Pomacanthus sexstriatus - Sixbar Angelfish

Pomacanthus sexstriatus (Sixbar Angelfish)

Overview

  • Native to the Indo-West Pacific, commonly found around coral-rich reefs and lagoons.
  • Recognizable by its distinctive body marked with vertical black bars over a pale background, and vibrant blue highlights on fins.
  • Known for a bold, territorial personality, making it suitable for experienced aquarists.
  • Requires careful management due to its aggressive tendencies and specialized habitat needs.

Feeding

  • Omnivorous diet, naturally consuming sponges, algae, tunicates, coral polyps, and small invertebrates.
  • In captivity, provide a diverse diet including marine algae sheets, sponge-based foods, mysis shrimp, brine shrimp, and chopped seafood.
  • Frequent daily feedings are essential to maintain health, coloration, and activity.
  • Dietary supplements with algae and sponges recommended for nutritional completeness.

Habitat

  • Requires large aquariums (minimum 180 gallons) with ample swimming space and structured live rock formations.
  • Stable and mature aquarium conditions are critical for long-term health.
  • Plenty of caves and hiding spots needed to replicate their natural reef environments and reduce stress.
  • Strong filtration and moderate water circulation are necessary for optimal water quality.

Fish Care

  • Preferred water temperature: 74-79°F (23-26°C).
  • Recommended pH level: 8.1-8.4; specific gravity: 1.020-1.025.
  • Sensitive to fluctuations in water parameters; regular monitoring and careful maintenance essential.
  • Vigilant observation for marine diseases and parasites; early intervention crucial for successful care.

Compatibility

  • Semi-aggressive; best housed with similarly sized, temperament-compatible species.
  • Not reef-safe; tends to nip at corals, sponges, and ornamental invertebrates.
  • Suitable tank mates include larger tangs, wrasses, and other semi-aggressive marine species.
  • Territorial behavior requires ample space and careful management to prevent conflicts.

Aquarium Behavior

  • Bold and territorial, actively patrolling and defending territory.
  • May initially be shy as juveniles but become assertive and interactive as they mature.
  • Engages actively with caretakers, particularly at feeding times.
  • Providing ample hiding spaces and clear territory boundaries helps manage aggression and stress.
