Common name: Masked angelfish

General information

The Masked Angelfish, Genicanthus personatus, is a highly sought-after species in the marine aquarium trade, known for its striking appearance and unique sexual dimorphism. Males and females exhibit different color patterns, with males sporting a bold black mask over their eyes and a predominantly white body, while females have a more subdued coloration with a silver to white body and orange to yellow accents.

Endemic to the Hawaiian Islands, particularly around the Northwestern Hawaiian Islands, this species is often found in deep reef environments. Due to their rarity and the depth at which they are found, they command a high price in the aquarium trade.

Care

Masked Angelfish require a large, well-established aquarium with plenty of swimming space and live rock for grazing. They are generally peaceful but can be territorial with other angelfish. A varied diet of marine algae, spirulina, mysis shrimp, and other high-quality angelfish preparations will help maintain their health and coloration.

Reproduction

In the wild, Genicanthus personatus forms harems consisting of one male and several females. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. Captive breeding is rare, but with proper conditions and a group of individuals, it may be possible to observe spawning behavior.

Habitat

The Masked Angelfish is typically found at depths ranging from 10 to over 150 meters in the wild, often in areas with strong currents. They prefer steep drop-offs and caves where they can find shelter and food. Their natural range is limited to the Hawaiian archipelago.
