Overview
- Native to the Indo-Pacific region, commonly found around coral reefs and lagoon environments.
- Known for its vibrant blue-green body with distinctive semicircular patterns and intricate blue markings on the fins.
- Juveniles have bold blue, black, and white semicircular bands which evolve dramatically into adult coloration.
- Displays a confident and somewhat territorial behavior, suitable for experienced marine aquarists.
Feeding
- Omnivorous; naturally consumes sponges, algae, tunicates, and small marine invertebrates.
- Accepts various aquarium foods including marine algae, angelfish-specific preparations, mysis shrimp, brine shrimp, and chopped seafood.
- Feed multiple times daily to sustain optimal health and vibrant coloration.
- Essential dietary supplements include algae-based and sponge-based foods for balanced nutrition.
Habitat
- Requires a large aquarium (minimum 180 gallons) with ample swimming room and well-structured live rock.
- Mature, stable aquarium conditions are essential for long-term health.
- Provide numerous hiding spots and caves in rockwork to reduce stress and aggression.
- Efficient filtration and moderate to strong water circulation necessary to maintain 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 conditions; consistent water testing and regular water changes required.
- Monitor carefully for signs of marine parasites and diseases; proactive management is crucial.
Compatibility
- Semi-aggressive; suitable tank mates include similarly sized and tempered fish.
- Can become territorial towards other angelfish or similarly colored and shaped species.
- Not reef-safe; known to nip at corals, sponges, and decorative invertebrates.
- Recommended companions include tangs, larger wrasses, groupers, and other semi-aggressive marine species.
Aquarium Behavior
- Bold, active swimmer frequently exploring the aquarium.
- Juveniles often hide initially but become increasingly visible and assertive as they mature.
- Interactive with caretakers, especially during feeding sessions.
- Providing ample hiding spaces and environmental enrichment significantly reduces aggression and stress.
