Naso elegans, commonly known as the blonde Naso tang, is a beautiful 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. It looks very similar to Naso lituratus, but the elegans has a yellow dorsal fin, where lituratus has a black dorsal fin.
It 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.
