Common name: Unicornfish

The genus Naso includes several species of unicornfish, known for their distinctive horn-like protrusions on the forehead of some species. These tangs are popular in the reefkeeping hobby for their unique appearance and active swimming behavior. They are generally peaceful but can grow quite large, making them suitable for spacious aquariums. They are herbivorous, feeding primarily on algae, and can help control algae growth in a reef tank.
