The Naso Tang, Naso lituratus, also known as the Lipstick Tang or the Orangespine Unicornfish, due to it's outstanding appearance, featuring orange lips and a pair of spines surrounded by a bright orange area on either side of the caudal peduncle. Like all Naso species, they have the ability to quickly and dramatically change, depending on mood or environment. When excited or hiding in the reef their body can become almost black with gray splotchy patches.
The Naso Tang requires a tank no less than 130 gallons as a fully matured adult. The Naso Tang likes water with a moderate to heavy flow, creating currents to swim in. Being very active during the day, they require a large tank with plenty of open room to swim about while also providing plenty of live rocks and or Corals to offer some cover if frightened, and to sleep in at night. Lush natural algae growth in the tank is suggested in order for the Tang to be able to graze upon in between meals. They may also jump out of an open aquarium, so be sure to have a tightly fitting lid.
Keeping naturally growing algae in the tank will help with this, along with blanched lettuce and brine shrimp to entice it to eat. Their diet should consist of natural algae, as well as prepared frozen formulas containing algae or spirulina. Japanese Nori or other seaweed can be offered by attaching it with a vegetable clip to a rock or the glass. Vitamin enriched frozen brine and mysis shrimp should also be offered to help with a balanced diet. Live rock with heavy algae growth is ideal, as it will allow the Tang to scrape it teeth along the rock.
