The Chocolate Tang (Acanthurus pyroferus) also known as the Yellow Mimic Tang, Mimic Tang, Mimic Surgeonfish and Chocolate Surgeonfish.
During their juvenile stages they have an oval shaped, yellow body with blue highlights around the eyes and gill covers.
As an adult the Chocolate Tang is very similar looking to many other Acanthurus species as far as size and facial features. They are most often found individually around lagoon & seaward reef zones, scouring over coral and rocks.
Juvenile Yellow Mimic Tangs or Juvenile Chocolate Tangs quite often imitate the color and caudal fin shape of the pygmy angelfish (Centropyge argi) & the Lemon peel Angelfish (Centropyge flavissimus) hence the name ‘’Mimic’’. When mature, the body color darkens towards tan with red highlights forming around the eyes & pectoral fins with each assuming their own color and fin shapes, they no longer mimic other fish.
