• Maximum Size: Can grow up to 12 to 14 inches (30 to 36 cm) in length.
• Lifespan: In the wild, they can live between 25 and 30 years; in captivity, they typically live up to 10 years with proper care.
• Level of Difficulty: Moderate to difficult; requires a large, well-maintained aquarium and stable water conditions.

Appearance & Physical Traits:

• Coloration & Pattern: Vibrant yellow body with blue and black horizontal stripes running from head to tail. Juveniles have a more pronounced blue coloration, which fades as they mature.
• Body Shape & Structure: Streamlined, elongated body with a laterally compressed profile, typical of surgeonfish. Equipped with sharp spines on both sides of the tail base, used for defense.

Habitat & Environmental Needs:

• Minimum Tank Size: Requires a minimum tank size of 250 gallons (946 liters) to accommodate its size and active swimming behavior.
• Water Temperature: Maintain between 75°F and 82°F (24°C to 28°C).
• pH Level: Keep between 8.1 and 8.4.
• Specific Gravity: Optimal range is 1.020 to 1.025.
• Aquascape: Provide ample open swimming space with live rock structures for grazing and hiding. Ensure strong water movement to mimic natural reef currents.
• Tank Cover: Ensure the tank is securely covered, as this species may jump if startled.

Diet & Feeding:

• Diet Type: Omnivorous.
• Preferred Foods: A balanced diet including high-quality marine flakes or pellets, supplemented with algae, nori, and occasional meaty foods like mysis shrimp.
• Feeding Frequency: Feed 2 to 3 times daily, offering small portions to prevent overfeeding.

Behavior & Compatibility:

• Temperament: Semi-aggressive; can be territorial, especially towards other tangs or similarly shaped fish.
• Social Behavior: Active swimmer, often patrolling its territory.
• Tank Mate Compatibility: Best kept with other peaceful fish; avoid housing with aggressive species or other tangs to prevent territorial disputes.
• Activity Level: High; requires a spacious tank to accommodate its active nature.

Care Considerations & Additional Notes:

• Ease of Care: Moderate to difficult; requires a large, stable environment with consistent water parameters.
• Special Requirements: Regular water changes and high-quality filtration are essential. Provide a varied diet to ensure nutritional balance.
• Pest Control Benefits: While not a primary pest controller, it may help in maintaining a clean substrate by consuming small invertebrates.
• Additional Notes: Due to its size and specific care requirements, the Clown Surgeonfish is best suited for experienced hobbyists with appropriately sized tanks. Regular monitoring of water quality and fish health is crucial for its well-being.
