The Naso Tang, scientifically known as Naso lituratus, is a popular marine fish in the aquarium hobby. It’s commonly called the “Lipstick Tang” or “Orangespine Unicornfish” due to its distinct coloration and markings, particularly the mature males’ extended rostrum (or “horn”) and the orange “lipstick” marking on its mouth.
Appearance: The Naso Tang is gray to brownish in its main body coloration, with blue striping on the dorsal and pectoral fins. Mature males will develop streamers from the tail, bright blue around their eyes, and the aforementioned extended rostrum (though it doesn’t always develop to the degree seen in the wild). The “lipstick” marking on the mouth is another defining feature.
Habitat: In the wild, they are found throughout the Indo-Pacific region, spanning from East Africa to the Hawaiian Islands.
Aquarium Care:
- Tank Size: Naso Tangs are active swimmers and grow relatively large (up to 18 inches/45 cm in the wild, though typically smaller in captivity). A tank of at least 180 gallons (680 liters) is recommended for a mature Naso Tang, with more space being even better.
- Diet: They are primarily herbivores. In the aquarium, they should be provided with a steady diet of marine-based seaweed and algae. Offer dried seaweed tied to a rock or use a veggie clip. Supplement their diet with occasional meaty foods, but greens should make up the majority of their intake.
- Tank Mates: Generally peaceful, Naso Tangs can be kept with a variety of other reef-safe species. However, they may show aggression toward other tangs, especially of the same species. To reduce the risk of territorial disputes, introduce tangs simultaneously if possible.
- Environment: A reef or FOWLR (Fish Only With Live Rock) setup works well. They need plenty of swimming space and also some hideouts among rocks or corals.
- Water Parameters: Typical marine conditions are required – salinity around 1.023-1.025 specific gravity, temperatures of 76-80°F (24-27°C), and pH between 8.1-8.4.
- Health: Like other tangs, Naso Tangs can be susceptible to marine ich and other common saltwater fish diseases. Quarantine new fish and maintain excellent water quality to reduce the risk of disease.
Conclusion: The Naso Tang is a striking and active marine fish, suitable for larger aquariums where it can display its natural behaviors. As with all marine species, thorough research and proper care will ensure that this tang remains a vibrant and healthy member of the aquarium community for many years.
