Eared Angel (Pomacanthus chrysurus): Breeding Guide
Pomacanthus chrysurus is a rarely seen Western Indian Ocean angel that, like its relatives, spawns pelagic eggs in open water and is not home-bred. Its planktonic larvae drift in the ocean, so this guide describes wild reproduction.
Overview
Pomacanthus chrysurus, the Goldtail or Eared angel, is restricted to the Western Indian Ocean from the Gulf of Aden to Natal in South Africa, including the Seychelles, Comoros and Madagascar. FishBase lists a maximum standard length of about 33 cm and a depth range of roughly 1 to 25 m on coral-rich reefs.
FishBase records a low trophic level for the species and notes that it is seldom seen in the aquarium trade. Juveniles carry stripes on the head, a typical Pomacanthus feature, before transforming to the adult pattern.
Sexing
There is no documented external colour difference between the sexes. As in the genus, a breeding pair would normally be formed by growing young fish together rather than by visual sexing.
Spawning Behavior & Trigger
Detailed spawning has not been documented for this rarely studied species in the consulted sources. As a large Pomacanthus, it is expected to be an oviparous, pelagic pair spawner that rises off the reef to release eggs and sperm into open water, in line with its close relatives.
Related large angels spawn at dusk, so twilight is the expected trigger; species-specific timing for P. chrysurus is not available.
Egg & Fry Care
Following the genus pattern, the eggs would be pelagic and float into the plankton, hatching into minute larvae that depend on natural ocean micro-plankton during a long larval phase.
Because the eggs disperse in open water and the larvae need ocean plankton, there is no nest to manage, and the consulted sources report no captive rearing of this species.
Common Challenges
- The species is rare in the trade, so obtaining a compatible pair is difficult.
- Pelagic eggs and larvae require micro-plankton feeds unavailable in aquaria.
- Large adult size and a sponge-leaning diet make conditioning broodstock impractical at home.
