The yellow tang (Zebrasoma flavescens) is a saltwater fish species of the family Acanthuridae. It is one of the most popular aquarium fish.
It is commonly found in shallow reefs, from 2–46 metres (6.6–150.9 ft) deep, in the Pacific and Indian Oceans, west of Hawaii and east of Japan. Hawaii is the most common place for aquarium harvesting, where up to 70% of the yellow tangs for the aquarium industry are sourced from.
The yellow tang has been recorded in waters around Florida, where it is not native.
