Pomacanthus maculosus (Yellowbar Angelfish)

Overview

  • Native to the Red Sea, Persian Gulf, and northwestern Indian Ocean, typically found around coral reefs and rocky outcrops.
  • Distinguished by its deep blue body, vibrant yellow vertical bar in the center, and blue-margined fins and tail.
  • Juveniles display black bodies with vertical blue and white stripes that transition as they mature.
  • Noted for its bold personality and territorial behavior in aquarium settings.

Feeding

  • Omnivorous diet; naturally feeds on algae, sponges, tunicates, and various invertebrates.
  • Readily accepts a variety of aquarium foods including angelfish diets, marine algae, frozen shrimp, mysis shrimp, brine shrimp, and chopped seafood.
  • Multiple feedings per day recommended to maintain health and vibrant coloration.
  • Dietary supplements containing algae and sponge are crucial for optimal nutrition.

Habitat

  • Requires a spacious aquarium (minimum 180 gallons) with ample swimming space and structured live rock formations.
  • Stable, mature aquarium environment is vital for their long-term health.
  • Ample hiding spots and territorial areas within the live rock structure recommended.
  • Strong filtration and moderate water circulation help maintain ideal water quality.

Fish Care

  • Optimal water temperature: 74-80°F (23-27°C).
  • Recommended pH: 8.1-8.4, specific gravity: 1.020-1.025.
  • Sensitive to poor water quality; routine testing and regular water changes essential.
  • Susceptible to marine parasites; consistent monitoring and prompt treatment important.

Compatibility

  • Semi-aggressive temperament; best kept with similarly sized and temperament-compatible fish.
  • Can be territorial, particularly towards other angelfish or similar-shaped species.
  • Generally not reef-safe; prone to nip at corals, sponges, and ornamental invertebrates.
  • Ideal tank mates include large tangs, groupers, wrasses, and other semi-aggressive marine species.

Aquarium Behavior

  • Active, bold swimmers often seen exploring and patrolling their territory.
  • Juveniles are initially shy, becoming increasingly assertive and visible as adults.
  • Known to interact positively with caretakers, especially during feeding times.
  • Providing adequate hiding spaces and environmental enrichment reduces aggression and stress.
