Hybrid Achilles White Cheek Tang

Hybrid Achilles White Cheek Tang

Also known as Hybrid Achilles Tang or Hybrid Whitecheek Surgeonfish.
The Hybrid Achilles White Cheek Tang is a visually striking tang featuring a dark body with bold white cheek patches and the signature orange-red “Achilles” tail markings. This hybrid tang combines traits from its parent species, offering a unique coloration pattern and dynamic presence in reef aquariums. Hardy and active, it is suitable for intermediate to advanced aquarists who can provide ample swimming space and stable water conditions. Captive-bred specimens adapt well to aquarium life and are a vibrant addition to both FOWLR and reef setups.

Habitat & Tank Requirements

Natural Habitat: As a hybrid, it is primarily maintained in captivity. Parent species inhabit coral-rich reefs, lagoons, and seaward slopes in the Indo-Pacific. The hybrid thrives in similar environments with moderate water flow and ample algae grazing surfaces.

Tank Environment:

• Open swimming space essential for active behavior
• Moderate water flow to mimic natural currents
• Plenty of live rock for grazing and hiding
• Secure lid to prevent jumping
• Established aquariums recommended (3+ months)

Water Parameters:

• Temperature: 74–82°F (23–28°C)
• Salinity: 1.023–1.025 specific gravity
• pH: 8.1–8.4
• Ammonia/Nitrite: 0 ppm
• Nitrate: <20 ppm
• Alkalinity: 8–12 dKH

Essential Equipment:

• Efficient protein skimmer
• Strong filtration system
• Stable lighting suitable for reef or FOWLR setups
• Regular water changes (10–15% weekly)

Diet & Feeding

Hybrid Achilles White Cheek Tangs are primarily herbivorous but will readily accept prepared foods once acclimated.

Recommended Foods:

• Pellets/Flakes: Algae-based, spirulina, herbivore formulas
• Frozen Foods: Finely chopped marine algae, phytoplankton
• Plant Matter: Nori sheets, spirulina sheets
• Prepared Mixes: Herbivore blends, enriched frozen preparations

Feeding Schedule:

• Feed 2–3 times daily
• Offer portions they can consume in 2–3 minutes
• Variety ensures healthy digestion and vibrant coloration

Behavior & Compatibility

Temperament: Semi-aggressive; may defend territory but generally peaceful with most species

Tank Mates: Compatible with most peaceful reef fish including gobies, wrasses, blennies, and non-aggressive tangs. Caution with aggressive tangs or predatory species.

Pairing Behavior: Can be kept singly or in groups in large aquariums. Juveniles adapt more readily to community environments.

Reef Compatibility

• Completely reef-safe; will not harm corals or invertebrates
• Suitable for mixed reef or FOWLR aquariums

Acclimation & Care Tips

Initial Acclimation:

• Drip acclimation over 45–60 minutes
• Float bag for temperature equalization (15–20 minutes)
• Dim lights during introduction

Health Considerations:

• Susceptible to marine ich (Cryptocaryon) if stressed
• Quarantine for 2–3 weeks before adding to display tank

Signs of a Healthy Specimen:

• Active swimming and grazing
• Clear eyes and smooth fins
• Vibrant dark body with bright white cheek patches and orange-red tail

Color & Development

Coloration Characteristics:

• Body: Dark gray to black
• Cheeks: Bold white patches
• Tail: Orange-red “Achilles” marking
• Eyes: Clear and bright

Color Intensity:

• High-quality diet maintains vivid coloration
• Proper lighting enhances contrast
• Stress or poor water quality may cause temporary fading

Size & Growth:

• Juveniles start at 3–4 inches
• Reach adult size (9–12 inches) within 12–18 months

Special Considerations

Quarantine is Recommended: Observed for parasites and disease, monitored for appetite and activity, conditioned to prepared aquarium foods.

Captive-Bred Advantages:

• Better adaptation to aquarium life
• Reduced disease risk
• More consistent coloration
• Stronger feeding habits

Breeding Potential:

Breeding hybrids in captivity is extremely rare and not typically documented. Observing natural behavior and optimal conditions can provide enrichment for the fish but spawning is unlikely in standard aquariums.

Why Choose a Quarantined Hybrid Achilles White Cheek Tang?

A fully quarantined Hybrid Achilles White Cheek Tang ensures better long-term success, fewer health issues, and a smoother transition into your display tank. Captive-bred, healthy specimens showcase striking coloration and active behavior, making them a vibrant centerpiece in your reef or FOWLR aquarium.
