African Flameback Angel Care Guide

Centropyge acanthops is a small western Indian Ocean dwarf angelfish with golden-yellow upperparts and a deep blue lower body.

Compiled by Aquairi from published sources · Published · Updated

Overview

Centropyge acanthops, the African pygmy or orangeback angelfish, is a dwarf angel of the family Pomacanthidae, originally described as Holacanthus acanthops by Norman in 1922. The head, upper flanks, dorsal fin and tail are golden yellow, while the lower body and anal fin are blue with dense purple spotting and blue-ringed eyes. It reaches about 8 cm.

Taxonomy

  • Family: Pomacanthidae
  • Genus: Centropyge
  • Scientific name: Centropyge acanthops

Habitat

Found across the western Indian Ocean, including East Africa from Somalia to the Eastern Cape, Madagascar, the Seychelles, Comoros, Mascarene and Chagos Islands and the Maldives. It occurs over coral and coral rubble with dense algal growth at depths of about 1-70 m.

Tank requirements

  • Minimum tank volume: 200 L
  • Temperature: 24-26 °C
  • pH: 8.1-8.4
  • Specific gravity: 1.024-1.026
  • dKH: 8-12
  • Adult size: 6-8 cm
  • Lifespan: 8-15 years

Diet

Grazes on algae and small invertebrates. In aquaria it needs a mature tank with microalgae for grazing plus marine algae and small prepared foods.

Reef compatibility

Reef compatibility is variable but it is generally considered one of the more reef-tolerant dwarf angels; it may still sample coral polyps. Maintain specific gravity 1.024-1.026 and dKH 8-12.

Compatibility

Semi-aggressive, especially toward other dwarf angels; avoid keeping multiple Centropyge in one tank and avoid aggressive damsels. Suitable tankmates include tangs, clownfish, wrasses and gobies.

Breeding

A social species often found in groups of up to ten fishes; it is a protogynous hermaphrodite where the dominant female becomes male. It spawns at dusk and has been bred in captivity.

Conservation status

IUCN Red List: Least Concern. It is common in the aquarium trade.

Centropyge acanthops (African Flameback Angel) Breeding Guide

Overview

Centropyge acanthops is a small dwarf angelfish of the western Indian Ocean, recorded from the East African coast and across Madagascar, the Seychelles, the Maldives and the Arabian Sea. It reaches about 8 cm and grazes on algae and small invertebrates. It is one of the smaller and more active dwarf angels, but like the rest of the genus it is not reared by aquarists outside specialist larviculture.

Sexing

The species is a protogynous hermaphrodite in which the most dominant female in a group becomes male; this change can be reversed if that individual loses its dominant status. Sex therefore tracks social hierarchy rather than fixed external markers, so juveniles cannot be reliably sexed by eye.

Spawning Behavior & Trigger

Centropyge acanthops is social and is typically encountered in groups of up to ten fish. Reproduction follows the genus pattern: courtship intensifies in the late afternoon and peaks at dusk, when a female rises into the water column with the male nuzzling her vent and releases pelagic eggs near the top of the ascent. The eggs float upward on an internal oil droplet.

Egg & Fry Care

Eggs in this genus are transparent, spherical and roughly 0.6-0.7 mm across. Hatching larvae are minute, exhaust the yolk sac in about three days and then require very small live prey such as copepod nauplii to begin feeding, because rotifers exceed the gape of the first-feeding mouth. No parental care occurs, and larval rearing is the limiting step for captive offspring.

Common Challenges

  • Eggs are released into open water and cannot be collected from a reef display.
  • First-feeding larvae need copepod nauplii rather than standard rotifers.
  • Stable social grouping is difficult in confined aquaria due to dominance conflicts.
  • Captive offspring have only come from dedicated larviculture, not home tanks.
