Distribution and habitat

The distribution area of Centropyge aurantia is the western Pacific, from Indonesia and the Great Barrier Reef to Samoa, where they mostly live on coral and sponge covered outer reefs to a depth of 60 m.


They need a well-structured aquarium with a reef structure that offers hiding, resting and covering possibilities, with living stones that they can graze on (sponges, algae, small crustaceans) and that act like a biological filter as well as sufficient swimming space. Only lime-rich, heavy metal-free sands, gravel or stones may be used as substrate.

Filters, skimmers and heaters are necessary to ensure water quality, as well as pumps to simulate tides, swells and bottom currents. Lighting must be appropriate for the species' day-night rhythm

Salinity: 33-36 ‰ pH value: 8.1-8.4
Carbonate hardness: 8-10 °KH Nitrate content: 2-8 mg/l
phosphate content: 0.01-0.1 mg/l nitrite content: 0.0-0.05 mg/l

For salinity, an average value should be aimed for, which may only vary slightly by +/- 0.5 ‰. Ammonia and ammonium must not be measurable. Special attention must be paid to constantly good water quality.


In nature, they feed mainly on algae and crustaceans. The change of feed does not always succeed without problems. The food supply should consist of a commercially available, vitamin-enriched frozen special food mix for angelfish or a combination of algae (e.g. spirulina, nori), chopped shrimp, crab and mussel meat with live and frozen food, such as mysis, krill, bosmids and artemia, as well as live cyclops, which also serve to keep them busy. It is recommended to feed small portions several times a day (3-5 times)

Regular and varied feeding promotes health and increases resistance.

Behaviour and compatibility

It is recommended to keep them in pairs. To avoid ranking fights, they should be placed in the aquarium at the same time, with one of the animals being significantly larger. The dominant, larger animal always develops into the male. They are territorial and can sometimes be aggressive towards other dwarf angelfish with similar coloration or body shape.

Sex dimorphism

They are protogynous hermaphrodites, i.e. most males develop from functional females. External sexual characteristics are not known.

Reproduction and breeding

There are no known reports of successful breeding in the aquarium.


As reef dwellers, they should not be kept in a fish-only aquarium. If kept in pairs, with sufficient activity (live stones) and varied feeding, they can be maintained even in demanding coral tanks, without any attacks on the corals.

If different species are kept together, care should be taken to ensure that the fish match each other in terms of water quality and temperature requirements and social behavior, and that the setup meets the needs of all species kept together. New fish to be introduced must be acclimated slowly to the water in the aquarium
