Hemitaurichthys zoster (Bennett, 1831), also known as Indian Silver spotted butterfly fish, is one of the genus Chardonnay of Phalaenopsis family. There is a wide white band in the center of the body. Other parts (except the tail fin) are black brown. The tail fin is gray white and the body color is not bright. However, it is adopted by experts because it is different from other butterfly fish. Feeding in the aquarium requires domesticated bait, which can be fed to animal plankton. Inhabiting in the open waters at the edge of the coral reef area, it often appears in groups and is carnivorous. It feeds on the organisms attached to the coral reef.
