Scopas Tang

Also known as the Brown Scopas Tang or Scopas Surgeonfish.
The Scopas Tang is a peaceful, medium-sized tang with a subtle brown to olive coloration and oval-shaped body. Native to the Indo-Pacific, this species is popular among reef hobbyists for its calm temperament, grazing habits, and adaptability. Its understated appearance contrasts beautifully in reef aquariums, providing a natural, soothing presence while helping to control algae growth.

Habitat & Tank Requirements

Natural Habitat:
Found on coral-rich, lagoon, and reef slope areas of the Indo-Pacific, including the Red Sea, East Africa, and Pacific islands. They thrive in moderate currents with abundant grazing opportunities.

Tank Environment:

•  Moderate water flow with open swimming space
•  Plenty of live rock for grazing and hiding
•  Stable water parameters with high oxygen levels
•  UV sterilizer recommended to reduce parasite exposure

Water Parameters:

• Temperature: 74–80°F (23–27°C)
• Salinity: 1.023–1.025
• pH: 8.1–8.4
• Ammonia/Nitrite: 0 ppm
• Nitrate: <10 ppm
• Alkalinity: 8–12 dKH

Essential Equipment:

• Oversized protein skimmer
• Moderate circulation pumps
• UV sterilizer for parasite prevention
• Auto-top-off system for water stability
• Regular water changes (15–20% weekly)

Diet & Feeding

Scopas Tangs are primarily herbivorous and graze constantly on algae. They require a varied diet to maintain health and vibrant coloration.

Recommended Foods:

• Nori sheets (green, red, brown)
• Spirulina-based flakes or pellets
• Frozen herbivore blends
• Occasional mysis or brine shrimp for variety
• Vitamin-enriched foods for immune support

Feeding Schedule:

• Feed 2–3 times daily
• Provide continuous access to algae or nori
• Rotate food types for balanced nutrition

Behavior & Compatibility

Scopas Tangs are generally peaceful but may be territorial toward other tangs of similar size or shape. They are calm swimmers and adapt well to community reef aquariums once acclimated.

Tank Mates:

• Compatible with: peaceful community fish, gobies, blennies, wrasses, anthias, and most reef-safe species
• Caution with: other tangs in small tanks, semi-aggressive tangs
• Avoid: very aggressive triggers or overcrowding of surgeonfish

Color & Development
Scopas Tangs have a subtle brown to olive body with lighter underbellies. Juveniles may display more vivid coloration with faint stripes, gradually fading as they mature. Under optimal lighting and diet, they maintain a healthy sheen and smooth gradient tones.

Size & Growth:
Juveniles are typically 2–3 inches and grow steadily to 7–9 inches as adults.

Acclimation & Care Tips

Initial Acclimation:

• Drip acclimate for 45–60 minutes
• Float bag for temperature equalization
• Dim lights during introduction
• Provide immediate access to algae and hiding areas
• Avoid adding to new or unstable tanks

Health Considerations:
Scopas Tangs can be prone to marine ich (Cryptocaryon) and HLLE if diet or environment is poor.

Signs of a Healthy Specimen:

• Active swimming and grazing behavior
• Clear eyes and smooth fins
• Strong appetite and healthy coloration
• No flashing or labored breathing

Special Considerations

Quarantine is Recommended:
Quarantined Scopas Tangs have higher survival rates, are conditioned to prepared foods, and are free from parasites. Dr Reef’s quarantine protocol ensures each fish is:

• Observed and treated preventatively
• Conditioned to aquarium diet
• Stabilized before shipment

Breeding Potential

Breeding Scopas Tangs in home aquariums is extremely rare due to their territorial and schooling nature. Most breeding behavior is observed only in large, stable reef systems.

Why Choose a Quarantined Scopas Tang?

Quarantined Scopas Tangs are healthier, settle faster, and adapt more readily to aquarium life. This ensures long-term success and a stress-free experience for hobbyists while maintaining the fish’s natural coloration and behavior.
