General Information

The Golden Basslet, known scientifically as Gramma dejongi, is a rare and captivating species in the aquarium trade. This fish is renowned for its stunning golden-yellow coloration, which makes it a highly sought-after addition to any marine aquarium. First recognized as a new species by Arie de Jong in 2010, this fish is named in his honor due to his contributions to the aquarium trade. Gramma dejongi is native to the waters around Cuba, making it a unique and exotic choice for hobbyists.

Despite its beauty, the Golden Basslet is not commonly found in the aquarium trade due to its limited natural range and the challenges associated with its collection. This rarity contributes to its appeal among collectors and enthusiasts who are looking to add a truly special specimen to their tanks.

Care

The Golden Basslet is considered a moderately easy species to care for, making it suitable for aquarists with some experience. It thrives in well-established marine aquariums with plenty of live rock for hiding and exploring. A tank of at least 100 liters is recommended to provide ample space for swimming and territory establishment. Providing a variety of hiding spots and territories within the tank will help reduce stress and promote natural behaviors.

Diet and Feeding

In the wild, the Golden Basslet feeds on small invertebrates and zooplankton. In captivity, it should be offered a varied diet that includes high-quality marine pellets, frozen mysis shrimp, and brine shrimp. Feeding should occur once or twice daily, with portions that can be consumed within a few minutes.

Offering a diverse diet not only meets their nutritional needs but also enhances their vibrant coloration and overall health. Occasional supplementation with vitamins can further support their immune system.

Behavior and Compatibility

Gramma dejongi is generally peaceful, making it a good candidate for community tanks. However, it can be territorial towards its own kind or similar-looking species, so it is best kept singly or in a well-spaced tank if multiple individuals are desired.

This species is compatible with a variety of peaceful tank mates, including gobies, blennies, and other small reef-safe fish. Caution is advised when housing with larger or more aggressive species that may intimidate or outcompete them for food.

Reproduction

Captive breeding of the Golden Basslet has been attempted by a few aquarists and research facilities, but success has been limited. The challenges lie in replicating the precise environmental conditions and behaviors needed for breeding. Some success has been achieved with well-established breeding pairs, but overall, the species remains difficult to breed in captivity, contributing to its rarity in the aquarium trade. Continued efforts are being made to understand the breeding behaviors of this species better, with the hope of making captive-bred specimens more available in the future.

Health and Common Issues

The Golden Basslet can live for several years in captivity with proper care. Ensuring a stable environment and a balanced diet are key to their longevity. Regular monitoring of water quality and tank conditions is essential to prevent common health issues.

When selecting a Golden Basslet, look for active individuals with bright colors and no visible signs of disease. Routine care should include regular water changes and observation for any signs of stress or illness.

Habitat

Gramma dejongi is native to the coral reefs around Cuba, where it inhabits caves and crevices. These environments provide shelter and abundant food sources, contributing to their natural behavior and feeding habits. In the aquarium, replicating this habitat with live rock and appropriate hiding places will help them feel secure and exhibit natural behaviors.
