Dascyllus melanurus, commonly known as the Blacktail Damselfish, is a popular choice among marine aquarium enthusiasts due to its striking appearance and robust nature. This species displays a distinctive black tail contrasted against a white body with black markings, making it a visually appealing addition to reef or fish-only tanks.
Care Level: Dascyllus melanurus is considered hardy and suitable for both beginner and experienced aquarists. It adapts well to captive conditions when provided with appropriate care.
Temperament: This damselfish is moderately territorial and can exhibit aggression, especially in smaller tanks or when kept singly. It is best housed with other semi-aggressive or robust species. Avoid pairing with very peaceful or slow-moving fish to reduce stress.
Diet: Omnivorous by nature, Dascyllus melanurus thrives on a varied diet including high-quality marine flakes, pellets, frozen mysis shrimp, brine shrimp, and finely chopped seafood. Regular feeding 1-2 times daily is recommended.
Minimum Tank Size: A minimum of 75 litres (20 gallons) is advised to provide sufficient swimming space and to help manage territorial behaviour.
Lighting and Water Flow: Standard reef aquarium lighting and moderate water flow suit this species well. They do not have special lighting requirements but appreciate a well-oxygenated environment.
Placement: Provide plenty of live rock or artificial structures to create hiding spots and territories. This helps reduce aggression and encourages natural behaviour.
Origin: Native to the Indo-Pacific region, including areas around the Philippines and Indonesia.
Maximum Size: Typically grows up to 8 cm (3 inches) in length.
Dascyllus melanurus is a resilient and visually striking damselfish that can add dynamic movement and interest to your marine aquarium. When housed in appropriate conditions with compatible tank mates, it can thrive and display its natural behaviours.
