Naso brevirostris, commonly known as the Spotted Unicorn Tang or Short-nosed Unicornfish, is a captivating medium-sized tang that adds elegance and movement to large marine aquariums. Recognisable by its elongated body and distinctive snout, this species is a peaceful herbivore that thrives in well-established reef or fish-only systems.
Care Level: Moderate – suitable for aquarists with some marine experience due to its size and dietary needs.
Temperament: Generally peaceful but may show territorial behaviour towards similar tang species. Best kept singly or in a large tank with ample swimming space.
Diet: Primarily herbivorous; requires a diet rich in marine algae and seaweed. Supplement with high-quality herbivore flakes, pellets, and occasional meaty foods to ensure balanced nutrition.
Minimum Tank Size: 250 litres (approximately 65 gallons) or larger to accommodate its active swimming behaviour and growth potential.
Lighting and Water Flow: Standard reef lighting and moderate water flow are ideal to simulate natural conditions and support algal growth for grazing.
Placement: Mid to upper levels of the aquarium, with plenty of open swimming space and hiding spots among live rock.
Origin: Not Provided – typically found in Indo-Pacific reef environments.
Maximum Size: Up to 40 cm (approximately 16 inches) in length.
Reef Safety: With Caution – generally reef safe but may nip at certain sessile invertebrates or soft corals; monitor behaviour closely.
This species benefits from a stable, mature aquarium environment with excellent water quality and regular feeding of appropriate herbivore foods. Avoid aggressive tank mates and provide ample space to reduce stress and territorial disputes.
