The Purple Tang (Zebrasoma xanthurum) is a stunning saltwater fish known for its deep violet body and bright yellow tail, making it a standout in reef aquariums. Native to the Red Sea and western Indian Ocean, it inhabits coral-rich areas where it grazes on algae. This species is highly valued for its role in algae control and its vibrant coloration, though it can be territorial, especially toward other tangs. Purple Tangs are generally hardy but require ample swimming space and a well-established tank. Their bold personality and beauty make them a favorite among experienced aquarists.
