Cyprinocirrhites polyactis
Family: Cirrhitidae ยท Hawkfish
Also known as: Lyretail Hawkfish, Swallowtail Coral Hawkfish
The Swallowtail Hawkfish is one of the most unusual members of the hawkfish family, distinguished by its deeply forked lyretail and its remarkable habit of swimming freely in the water column rather than perching on the bottom. While most hawkfish are dedicated bottom-dwellers that lack a functional swim bladder, the Swallowtail Hawkfish has adapted to feed on zooplankton in mid-water, making it a fascinating exception to the typical hawkfish lifestyle.
This species displays a warm pinkish to reddish-brown body with lighter underparts and a distinctively forked caudal fin that gives it its common name. Its overall appearance is more streamlined and graceful than most hawkfish, reflecting its active swimming habits. In the aquarium, it can be observed hovering in the water column, darting to capture passing food items, and only occasionally resting on rock surfaces.
The Swallowtail Hawkfish is reef-safe with corals and generally compatible with a wide range of community fish. It is less aggressive than most hawkfish species, though it can still show territorial behavior toward similar-sized fish. Its unique swimming behavior, attractive coloration, and manageable size make it an excellent choice for intermediate aquarists seeking an unusual and engaging hawkfish that defies the typical perching stereotype.
Swallowtail Hawkfish are planktivorous carnivores that feed primarily on zooplankton in the water column. In captivity, they readily accept frozen mysis shrimp, enriched brine shrimp, cyclops, and fine marine pellets. Feed two to three times daily to mimic their natural continuous grazing habit.
The Swallowtail Hawkfish is more peaceful than most hawkfish species and compatible with a wide range of community reef fish. It is less likely to prey on ornamental shrimp than bottom-dwelling hawkfish. Safe with all coral types. May show mild aggression toward similar-shaped fish.
Check CompatibilitySwallowtail Hawkfish are protogynous hermaphrodites. Their mid-water spawning behavior involves pairs releasing pelagic eggs at dusk. Captive breeding is rare but has been attempted by specialist breeders.
