Species description
Geographical Origin and Habitat: Central Pacific: Johnston Atoll and Hawaiian Islands, deep reefs.
Taxonomy and Morphology: Belongs to the family Pomacanthidae, genus Centropyge. Features a slender, streamlined body typical of water column feeders.
Social Behavior: Active and highly active species. Lives primarily in hierarchical groups or small harems, swimming freely above coral formations.
Coloration and Sexual Dimorphism: Intense and brilliant coloration. Dominant males exhibit bright colors during courtship displays. Females present duller shades.
Care, breeding and tankmates
Aquarium Setup: Requires a marine aquarium of at least 150 liters with live rock arranged to create shelters while leaving ample space for swimming.
Diet and Feeding: Carnivorous. Provide high-quality frozen foods like mysis and brine shrimp along with vitamin-enriched marine pellets.
Water Quality: Excellent and stable water quality: temperature 22.0-26.0 °C, pH 8.1-8.4, and salinity stabilized at 1.020-1.025 with strong skimming.
Compatibility and Cohabitation: Reef safe. Compatible with peaceful reef fishes. Avoid housing with highly aggressive tankmates.
Aquarium Breeding: Pelagic spawning; captive reproduction is not documented in private aquariums.
Risks and Diseases: Primary risk is jumping out of the tank when startled. A tight lid or mesh cover is strictly required.
