Naso unicornis

Naso unicornis, commonly known as the bluespine unicornfish, is a beautiful very large unicornfish which needs plenty of swimming space. It can be aggressive towards other fish, especially tangs and food competitors, but will be the showpiece of your aquarium.

Like other unicornfish, it will eat zooplankton, but it's important it can graze on algae/seaweed the entire day to ensure it will stay healthy. So feed flakes/pellets multiple times a day and make sure there is always seaweed available.
