General Description: The Black Longnose Tang, also known as the Longnose Tang or Black Sailfin Tang, is found only in Hawaii and the Christmas Islands. Perhaps one of the most ubiquitous saltwater fishes, the Black longnose tang has a typical Zebrasoma body shape that is entirely jet black in color. Some specimens have been observed with a greenish-silver streak along the forehead and base of the dorsal fin, but this could be attributed to differences in collection areas, age, or both. This tang is found inhabiting reefs off the shores of some of the most remote islands in the world, making their availability somewhat rare. As a result of this limited access, the Black longnose tang has a high price tag. Despite this cost, the Black longnose tang is a relatively hardy and easy species to care for much like the other Zebrasoma tangs. An adult Black longnose tang can reach a size of approximately 9″. Note: With the closure of Hawaiian fisheries in 2020, Black longnose tangs are only available from the Christmas Islands.
Diet Requirements: In the wild tangs are primarily herbivorous. A diet largely consisting of algae-based foods is absolutely necessary to maintain optimal health, coloration, immune function, and reduce aggression. If not, tangs often develop head and lateral line erosion from such deficiencies. Vegetable based flake foods or frozen foods, that may also include spirulina algae, are excellent options. We also recommend offering dried seaweed on a rock or clip three times a week minimum. Black longnose tangs will consume various other protein-based frozen foods.
Care Requirements: An established minimum 200 gallon aquarium with 18+ inch width is ideal. Juvenile specimens can be temporarily raised in smaller quarters (no less than 120 gallons) as long as it is upgraded accordingly. This tang enjoys a variety of rock work and crevices to take refuge, but also should be provided with ample open swimming space. Black longnose tangs are often sought after to add to a reef aquarium for not only their appearance, but their natural tendency to graze upon algae build up. Typically, Zebrasoma species are semi-aggressive and territorial in nature. If you are looking to avoid potential rough-housing with other tank-mates, it can help to introduce this fish last. Additionally, Zebrasoma often conflict with other tang species or fish that have a similar body shape. If you want to house multiple types of tangs together, it is best to add them all at once, or closely together at the very least, for the best success.
