Common name: Masked Angelfish

General Information

The Masked Angelfish, scientifically known as Genicanthus personatus, is a rare and highly sought-after species in the aquarium trade. This stunning fish is renowned for its striking appearance, featuring a predominantly white body with a distinctive black mask covering its eyes and extending to its dorsal fin. Due to its rarity and unique beauty, the Masked Angelfish is considered a prized addition to any marine aquarium.

Native to the Hawaiian Islands, the Masked Angelfish is not commonly found in the pet trade, primarily due to its limited distribution and the challenges associated with capturing and transporting this species. Its rarity and the difficulty of breeding it in captivity contribute to its high value among collectors and enthusiasts.

Care

Caring for the Masked Angelfish requires a well-established aquarium with plenty of live rock and open swimming space. This species thrives in a stable environment that mimics its natural reef habitat, with ample hiding spots and a variety of structures to explore. Maintaining pristine water quality and stable parameters is crucial for the health and well-being of this delicate angelfish.

The Masked Angelfish is best suited for experienced aquarists due to its specific care requirements and sensitivity to changes in water conditions. It is recommended to house this species in a tank of at least 500 liters (approximately 130 gallons) to provide sufficient space for swimming and territory establishment.

Diet and Feeding

In the wild, the Masked Angelfish primarily feeds on zooplankton and small invertebrates. In captivity, a varied diet consisting of high-quality marine pellets, frozen mysis shrimp, and enriched brine shrimp will help meet its nutritional needs. Offering a diverse diet not only supports their health but also enhances their vibrant coloration.

Feed the Masked Angelfish two to three times daily, ensuring that the portions are appropriate for their size and activity level. Regular feeding and a balanced diet are essential to maintain their health and vitality.

Behavior and Compatibility

The Masked Angelfish is generally peaceful and can coexist with a variety of other reef-safe species. However, it may exhibit territorial behavior, especially towards other angelfish or similarly shaped fish. Providing ample space and hiding spots can help mitigate potential aggression.

This species is best kept as a single specimen or in a pair, as they may become aggressive towards conspecifics in confined spaces. When introducing them to a community tank, choose tank mates that are peaceful and not overly aggressive.

Reproduction

Breeding the Masked Angelfish in captivity is extremely challenging and has rarely been achieved. This species is known to form monogamous pairs in the wild, and successful breeding attempts require precise environmental conditions and a deep understanding of their reproductive behaviors.

Health and Common Issues

The Masked Angelfish is susceptible to common marine diseases such as ich and velvet. Maintaining optimal water quality and a stress-free environment can help prevent these issues. Regular monitoring and prompt treatment of any signs of illness are essential to ensure their health.

When selecting a Masked Angelfish, look for individuals that are active, alert, and free from visible signs of disease. Quarantining new additions before introducing them to the main tank is a recommended practice to prevent the spread of potential pathogens.

Habitat

The Masked Angelfish is endemic to the Hawaiian Islands, where it inhabits coral reefs and rocky outcrops at depths ranging from 20 to 100 meters (65 to 330 feet). These environments provide the complex structures and diverse food sources that are essential for their survival.

In captivity, replicating their natural habitat with live rock, coral structures, and adequate swimming space is crucial for their well-being. Maintaining stable water conditions with moderate flow and appropriate lighting will help mimic their natural environment.
