The Yellow Mimic Tang is also commonly known as Mimic Lemon Peel Tang, Yellow Mimic Tang and Mimic Surgeon. In its juvenile stage, it exhibits a bright yellow colored circular body that adds a splash of vivid yellow to your tank. The Juvenile Yellow Mimic Tang fish changes its body color as it grows and matures. Often it tries to mimic the pygmy angelfish such as Centropyge eiblii, C. flavissimus, or C. vroliki and hence it is named appropriately as the Juvenile Yellow Mimic Tang. It does so to camouflage and protect themselves from predators. As the Juvenile Yellow Mimic Tang matures, it uses its spines on the tail as its defense mechanism.  Younger Juvenile Yellow Mimic Tang can be kept in a group but as it grows, it attains the territorial behavior and becomes aggressive. It requires a tank with ample space to swim and lots of hiding place to hide when frightened or sleeping.
