Purple Tang Fish

The Purple Tang, *Zebrasoma xanthurum*, is a highly sought-after and visually stunning surgeonfish known for its vibrant, deep purple body and bright yellow tail. This striking color combination makes it a standout addition to any marine aquarium.

A minimum tank size of 125 gallons is recommended for a single Purple Tang to provide ample swimming space and reduce stress. They are active swimmers and require a well-established aquarium with plenty of live rock for grazing on algae and providing hiding places. While generally considered reef-safe, some individuals may occasionally nip at certain corals or invertebrates, especially if not well-fed with a varied diet.

Purple Tangs are primarily herbivores, and their diet should consist mainly of marine algae. Offer a variety of foods including dried seaweed (nori) attached to a rock or clip, high-quality marine flake and pellet foods containing Spirulina, and occasional offerings of mysis shrimp or other meaty foods to provide essential nutrients. A diet rich in algae is crucial for maintaining their vibrant coloration and overall health.

In a home aquarium, Purple Tangs can reach a size of approximately 8-10 inches. They are generally peaceful towards other fish, but can be territorial towards other tangs or fish with similar body shapes. Introducing them as one of the last fish to the aquarium can help minimize aggression. There are no readily apparent visual differences between male and female Purple Tangs. Breeding in a home aquarium is extremely difficult and rarely achieved.
