Captive breeding / propagation

The offspring of Genicanthus personatus are possible. Unfortunately, the number of offspring is not large enough to cover the demand of the trade. If you are interested in Genicanthus personatus, please ask your dealer for offspring. If you already own Genicanthus personatus, try breeding yourself. This will help to improve the availability of offspring in the trade and to conserve natural stocks.

Husbandry

Genicanthus personatus Randall, 1975

Genicanthus personatus also known as the Masked Angelfish is endemic to Hawai'i, rarely seen around the Main Hawaiian Islands, but is fairly common at Kure, Midway, Pearl and Hermes Reefs.

Genicanthus personatus is one of the few angelfish to exhibit dramatic sexual dimorphism. Like other angelfishes, it begins its mature life as a female, then eventually changes sex to become a male. It is suggested that starting out with 2 or more females is the best way to form a breeding group, allowing the dominant fish to become the male over the course of a few months.

The Masked Angelfish male is pearly white with anterior portion of the head, from the snout to just behind the eye, yellow orange; anterior half of the caudal fin black; dorsal and anal fins white with a broad orange band distally; the pectoral and pelvic fins orange. Female pearly white with anterior portion of the head, from the snout to just behind the eye black or gray; anterior half of the caudal fin also black; distal portion of pelvic fins orange.

Genicanthus personatus are not schooling fish, but are also less territorial and more passive towards members of the same species. Being planktivores, a diverse diet with frequent feedings is the norm for successfully meeting their dietary needs in captivity. Feed prepared and frozen foods like krill, raw table shrimp, squid, clam and mussel. It is also a good idea to occasionally supplement with some type of herbivore diet containing marine algae and supplement with a sponge fortified formula for Angelfish.

The cooler waters (20 – 23° C) and deeper depths (30 – 120 m) from which they hail likely contribute to the difficulty in acclimating Genicanthus personatus.

Kommen extrem selten in den Handel, gehen dann eigentlich immer nach Japan. Preis für ein Paar liegt bei ca. 25.000 Dollar!
Ist im Waikiki Aquarium bereits einmal gezüchtet worden.

Hawaii and Midway Atoll; 21 cm; rare
Deepwater, more than 60 meters in Hawaii, but shallower in Midway; aquacultured in
Oahu; males with yellow-orange band on dorsal and anal fins; named by its distinct face
(= personatus); expensive for average aquarists to afford; large ones are hard to maintain
