Distribution and habitat
The range of Centropyge aurantonotus is the western Atlantic, from the southern Caribbean to the Brazilian coast around Sao Paulo, where they prefer to live on coral reefs with Acropora cervicornis.
Maintenance
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.
Diet
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.
Important
They are easily confused with Centropyge acanthops, but they have a yellow, slightly transparent caudal fin.
As reef dwellers, they should not be kept in a fish-only aquarium. When kept in pairs, with sufficient activity (live rocks) and varied feeding, they can be maintained even in challenging coral tanks without encroaching 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
