• Be aware of: Requires deep-water conditions; needs ample hiding spots; may exhibit territorial behavior

 

Appearance and Coloration

The Golden Basslet is celebrated for its vibrant and striking coloration. Its body exhibits a brilliant combination of saturated yolk-yellow blending into rich tangerine hues toward the center. The transition zone between these colors features a honeycomb-like reticulated pattern, especially prominent near the dorsal region. This vivid coloration makes the Golden Basslet a highly sought-after species among marine aquarists. 

 

Natural Habitat and Behaviour

Liopropoma aberrans is native to the Western Central Atlantic, with occurrences reported from Cuba, Curaçao, and the Gulf of Mexico. This species inhabits deep reef environments, typically found at depths ranging from 300 to 500 feet (approximately 90 to 150 meters). Due to its deep-water habitat, the Golden Basslet is less commonly encountered and is considered a rare find in the aquarium trade. 

In the wild, the Golden Basslet exhibits reclusive behavior, often seeking shelter among rocky crevices and overhangs within the reef structure. It is generally solitary and may display territorial tendencies, especially when space is limited.

 

Tank Requirements and Water Parameters

• Minimum Tank Size: 280 liters (75 gallons)

• Water Parameters:

• Temperature: 20°C (68°F)

• pH: 8.1 – 8.4

• Specific Gravity: 1.020 – 1.025

• Aquascaping:

• Incorporate ample live rock formations to provide hiding spots and establish territories.

• Ensure the presence of caves and crevices to mimic natural habitats.

• Lighting: Moderate to low; subdued lighting replicates their deep-water environment and helps reduce stress.

• Water Movement: Moderate flow, simulating natural reef currents.

 

Diet and Feeding

In their natural environment, Golden Basslets primarily consume small fish and crustaceans. In captivity:

• Captive Diet:

• Offer a variety of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood.

• High-quality frozen or live foods can help maintain vibrant coloration and health.

• Feeding Frequency: Once or twice daily, ensuring portions are appropriate to prevent overfeeding.

Compatibility and Social Structure

• Temperament:

• Generally peaceful, making them suitable for community tanks.

• May exhibit territorial behavior toward conspecifics or similar species; best kept singly unless in a large aquarium with ample hiding spots.

• Tank Mates:

• Compatible with other peaceful fish such as gobies, blennies, and small wrasses.

• Caution with housing alongside ornamental shrimp or very small fish, as they may be perceived as prey.

• Avoid aggressive species that may intimidate or outcompete them.

• Reef Compatibility: Reef-safe; does not harm corals but may prey on small ornamental crustaceans.

 

Important Considerations

• Acclimation: Due to their deep-water origins, a slow acclimation process is recommended to help them adjust to captive conditions.

• Hiding Spots: Providing ample hiding places will help reduce stress and allow the fish to exhibit natural behaviors.

• Lighting: Prefers dimly lit environments; intense lighting may cause stress or reclusive behavior.

• Feeding Habits: May be shy feeders initially; offering live foods can encourage feeding responses during acclimation.
