Geographic Range

Queen angelfish, Holacanthus ciliaris , are tropical fish found in coral reefs in the western Pacific Ocean, the Indian Ocean, and the Atlantic Ocean as far south as Brazil. They do not migrate, and they are commonly spotted near the Bahamas and Florida.

Habitat

Queen angelfish are primarily found in coral reefs, which provide shelter and abundant food sources. They can be found at depths up to 70 m. Although they are naturally marine fish, queen angelfish can tolerate changes in salinity. As such, they are often placed in marine aquariums.

Physical Description

Queen angelfish are easily distinguished by their striking coloration, with vibrant yellow accents and variations of gem-like blues. Their distinctive "crown" is speckled dark blue and surrounded by a ring of bright blue. Their tail is yellow. Juveniles have a markedly different coloration than adults, displaying a striped blue and yellow pattern or a solid yellow pattern.

The body of queen angelfish is very flat, with an elongated, continuous dorsal and anal fin with 9 to 15 spines and 15 to 17 soft rays. They have a strong spine at the angle of the preopercle (cheek bone) and lack a well developed pelvic axillary process (fleshy bump at the base of the pelvic fin). Queen angelfish average 45 cm in length and 1.6 kg in mass. Males are generally larger than females.

  • Sexual Dimorphism
  • male larger

Development

After fertilized eggs of queen angelfish float in the water column for 15 to 20 hours, they develop into transparent larvae. Larvae then develop into juveniles, which resemble adults. Larvae feed on plankton and grow rapidly, reaching a size of 15 to 20 mm in their juvenile form.

Reproduction

Queen angelfish are believed to be polygynous, and harems have been observed during courtship and pre-spawning. Harems generally consist of 1 male and up to 4 females. A male courts a female by displaying his pectoral fins, flicking them outward every few seconds. The female then ascends in the water, and the male positions himself below the female. The male touches his snout to her vent (genital) area, rising with the female with his belly close to hers. As the pair rises to about 18 m in depth, they release eggs and sperm.

Queen angelfish spawn seasonally, which occurs during the winter months in Puerto Rico. Spawning peaks once each year, although queen angelfish may spawn more than once during the year. Spawning behavior has been observed within minutes of sunset during the evening. Females can produce 25,000 to 75,000 eggs in one evening. Eggs hatch in 15 to 20 hours, and larvae absorb the yolk sac in the next 48 hours. Larvae feed on plankton and grow rapidly, reaching a size of 15 to 20 mm in their juvenile form.

Once eggs are fertilized, zygotes are left develop into larvae without any parental investment. Juvenile queen angelfish find protection among colonies of finger sponges and corals at the bottom of reefs.

  • no parental involvement
  • pre-fertilization
    • provisioning

Lifespan/Longevity

The lifespan of queen angelfish has not been well documented.

Behavior

Queen angelfish often travel alone or in pairs. Harems have been observed prior to mating, consisting of 1 male and 4 to 5 females. When placed in aquariums, queen angelfish are very aggressive.

Home Range

Little information is available regarding the home range of queen angelfish.

Communication and Perception

Queen angelfish communicate, particularly during mating, through temporary changes in color. Little information is otherwise available regarding the communication and perception of queen angelfish.

Food Habits

Queen angelfish primarily feed on sponges and corals . They also eat other marine invertebrates, including tunicates , jellyfish , hydroids , bryozoans . They may also eat plankton and algae.

  • Primary Diet
  • carnivore
    • eats other marine invertebrates
  • Animal Foods
  • cnidarians
  • other marine invertebrates
  • zooplankton
  • Plant Foods
  • algae

Predation

Queen angelfish may be preyed upon by many larger fish that inhabit coral reefs; however, predation has not been well studied.

Ecosystem Roles

Queen angelfishes feed on sponges , corals and other small invertebrates, and are preyed upon by larger animals that inhabit coral reefs.

Economic Importance for Humans: Positive

Queen angelfish are popular additions to saltwater aquariums because of their beautiful coloration as both juveniles and adults. Because new technologies have allowed hobbyists to effectively care for and keep marine fish, queen angelfish are increasing sought after. In Florida, queen angelfish averaged from $11.16 to $17.84 USD per fish between 1990 and 1998. Retail prices vary with size and range between $60 and $130 USD. Adult mating pairs sell at a premium.

Economic Importance for Humans: Negative

There are no known adverse effects of queen angelfish on humans.

Conservation Status

Queen angelfish are considered a species of least concern by the ICUN. Populations are globally stable, although they are harvested in high numbers near Brazil.

the area in which the animal is naturally found, the region in which it is endemic.

Atlantic Ocean

the body of water between Africa, Europe, the southern ocean (above 60 degrees south latitude), and the western hemisphere. It is the second largest ocean in the world after the Pacific Ocean.

body of water between the southern ocean (above 60 degrees south latitude), Australia, Asia, and the western hemisphere. This is the world's largest ocean, covering about 28% of the world's surface.

native range

the area in which the animal is naturally found, the region in which it is endemic.

tropical

the region of the earth that surrounds the equator, from 23.5 degrees north to 23.5 degrees south.

saltwater or marine

mainly lives in oceans, seas, or other bodies of salt water.

reef

structure produced by the calcium carbonate skeletons of coral polyps (Class Anthozoa). Coral reefs are found in warm, shallow oceans with low nutrient availability. They form the basis for rich communities of other invertebrates, plants, fish, and protists. The polyps live only on the reef surface. Because they depend on symbiotic photosynthetic algae, zooxanthellae, they cannot live where light does not penetrate.

ectothermic

animals which must use heat acquired from the environment and behavioral adaptations to regulate body temperature

heterothermic

having a body temperature that fluctuates with that of the immediate environment; having no mechanism or a poorly developed mechanism for regulating internal body temperature.

bilateral symmetry

having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.

metamorphosis

A large change in the shape or structure of an animal that happens as the animal grows. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. Butterflies have complete metamorphosis, grasshoppers have incomplete metamorphosis.

polygynous

having more than one female as a mate at one time

iteroparous

offspring are produced in more than one group (litters, clutches, etc.) and across multiple seasons (or other periods hospitable to reproduction). Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes).

seasonal breeding

breeding is confined to a particular season

sexual

reproduction that includes combining the genetic contribution of two individuals, a male and a female

fertilization

union of egg and spermatozoan

external fertilization

fertilization takes place outside the female's body

having the capacity to move from one place to another.
