Pomacanthus asfur (Arabian Angelfish)

Overview

  • Native to the Red Sea and western Indian Ocean, commonly inhabiting coral reefs and rocky reef slopes.
  • Recognizable by its striking coloration: a deep blue-black body with a bold vertical yellow band and yellow tail fin.
  • Juveniles display a unique coloration of dark blue with thin vertical white stripes.
  • Known to exhibit territorial behavior and active personality in aquarium settings.

Feeding

  • Primarily omnivorous; natural diet consists of algae, sponges, tunicates, corals, and small invertebrates.
  • Accepts varied foods in aquariums, including angelfish-specific diets, marine algae, mysis shrimp, brine shrimp, and finely chopped seafood.
  • Requires multiple daily feedings to ensure optimal health and coloration.
  • Sponge and algae-based supplements are essential for nutritional balance.

Habitat

  • Needs a spacious aquarium (minimum 180 gallons) with plenty of swimming space and live rock structures for territory and shelter.
  • Thrives best in a mature and stable aquarium environment.
  • Live rock structures providing hiding spaces and territories are essential.
  • Requires strong filtration and moderate water circulation for optimal health.

Fish Care

  • Ideal water temperature: 74-79°F (23-26°C).
  • Recommended pH: 8.1-8.4; specific gravity: 1.020-1.025.
  • Sensitive to poor water quality; regular water testing and frequent water changes necessary.
  • Prone to marine parasites; vigilant monitoring and proactive care are important.

Compatibility

  • Semi-aggressive; best housed with similarly sized and temperament-compatible fish.
  • Territorial towards other angelfish or similarly shaped and colored species.
  • Not reef-safe; likely to nip at corals, sponges, and ornamental invertebrates.
  • Suitable companions include large tangs, groupers, wrasses, and other robust marine species.

Aquarium Behavior

  • Active swimmer and displays assertive territorial behavior.
  • Juveniles are shy initially but become bolder and more assertive with age.
  • Often interactive, especially during feeding times, recognizing caretakers readily.
  • Providing adequate hiding places and enrichment can significantly reduce stress and aggression.
