Goldflake Angelfish (Apolemichthys xanthopunctatus)
Overview
The Goldflake Angelfish (Apolemichthys xanthopunctatus) is a rare and visually stunning marine angelfish distinguished by its dark brown to black body adorned with bright golden-yellow spots, giving it a “goldflake” appearance. Its elegant, oval-shaped body and delicate fins make it a highly sought-after species in the marine aquarium hobby.
Native to the central Pacific, particularly around Fiji, Tonga, and the surrounding island reefs, this species inhabits outer reef slopes and lagoons, often among sponges and coral outcrops. Its rarity, combined with its specialized diet, makes it suitable only for experienced aquarists with large, well-established reef systems.
Aquarium Requirements
Minimum Tank Size: 450 litres (120 US gallons)
Temperature: 24–27 °C (75–81 °F)
pH: 8.1–8.4
Specific Gravity (Salinity): 1.020–1.025
Alkalinity: 8–12 dKH
Ammonia & Nitrite: 0 ppm
Nitrate: < 10 ppm
Aquascape:
Provide a mature aquarium with extensive live rock, caves, and crevices for grazing and refuge. Open swimming areas are important, but the Goldflake Angelfish appreciates hidden zones to reduce stress, especially during acclimation.
A well-oxygenated, stable environment with moderate water flow is essential for maintaining health and coloration.
Diet and Feeding
The Goldflake Angelfish is omnivorous with a strong preference for sponges. In captivity, its specialized diet makes it challenging to maintain.
Recommended Foods:
-
High-quality frozen angelfish diets enriched with sponge and algae
-
Spirulina- and algae-based flakes or pellets
-
Mysis shrimp, brine shrimp, finely chopped seafood (clam, scallop, squid)
-
Live rock grazing to stimulate natural feeding behavior
Feed 2–3 times daily in small portions. Nutritional supplementation with sponge-based foods is critical to prevent malnutrition and maintain vibrant coloration.
Temperament and Compatibility
The Goldflake Angelfish is peaceful but somewhat shy, particularly in newly established aquariums.
Suitable Tankmates:
-
Peaceful community fish such as tangs, butterflyfish, clownfish, and wrasses
-
Other angelfish species only in very large tanks to avoid territorial disputes
Avoid:
-
Aggressive or highly territorial species that may stress this delicate angelfish
-
Rapidly growing predatory fish
Juveniles are often reclusive and may hide frequently, while adults gradually become more confident in a well-structured environment.
Reef Compatibility
✅ Generally Reef Safe (with caution)
The Goldflake Angelfish is mostly reef compatible, rarely harming corals or sessile invertebrates when provided with adequate nutrition. However, due to its natural preference for sponges, supplementation is necessary to prevent opportunistic coral nipping.
Best Practices:
-
Introduce into a mature reef with plenty of live rock
-
Offer sponge-rich prepared foods and frozen diets
-
Monitor for occasional nibbling on sessile invertebrates if dietary needs are unmet
Additional Information
Maximum Size: 20–25 cm (8–10 inches)
Lifespan: 10–15 years with proper care
Difficulty Level: Advanced
Natural Behavior: Peaceful, shy, primarily mid-water to reef slope grazer; becomes more confident as it acclimates
Origin: Central Pacific – Fiji, Tonga, and surrounding islands
Coloration: Dark body with numerous bright gold spots, often more pronounced in adults
Summary
The Goldflake Angelfish (Apolemichthys xanthopunctatus) is a rare and captivating reef angelfish, ideal for experienced aquarists with large, mature reef systems. Its striking coloration, peaceful temperament, and grazing behavior make it a visually stunning addition, but its dietary specialization and sensitivity require attentive care. With stable water conditions, proper nutrition, and ample live rock, the Goldflake Angelfish can thrive for over a decade, maintaining vibrant colors and natural behaviors.
