Pomacanthus navarchus - Majestic Angelfish

Pomacanthus navarchus (Majestic Angelfish)

Overview

  • Native to the Indo-Pacific region, commonly inhabiting coral reefs, lagoons, and reef slopes.
  • Known as the Majestic Angelfish, recognized for its striking blue and yellow-orange coloration with intricate patterns.
  • Juveniles have distinct black bodies with vertical blue and white stripes that transition dramatically as they mature.
  • Has a relatively shy yet bold personality, requiring proper acclimation to thrive in captivity.

Feeding

  • Omnivorous; diet consists of sponges, tunicates, algae, and small invertebrates.
  • Readily accepts varied foods including specialized angelfish diets, marine algae sheets, mysis shrimp, brine shrimp, and chopped seafood.
  • Frequent daily feedings recommended to sustain optimal health and vibrant coloration.
  • Incorporate algae and sponge-based supplements to maintain nutritional balance.

Habitat

  • Requires a spacious aquarium (minimum 150 gallons) with ample swimming space and structured live rock formations.
  • A mature, stable aquarium environment is essential for long-term success.
  • Include numerous hiding spaces and caves in rockwork to minimize stress and territorial aggression.
  • Maintain strong filtration and moderate water circulation for optimal water quality.

Fish Care

  • Preferred water temperature: 74-80°F (23-27°C).
  • Recommended pH: 8.1-8.4; specific gravity: 1.020-1.025.
  • Sensitive to poor water conditions; regular testing and water changes are crucial.
  • Monitor closely for marine parasites and infections, promptly addressing any health concerns.

Compatibility

  • Semi-aggressive species; best kept with similar-sized fish that have compatible temperaments.
  • Can become territorial, especially toward other angelfish or similarly colored species.
  • Not reef-safe; known to nip at corals, sponges, and ornamental invertebrates.
  • Suitable tank mates include larger tangs, wrasses, groupers, and other semi-aggressive marine species.

Aquarium Behavior

  • Initially shy but becomes a bold and active swimmer once acclimated.
  • Juveniles tend to hide more often; adults grow increasingly confident over time.
  • Often interacts positively with caretakers, especially during feeding times.
  • Providing adequate hiding places and enrichment significantly reduces stress and aggressive behavior.
