Description

The Maroon Gold Nugget Clownfish displays a deep golden-yellow to true gold colouring across most of its body, often appearing metallic under reef lighting. As it matures, the gold coloration intensifies, becoming more uniform and lustrous. Fins are typically edged in white or lighter gold, and juveniles may show transitional patterns before developing full adult coloration.

Adults reach 13–15 cm (5–6 inches), making this one of the larger clownfish species. The strongly arched body, elongated fins, and prominent cheek spines (particularly in females) give the Gold Nugget a commanding and distinctive appearance.

Aquarium Requirements

Minimum Tank Size: 180 litres (50 US gallons)
(Larger recommended for pairs)

Temperature: 24–27 °C (75–81 °F)

pH: 8.1–8.4

Specific Gravity (Salinity): 1.023–1.025

Alkalinity: 8–12 dKH

Ammonia & Nitrite: 0 ppm

Nitrate: < 20 ppm

Aquascape and Environment:
Provide a mature aquarium with extensive rockwork and open swimming areas. As a larger, more territorial clownfish, the Maroon Gold Nugget appreciates having a clearly defined hosting area such as an anemone, large soft coral, or rock crevice. Stability, high water quality, and moderate flow are essential for long-term health.

Diet and Feeding

The Gold Nugget Maroon Clownfish is an omnivore and readily accepts a wide variety of prepared foods. A balanced, nutrient-rich diet supports vibrant coloration and overall vitality.

Recommended Foods:

• Frozen mysis shrimp, enriched brine shrimp, and chopped marine blends

• High-quality pellets and flakes for marine omnivores

• Supplemental algae- or spirulina-based foods

• Occasional live foods such as copepods or blackworms to stimulate natural feeding behaviour

Feed 1–2 times daily, with portions appropriate for its larger size.

Temperament and Compatibility

The Maroon Gold Nugget is known for being more territorial than other clownfish species, particularly as it reaches adulthood. Females are significantly larger and can be dominant. While highly rewarding to keep, it is best suited to aquarists familiar with managing semi-aggressive species.

Suitable Tankmates:

• Larger peaceful to moderately assertive fish such as tangs, dwarf angels, larger wrasses, and rabbitfish

• Reef-safe invertebrates such as snails and cleaner shrimp (caution with very small shrimp)

• A single bonded mate (pairing must be done carefully)

Avoid:

• Other clownfish species

• Small, timid fish that may be bullied

• Fish of similar shape or size that provoke territorial displays

• Very small ornamental shrimp in compact tanks

Reef Compatibility

✅ Reef Safe (with caution due to size and strength)

The Maroon Gold Nugget does not nip at corals or sessile invertebrates, making it reef safe. However, its size and strength mean it may rearrange loose coral frags or substrate while establishing a hosting area. It may naturally host:

• Bubble Tip Anemones (Entacmaea quadricolor)

• Large leather corals

• Euphyllia species (with caution due to vigorous hosting behaviour)

Additional Information

Maximum Size: 13–15 cm (5–6 inches)
Lifespan: 10–12+ years in captivity (with proper care)
Difficulty Level: Moderate (due to territorial behaviour and larger size)
Natural Behaviour: Strongly territorial; forms intense bonds with hosts; females exhibit cheek spines
Origin: Captive-bred designer variant
Colouration: Rich gold body with pale gold or white fin edges; coloration intensifies with age

Summary

The Aquacultured Maroon Gold Nugget Clownfish (Premnas biaculeatus) is a bold, visually stunning designer variant prized for its deep golden coloration and commanding presence. Hardy, reef safe, and highly expressive, it thrives in well-established aquariums with ample space, strong filtration, and carefully selected tankmates. Best suited for intermediate to advanced aquarists, this striking clownfish serves as a vibrant centrepiece, offering personality, beauty, and long-term aquarium enjoyment.
