Yellow-Backed Damsel

The Yellow-Backed Damsel (Paraglyphidodon melas) is a captivating marine fish known for its striking coloration and active behavior. This species exhibits a bright yellow dorsal region that sharply contrasts with its deep blue body, making it a standout in any reef aquarium. As a member of the Pomacentridae family, it showcases the diverse beauty found within the coral reefs of the Indo-Pacific region.

In its natural habitat, the Yellow-Backed Damsel thrives among coral structures, where it establishes territories and engages in dynamic social interactions. Typically found at depths of 1 to 30 meters, this species prefers areas with abundant coral cover, which provides both shelter and breeding grounds. The Yellow-Backed Damsel is known for its aggressive nature, particularly during breeding seasons, where males display vibrant colors to attract females and defend their nests.

Behaviorally, these fish are highly social and can often be seen in small groups or harems. They exhibit territoriality, especially males, who are known to chase away intruders from their chosen territory. Their active swimming style and curious nature make them a delight to observe, contributing to their popularity in the aquarium trade.

The Yellow-Backed Damsel is not only visually appealing but also plays a crucial role in the health of coral reef ecosystems. By grazing on algae and detritus, they help maintain the balance within their environment, showcasing their importance beyond the aquarium setting.

To successfully care for the Yellow-Backed Damsel, maintain water parameters within a range of 24-28°C and a salinity of 1.020-1.025 ppt. A pH level between 8.1-8.4 is optimal for their health. These fish thrive in well-established aquariums of at least 100 liters, providing ample swimming space and hiding spots.

Feeding should consist of a varied diet, including high-quality flake or pellet foods, supplemented with frozen or live foods such as brine shrimp and mysis shrimp to ensure proper nutrition. Compatibility is generally good, but caution is advised when introducing them to smaller or more docile species, as they can be territorial.

Acclimation is crucial; use a slow drip method to ease them into the new environment over several hours. A quarantine period of at least two weeks is recommended before introducing them to the main tank to prevent the spread of diseases. Regular monitoring of water quality will help maintain a healthy environment for these dynamic fish.

The Yellow-Backed Damsel is suitable for shipping due to its hardy nature, but it's important to pack them securely to minimize stress. A recommended packing density is 1 fish per 1.5 liters of water to ensure adequate space during transit. They are moderately temperature-sensitive, so maintaining a stable shipping temperature of 24-26°C is essential. This species is not listed under CITES, simplifying the export process.
