Where Cherubfish has been recorded
GBIF occurrence records for Centropyge argi, mapped and tabulated by country.
18,670 georeferenced occurrence records with coordinates are published for Centropyge argi through GBIF, from 31 countries or marine areas. This page maps those records and lists where they come from. Occurrence records reflect where people have looked as well as where the species lives, so well-surveyed coastlines are over-represented.

Appearance & Taxonomic Identity
The orangeback angelfish is a small marine species of ray-finned fish within the family Pomacanthidae, reaching a maximum total length of just eight centimetres. Its colouration is strikingly divided: the head, upper flanks, dorsal fin, and caudal fin glow in a warm golden yellow, while the lower flanks and anal fin are a deep black densely peppered with purple spots. A vivid blue ring encircles each eye, adding a final accent to an otherwise bold two-tone palette. The species carries several common names across regions, including flameback angelfish and African pygmy angelfish, while South African observers affectionately call it the Jumping Bean or simply the Bean. Taxonomically, it was first formally described in 1922 by English ichthyologist John Roxborough Norman under the name Holacanthus acanthops, with Durban designated as the type locality. The specific epithet acanthops derives from the Greek words for "spine" and "eye," referencing a small rearward-pointing spine situated beneath the eye. In certain modern classifications, the species is further grouped within the subgenus Xiphipops.
Geographic Range Across the Western Indian Ocean
The orangeback angelfish is endemic to the western Indian Ocean, where its range stretches across a remarkable sweep of coastlines and island chains. Along the East African mainland, it has been documented from the waters off Somalia all the way south to East London in the Eastern Cape Province. Its distribution extends to several major island groups, including Madagascar, the Seychelles, the Comoros, the Chagos Islands, and the Mascarene Islands. Moving into the broader Asian region, records exist from the Gulf of Aden and the Arabian Sea off Yemen, with sightings specifically noted around Socotra and the Omani coast, as well as the Maldives. Perhaps most surprisingly, the species has also been recorded from the Cocos (Keeling) Islands, an Australian external territory situated in the central Indian Ocean. This wide but regionally concentrated distribution underscores the fish's affinity for the western reaches of the Indian Ocean basin, spanning both continental shelf habitats and scattered island archipelagos over thousands of kilometres.
Social Structure & Reproductive Biology
Living at depths between one and seventy metres, the orangeback angelfish favours areas rich in coral and coral rubble, where it tucks itself into crevices for shelter. It shows a clear preference for zones with dense algal growth, feeding primarily on algae supplemented by small invertebrates. One of the most fascinating aspects of this species is its social nature: rather than being solitary, it is typically encountered in small groups of up to ten individuals. These groups operate under a protogynous hermaphroditic system, meaning every member begins life as a female. The most dominant female in the group transitions into a male, and remarkably, this sex change is reversible should that individual lose its dominant status. Spawning occurs at dusk in a distinctive ritual: the male bites the female on the abdomen to trigger egg release, then fertilises the eggs, which are simply released to drift with the ocean current. This pelagic spawning strategy, combined with the fluid social hierarchy, gives the species a dynamic and ever-shifting group structure.
Aquarium Trade & Human Connection
Beyond its natural coral-rubble habitats, the orangeback angelfish has found a second life in the aquarium trade, where it is both common and popular among marine display tank keepers. Its compact size of eight centimetres, vivid golden-and-black colouring, and social group size of up to ten individuals make it a practical and visually striking addition to reef aquaria. Importantly, the species has been bred in captivity, offering an alternative to wild-caught specimens. In South African waters, where it was first formally described by English ichthyologist John Roxborough Norman in 1922 with Durban designated as the type locality, the fish carries a distinctive local nickname: the Jumping Bean, or simply the Bean. The species' broad distribution across the western Indian Ocean, spanning from the East African mainland through Madagascar and the Seychelles to the Maldives and even the Cocos (Keeling) Islands, means it is encountered by divers and collectors across numerous countries and territories. Its placement within the subgenus Xiphipops in certain taxonomic frameworks also reflects ongoing scholarly effort to refine the classification of pygmy angelfishes, keeping the species at the intersection of both the aquarium hobby and academic ichthyology.
Frequently Asked Questions
How many countries has Cherubfish been documented in?
Cherubfish occurrence data spans 31 different countries or marine regions worldwide. These records are compiled through the GBIF biodiversity database.
How many Cherubfish sightings are on record?
There are 18,670 georeferenced occurrence records with coordinates published for this species. The distribution page samples 3,000 of those points to render its visual map.
Why does the Cherubfish map only show 51 locations?
The page plots 51 distinct mapped locations to keep the visualization readable, even though the full dataset contains nearly 19,000 individual records. A subset of 3,000 records is sampled for the map display.
Where does the Cherubfish distribution data come from?
All records are pulled from GBIF, which aggregates biodiversity data from multiple contributing institutions. The species is identified under taxon key 2396546 in that database.
Does the Cherubfish distribution map include inland records?
Five inland records were excluded from the mapping because they likely represent aquarium escapes or misidentifications rather than natural marine populations. The focus remains on coastal and oceanic sightings.
