Convict Tang – Acanthurus triostegus
Overview:
The Convict Tang is a small, striking marine herbivore, easily recognized by its silver-white body marked with bold vertical black stripes. Its peaceful nature, active swimming, and algae-grazing behavior make it a popular choice for reef aquariums.
Origin:
Native to the Indo-Pacific, commonly found on coral reefs, lagoons, and shallow coastal areas from East Africa to the central Pacific.
