Content context

BCDE canonical profile

Global species information is maintained separately from regional and consumer-specific context.

A dark blue to black pygmy angelfish with a golden-orange head and back and a pale golden caudal fin. It differs from western Atlantic C. aurantonotus.

Structured aquarium care

Responsible care profile

Advisor risk categories are MLL planning precautions rather than measured probabilities. Qualitative source-scoped care and MLL planning precautions. Numerical enclosure and water limits, lifelong nutrition and safe group density remain unverified; natural depth and experimental settings are not aquarium operating presets.

Scoped care foundation

Identity, safeguards and related care references have been reviewed. Genus examples or incomplete species-specific husbandry evidence do not establish exact aquarium limits; read the scope note before stocking.

Temperament
Baensch’s genus level care synthesis warns that coral picking varies by species and individual. MLL precaution: monitor coral and sessile invertebrate condition and retain a separation option; no unconditional reef safety claim is warranted. Assess territorial interactions rather than copying wild harem sizes into an aquarium.
Social plan
Assess individual interactions; no fixed safe group size established.

Water

Species-specific Bob Goemans husbandry recommendation; not an experimental tolerance boundary · Confirm the source animal’s temperature and salinity, document stable oxygenated conditions, and obtain a species-matched operating plan before acquisition. No independently corroborated numerical water prescription is published in this review.

Habitat

MLL precaution: provide secure rock refuges, accessible foraging surfaces and room for the adult to move between territories. Confirm the actual captive history. Research broodstock vessels and experimental temperatures cannot establish universal home-aquarium minimums.

MLL precaution: provide accessible retreat areas without blocking swimming paths.

Light: Set from the animal’s documented holding history; wild depth is not a prescribed light setting.

Flow: MLL precaution: maintain oxygenation and accessible feeding zones; assess individual swimming and resting behaviour.

Feeding

Omnivore · Record individual intake and body condition; no universal feeding frequency established in this review. · Food options: Mysis shrimp, Enriched brine shrimp, Chopped marine shrimp, Spirulina-containing marine food, Appropriately sized marine flakes · MLL precaution: verify established prepared-food acceptance and provide a varied marine diet alongside foraging, tracking intake and body condition. Larval prey and early-development results cannot establish adult nutritional completeness. Avoid relying solely on whatever growth is visible on rock. Source: species-specific aquarium author guidance; meal count is a husbandry recommendation, not a validated nutritional limit.

Compatibility

Baensch’s genus-level care synthesis warns that coral picking varies by species and individual. MLL precaution: monitor coral and sessile-invertebrate condition and retain a separation option; no unconditional reef-safety claim is warranted. Assess territorial interactions rather than copying wild harem sizes into an aquarium.

What the evidence establishes

Museum natural history and named captive observations; management precautions are identified as MLL inferences.

Advisor risk categories are MLL planning precautions rather than measured probabilities. Qualitative source-scoped care and MLL planning precautions. Numerical enclosure and water limits, lifelong nutrition and safe group density remain unverified; natural depth and experimental settings are not aquarium operating presets.

Still unverified

  • Species-matched lifetime adult ration and enclosure dimensions
  • Reliable pair or group introduction and invertebrate-specific outcomes

Acclimation and quarantine

MLL precaution: verify identification, collection and transport history, demonstrated food acceptance and source-water conditions; use a quarantine and transfer plan with a qualified marine aquarium professional. Observe respiration, swimming, injuries and appetite before moving to the display.

Stocking safeguards

Aquarium setting: Home aquarium. Starvation risk: moderate.

After identification, quarantine, feeding and housing assessment.

  • No acquisition without demonstrated food acceptance and appropriate adult housing
  • No assumed safe group size or unverified numerical water presets

Special risks

  • Territorial aggression
  • Individual coral or sessile-invertebrate picking
  • Confusion between African and Brazilian flamebacks

Husbandry Findings and Limits

These findings explain what the cited evidence supports. Facility precautions are identified separately from tested captive outcomes.

Identification and Species Context

A dark blue to black pygmy angelfish with a golden-orange head and back and a pale golden caudal fin. It differs from western Atlantic C. aurantonotus.

Habitat and Distribution

Western Indian Ocean, from African waters through western island groups toward Maldives and Chagos, with Cocos (Keeling) records. Coral rubble habitat with shelter and surface food; the breeder account documents natural harem associations.

Biology and Ecology

Baensch reports raising juveniles from captive eggs using copepods and Artemia. Taiwan Fisheries Research Institute separately documents captive spawning. Culture feasibility does not validate lifetime nutrition.

Responsible Sourcing

Verify documented origin, transport history and individual health. A photograph or aquarium observation does not establish sustainable collection or suitability for every aquarium.

Evidence and Remaining Questions

Species-matched lifetime adult ration and enclosure dimensions Reliable pair or group introduction and invertebrate-specific outcomes Advisor risk categories are MLL planning precautions rather than measured probabilities. Qualitative source-scoped care and MLL planning precautions. Numerical enclosure and water limits, lifelong nutrition and safe group density remain unverified; natural depth and experimental settings are not aquarium operating presets.
