Descrição da espécie
Geographical Origin and Habitat: Endemic to the Revillagigedo Islands, particularly Clarion Island, off the Pacific coast of Mexico. Inhabits clear water rocky reefs and outer reef slopes exposed to strong oceanic currents.
Taxonomy and Morphology: Member of the Pomacanthidae family. Possesses a deeply compressed oval body with a sharp preopercular spine characteristic of Holacanthus. Grows to a maximum length of 20 cm.
Social Behavior: Solitary and highly territorial as an adult. Juveniles sometimes act as cleaners for larger fish. Displays high intraspecific aggression.
Coloration and Sexual Dimorphism: Juveniles are bright orange with vertical blue bands. Adults lose most of their bands, becoming brilliant orange-gold with olive-brown shading on the posterior body, outlined in electric blue. No sexual dimorphism.
Cuidado, criação e companheiros de tanque
Aquarium Setup: Needs a tank of at least 500 liters with robust rockwork forming caves and territories to reduce stress. A wide open swimming area is also required.
Diet and Feeding: Specialized omnivore. Primarily feeds on sponges, tunicates, and algae in the wild. Provide high-quality commercial sponge-based angelfish foods, sheet algae, and frozen mysis.
Water Quality: Requires pristine water and high oxygen levels. Maintain temperature at 22-26°C, pH 8.1-8.4, and salinity at SG 1.020-1.025. Strong skimming is necessary.
Compatibility and Cohabitation: Avoid keeping with other large angelfish or similarly colored species. Peaceful yet active tankmates like tangs and wrasses are suitable.
Aquarium Breeding: Extremely rare in captivity. They are pelagic spawners that release eggs into the water column during dusk.
Risks and Diseases: Prone to marine ich (Cryptocaryon) and Head and Lateral Line Erosion (HLLE) if water quality or diet is subpar.

Perfil de peixe
- Temperamento
- Territorial
- Semi-aggressive and territorial. Establish them as the last addition. They will dominate smaller timid fish.
- Dieta
- Omnivore
- Requires a specialized diet including sponges and algae. Offer high-quality frozen angelfish preparations. Supplement with nori.
- Expectativa de vida
- 10-15 years
- Tamanho adulto
- 20 cm
- Proporção sexual
- Solitary
- Usually kept as a single specimen. Pairs can be attempted in very large tanks. Two males will fight to the death.
- Frequência de alimentação
- Twice daily
- Feed at least two to three times daily. Small frequent meals are best. Ensure food contains marine sponges.
- Carga biológica
- Medium
- Angelfish produce a high bioload due to their size and diet. A strong protein skimmer is highly recommended. Regular maintenance is key.
- Fluxo
- Strong
- Moderate to strong flow is preferred. This simulates their natural reef environment. Allow some calm areas behind rocks.
- Risco de salto
- Yes
- They are not prone to jumping. However, a covered tank is always safer. Avoid startling them with sudden lights.
- Reprodução
- Oviparous
- Captive breeding is very difficult. They release eggs and sperm into the water column. Larvae are challenging to raise.
- Compatibilidade e companheiros de tanque
- Reef safe
- They can nip at corals and clams. Best kept in FOWLR tanks. Avoid keeping with other large angelfish.
- Nível do tanque
- All levels
- They roam across all levels of the aquarium. They need plenty of live rock for grazing. Adequate swimming space is essential.
