Queen Angelfish care guide
Queen Angelfish (Holacanthus ciliaris) — minimum tank 800 L, temperature 24-27 °C, pH 8.1-8.4.
Compiled by Aquairi from published sources · Published · Updated
Overview
The Queen Angelfish (Holacanthus ciliaris) is a large Western Atlantic angelfish reaching about 45 cm. Adults are vivid blue and yellow with an electric-blue "crown" of scales on the forehead — a feature absent in the similar Blue Angelfish (H. bermudensis). Juveniles are dark blue with vertical white bars.
Taxonomy
- Family: Pomacanthidae
- Genus: Holacanthus
- Scientific name: Holacanthus ciliaris
Habitat
Endemic to the tropical Western Atlantic from Florida and the Gulf of Mexico through the Bahamas, Caribbean and Brazil. Adults occupy coral-rich reefs, walls and lagoon flats from about 3 to 70 m depth.
Tank requirements
- Minimum tank volume: 800 L (211.3 US gal)
- Adult size: 35-45 cm
- Temperature: 24-27 °C (75-81 °F)
- pH: 8.1-8.4
- GH: 8-12 °dGH
- Water flow: moderate
- Lifespan: 15-20 years
- Salinity: SG 1.024-1.026
- Carbonate hardness (dKH): 8-12
Diet
An omnivore that grazes primarily on sponges, tunicates and algae. In captivity it requires sponge-based angel formulas, frozen mysis and krill, enriched brine shrimp, dried algae and occasional clam-on-the-shell. A varied diet is essential to prevent head-and-lateral-line erosion.
Compatibility
Territorial and intolerant of conspecifics and other large angels; one per tank in a very large system. Compatible with similarly robust marine fish — large tangs, triggers, groupers and other large angels of different genera in FOWLR setups.
Reef compatibility
Not reef-safe. Adults eagerly sample sponges, soft and stony coral polyps and clam mantles, so the species is restricted to fish-only or FOWLR systems.
Breeding
A pelagic broadcast spawner that forms temporary monogamous pairs. Hybridisation with the closely related Blue Angelfish is documented where ranges overlap. Captive breeding is rare and the trade is supplied by wild collection.
Conservation status
IUCN Red List: Least Concern. The species remains widespread across the Western Atlantic; ornamental collection is managed under regional fishery rules.
Queen Angelfish Breeding Guide
Overview
The queen angelfish (Holacanthus ciliaris) is a large pomacanthid of the western Atlantic, ranging from Florida through the Caribbean to Brazil and out to Bermuda, on coral reefs from shallow water down to about 70 m. It reaches up to 45 cm in length and is assessed as Least Concern (2010) by the IUCN. Home breeding is not established; the following describes documented wild reproduction.
Sexing
The species is a protogynous hermaphrodite. Males hold large territories containing harems of two to four females, and the largest harem female can transform into a male if the territorial male disappears.
Conditioning
No home conditioning protocol is documented. Adults are selective sponge feeders, with 68-90% of the diet made up of sponges, a specialised diet that itself complicates long-term captive care.
Spawning Behaviour & Trigger
Spawning occurs year-round but is observed around the full moon. Courtship involves the male displaying his flanks, flicking his pectoral fins at the female and soaring above her. During spawning the female rises toward the surface with the male beneath her, and a female may release between 25,000 and 75,000 eggs per day.
Egg & Fry Care
The eggs are pelagic and remain suspended in the water for 15-20 hours. Newly hatched larvae carry a large yolk sac and have no functional eyes, gut or fins; after about two days they develop fish-like features and become plankton-eaters. At three to four weeks and 15-20 mm they descend to the reef as juveniles. There is no parental care and no practical way to rear these planktonic larvae at home. As juveniles, the young act as cleaner fish and establish cleaning stations for other reef fishes.
Common Challenges
The size of the fish (requiring very large systems), a sponge-based natural diet, and a pelagic larval phase with tiny first-feeding larvae together place reproduction far beyond home aquaria.
