Common name: Purple Queen Anthias

Scientific name: Pseudanthias pascalus (Jordan & Tanaka, 1927)

General Information

The Purple Queen Anthias (Pseudanthias pascalus) is a stunningly vibrant fish that adds a splash of color to any aquarium. Known for its striking purple and pink hues, this species is a favorite among aquarists seeking to create a visually captivating reef tank. Native to the Indo-Pacific region, including areas such as the Philippines, Indonesia, and the Great Barrier Reef, these fish inhabit coral reefs and lagoons at depths ranging from 10 to 50 meters.

Despite their beauty, Purple Queen Anthias are considered challenging to keep due to their specific dietary and environmental needs. They are often found in large schools in the wild, which makes them a fascinating addition to community tanks when kept in groups. Their active swimming behavior and social dynamics make them a joy to observe.

Care

Purple Queen Anthias require a well-established aquarium with stable water parameters. They thrive in tanks with plenty of live rock for hiding and foraging, as well as open swimming spaces. A tank size of at least 300 liters is recommended for a small group, as these fish are active swimmers and need ample room to move.

Strong water flow and high oxygen levels are essential to mimic their natural reef environment. They are sensitive to changes in water quality, so regular maintenance and monitoring are crucial. Providing a dimly lit environment or shaded areas can help reduce stress, as they are accustomed to deeper reef zones with less intense lighting.

Diet and Feeding

In the wild, Purple Queen Anthias are planktivores, feeding on zooplankton and other small organisms. In captivity, they require frequent feedings of high-quality, nutrient-rich foods to maintain their health and vibrant coloration. Offer a variety of foods, such as frozen mysis shrimp, brine shrimp, and finely chopped seafood, along with specialized marine fish pellets or flakes.

Feed them at least three times a day in small portions to replicate their natural feeding habits. Using an automatic feeder can help maintain a consistent feeding schedule, especially for busy aquarists. Supplementing their diet with vitamin-enriched foods can further enhance their immune system and coloration.

Behavior and Compatibility

Purple Queen Anthias are generally peaceful but can be shy, especially when first introduced to a new tank. They thrive in groups, with a recommended ratio of one male to several females to mimic their natural harem structure. Keeping them in groups helps reduce stress and encourages natural behaviors.

They are compatible with other peaceful reef fish, such as gobies, wrasses, and tangs. Avoid housing them with aggressive or overly dominant species, as this can lead to stress and hiding behavior. Providing plenty of hiding spots and live rock structures can help them feel secure.

Reproduction

Like many anthias species, Purple Queen Anthias are protogynous hermaphrodites, meaning they are born female and can change to male if the dominant male in the group is removed or dies. Breeding them in captivity is rare and challenging, as it requires precise environmental conditions and a well-established harem structure.

Health and Common Issues

Purple Queen Anthias are sensitive to poor water quality and can be prone to stress-related illnesses, such as ich and bacterial infections. Quarantine new additions and maintain pristine water conditions to minimize risks. Regular feeding and a varied diet are essential to prevent malnutrition and related health issues.

When selecting a Purple Queen Anthias, look for active, alert individuals with vibrant coloration and smooth, intact fins. Avoid fish that appear lethargic or have visible signs of disease.

Habitat

In their natural habitat, Purple Queen Anthias are found in coral reef environments with moderate to strong water flow. They prefer areas with plenty of overhangs and crevices for shelter. Replicating these conditions in captivity can help them feel more at home and reduce stress.
