Common name: Longtail Dottyback

General Information

The Longtail Dottyback, scientifically known as Oxycercichthys veliferus, is a striking species known for its elongated tail and vibrant coloration. This species is a relatively rare find in the aquarium trade, making it a prized addition for enthusiasts seeking something unique. Its vivid colors and active nature make it a captivating presence in any marine setup.

Despite its beauty, the Longtail Dottyback is not as commonly kept as other dottyback species, partly due to its limited availability and specific care requirements. However, for those willing to meet its needs, it offers an engaging and rewarding experience.

Care

The Longtail Dottyback requires a well-maintained aquarium with plenty of hiding spots, as it can be shy and territorial. A tank with live rock and crevices will help it feel secure. It thrives in stable water conditions, and maintaining good water quality is crucial for its health.

This species can adapt to a variety of foods, but a diet rich in marine proteins such as mysis shrimp, brine shrimp, and high-quality pellets is recommended. Regular feeding and a balanced diet will ensure its vibrant colors and overall well-being.

Diet and Feeding

In the wild, the Longtail Dottyback is a carnivore, feeding on small invertebrates and zooplankton. In captivity, it should be offered a varied diet including frozen or live foods like mysis shrimp and brine shrimp, along with quality marine pellets.

Feed this species once or twice daily, providing only as much food as it can consume in a few minutes to prevent overfeeding and maintain water quality.

Behavior and Compatibility

The Longtail Dottyback is known for its semi-aggressive temperament, particularly towards conspecifics and similarly shaped fish. It is best kept singly or in a large tank with plenty of hiding spots to mitigate territorial behavior.

While it can coexist with a variety of tank mates, caution should be exercised when housing it with other aggressive or territorial species. It is generally reef-safe but may pose a threat to small invertebrates.

Reproduction

Breeding the Longtail Dottyback in captivity is challenging, with few successful reports. They are egg-layers, and providing a suitable breeding environment with stable conditions is essential for any breeding attempts.

Health and Common Issues

The Longtail Dottyback is generally hardy but can be susceptible to common marine diseases such as ich. Maintaining optimal water quality and a stress-free environment is key to preventing health issues.

When selecting a Longtail Dottyback, look for active, alert individuals with vibrant colors and smooth fins. Avoid fish that appear lethargic or have visible signs of disease.

Habitat

Naturally found in the coral reefs of the Indo-Pacific region, the Longtail Dottyback prefers environments with plenty of hiding spots and stable water conditions. It thrives in warm, shallow waters with moderate flow, mimicking its natural habitat.
