I will use “Naso Tang” as the primary common name and “Orangespine Unicornfish” or “Lipstick Tang” as secondary.

**Appearance & Behaviour (Overview):**

* Can change coloration based on mood/environment.
* Adults usually in small groups, juveniles sometimes in aggregations.
* Known to jump from open aquaria.

**Care Level:**
* **Difficulty:** Moderate to Advanced/Experienced.
* **Temperament:** Generally peaceful with other non-Tang species after establishing pecking order. Can be aggressive towards other tangs, especially similar species or those of similar shape/genus. Semi-aggressive. “One per tank” is often recommended for other tangs.
* **Compatibility:** Reef-safe. Does not nip corals if well-fed. Compatible with clownfish, angelfish, wrasses, butterflyfish, gobies.

**Tank Essentials:**

* 100 gallons (380 liters) for adult specimens, but larger preferred.

* **pH:** 8.1-8.4 – Consistent.
* **Salinity/SG:** 1.020-1.025 – Consistent.
* **Other Needs:** Strong water flow, high oxygen levels, ample swimming space, hiding places (live rock), tight-fitting lid (jumps).

**Diet:**

* Feeds mainly on leafy brown algae (e.g., *Sargassum*, *Dictyota*).
* Needs significant algae-based food (Nori, spirulina, seaweed sheets, flakes/pellets enriched with spirulina).
* Will graze on algae from rocks.
* Accepts occasional meaty foods (mysis, brine shrimp, krill) for variety/nutrition.
* Feed multiple times a day. A well-fed tang reduces aggression and HLLE.

Naso Tang: A Majestic Algae Grazer for Large Reef Aquariums

Bring vibrant activity and natural algae control to your spacious marine environment with the stunning Naso Tang. This iconic surgeonfish is a true spectacle!

Overview

The Naso Tang, also known as the Orangespine Unicornfish, features a distinctive brownish-grey body, often with a lighter dorsal side, accented by a bright yellow nape. Its most striking attributes are the vivid orange lips and a yellow-outlined black mask across its snout and eyes. Adult males develop elegant, long filaments on their caudal fin. Active and graceful, this species navigates your aquarium with fluid movements, making it a captivating inhabitant.

Care Level

Considered a moderate to advanced care species, the Naso Tang thrives with dedicated attention. While generally peaceful towards most non-tang tankmates, they can exhibit territoriality towards other tangs, particularly those of similar shape or genus. Ensure ample space and appropriate tankmates for harmonious coexistence. This species is fully reef-safe.

Tank Essentials

A mature aquarium of at least 680 litres (180 US Gallons) is crucial, with larger systems always preferred to accommodate their active swimming habits and adult size. Maintain stable water parameters: a temperature range of 23-27°C, pH between 8.1-8.4, and a specific gravity of 1.020-1.025. Strong water flow and plenty of live rock for grazing and hiding are essential for their well-being.

Diet

As a primarily herbivorous species, the Naso Tang requires a diet rich in marine algae. Offer daily dried seaweed (Nori) on a veggie clip, spirulina-based flakes, and pellets. Supplement occasionally with high-quality frozen meaty foods like mysis shrimp or brine shrimp to ensure a well-rounded diet and support a robust immune system.
