Naso Tang
Naso lituratusAlso known as Orangespine Unicornfish, Clown Unicornfish, Blackfinned Unicornfish, Stripefaced Unicornfish
Orangespined unicornfish glide gracefully over shallow coral reefs, using their specialized teeth to graze on leafy brown macroalgae. While they lack the prominent forehead horn of some close relatives, their striking facial markings and bright orange caudal spines make them unmistakable underwater. These social fish often forage in pairs or small groups, playing a vital role in keeping algae growth from smothering the reef.
