provides natural grazing opportunities and hiding spots.

Maintaining stable water conditions is crucial for their health. They thrive in aquariums that mimic their natural reef environment, with consistent water parameters and good filtration to ensure high water quality.

Diet and Feeding

Pale-lipped Surgeonfish are primarily herbivorous, feeding on a diet rich in marine algae. In captivity, they should be offered a variety of seaweed and algae-based foods, such as nori or spirulina flakes, to meet their nutritional needs. Supplementing their diet with high-quality herbivore pellets can also be beneficial.

Regular feeding with vegetable matter is essential to prevent nutritional deficiencies and promote vibrant coloration. Occasional treats of mysis shrimp or brine shrimp can be offered but should not replace their primary diet of algae.

Behavior and Compatibility

This species is generally peaceful but can exhibit territorial behavior, particularly towards other surgeonfish. They are best kept in either a single specimen tank or in a large aquarium with plenty of space to minimize aggression.

Pale-lipped Surgeonfish are compatible with a variety of other reef-safe species, including peaceful fish and invertebrates. However, caution should be exercised when housing them with other tangs to avoid territorial disputes.

Health and Common Issues

In captivity, Pale-lipped Surgeonfish can live for over a decade with proper care. Key to their health is maintaining a stable environment and providing a balanced diet rich in algae.

When selecting a specimen, choose individuals that are active and have clear eyes and intact fins. Avoid fish that appear lethargic or have visible signs of disease.

Common health issues include marine ich and lateral line erosion, often related to poor water quality or nutritional imbalances. Regular monitoring and prompt treatment are essential to prevent these conditions.

Habitat

The Pale-lipped Surgeonfish is native to the coral reefs of the Indo-Pacific region, including areas around the Philippines, Indonesia, and Papua New Guinea. They are typically found in shallow reef environments where they graze on algae growing on rocks and coral substrates.

These fish prefer warm, tropical waters with plenty of live rock and crevices to explore. Replicating these conditions in captivity, with stable temperatures and good water movement, will help them thrive.
