Description

Scientific Name: The Gold Nugget Wrasse is scientifically known as Xenojulis margaritaceus. It is also sometimes referred to as the Finspot Wrasse or Pearl Wrasse.

Appearance:

• They have a tan to orange body adorned with numerous small, bright spots that resemble gold nuggets.  
• Some males, known as "super males," can exhibit a metallic green coloration with red spots.  
• They have a streamlined body shape typical of wrasses.

Size:

• Gold Nugget Wrasses are relatively small, reaching a maximum size of around 4-5 inches (10-12 cm).  

Tank Requirements:

• A minimum tank size of 50-55 gallons (around 200 liters) is recommended due to their active nature and need for swimming space.  
• They require a deep sand bed (several inches) as they bury themselves in the sand to sleep at night or when feeling threatened.  
• Plenty of live rock is essential to provide hiding places and promote natural behaviors. A tight-fitting lid is crucial as they are known to jump.  

Water Parameters:

• Temperature: 72-78°F (22-26°C)  
• Salinity: 1.020-1.025 specific gravity (sg)  
• pH: 8.1-8.4  
• Alkalinity: 8-12 dKH  
• Nitrate: Ideally 0 ppm, or as low as possible  

Temperament:

• Generally considered peaceful and can be a good addition to a community reef tank.  
• However, they can be semi-aggressive towards other wrasses, especially those with similar body shapes or colors. It's best to introduce them simultaneously or avoid housing them with closely related species.
• They may nip at small, delicate invertebrates, so caution is advised when keeping them in a reef tank with such creatures. Larger, more robust invertebrates are usually safe.  

Diet:

• Gold Nugget Wrasses are carnivores.  
• Their diet should consist of high-quality frozen or live meaty foods, such as:
  • Mysis shrimp  
  • Brine shrimp
  • Finely chopped seafood

Reef Compatibility:

• Generally considered reef safe, but they may prey on small crustaceans and worms. Exercise caution when housing them with prized or delicate invertebrates.

Care Level:

• Considered moderate due to their specific needs, such as a deep sand bed and appropriate tank mates.

Tank Mates:

• Good tank mates include other peaceful to semi-aggressive fish that won't bother them. Consider:  
  • Small gobies
  • Blennies
  • Dartfish
  • Other peaceful wrasses (with caution and proper planning)
• Avoid housing them with aggressive fish that may intimidate or harm them.
