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 atan to orange body adorned with numerous small,bright spots that resemble gold nuggets.
Some males, known as "super males," can exhibit ametallic green coloration withred spots.
They have a streamlined body shape typical of wrasses.
Size:
Gold Nugget Wrasses are relatively small, reaching a maximum size of around4-5 inches (10-12 cm).
Tank Requirements:
A minimum tank size of50-55 gallons (around 200 liters) is recommended due to their active nature and need for swimming space.
They require adeep sand bed (several inches) as they bury themselves in the sand to sleep at night or when feeling threatened.
Plenty oflive 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 consideredpeaceful 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 atsmall, 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 arecarnivores.
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.
