Purple Tang

The Purple Tang is one of the most coveted and visually striking tangs in the marine aquarium hobby, featuring a rich, deep purple body that contrasts dramatically with its bright yellow tail and yellow accents on the pectoral fins. Fine dark spots and lines are scattered across the head and anterior body, adding subtle texture to its appearance. A member of the Zebrasoma genus alongside the popular Yellow Tang, it shares the same laterally compressed, disc-shaped body with a tall dorsal and anal fin profile that gives it a bold, sail-like silhouette. Native primarily to the coral reefs of the Red Sea and western Indian Ocean, the Purple Tang commands premium prices in the aquarium trade due to its limited collection range and high demand.

In the aquarium, the Purple Tang is an active, bold swimmer that readily becomes the dominant presence in the tank. It is an excellent algae grazer that will tirelessly pick at surfaces throughout the day, helping to control nuisance algae growth on live rock and glass. Like its close relative the Yellow Tang, it can be territorial toward other tangs and similarly shaped fish, particularly in smaller aquariums. Its semi-aggressive temperament is typically directed at conspecifics and congeners rather than at dissimilar species. The Purple Tang does best when it is the last fish added to the aquarium, as established specimens may harass new arrivals.

Despite its higher price point and semi-aggressive nature, the Purple Tang is a reasonably hardy species once acclimated to captivity. It is less prone to ich than some other tang species, though quarantine is still strongly recommended. A minimum tank size of 100 gallons with abundant live rock for grazing and open swimming areas is essential. The Purple Tang is completely reef-safe and will not disturb corals or invertebrates. A diet rich in marine algae, supplemented with nori, Spirulina preparations, and occasional meaty foods, will maintain its vibrant purple coloration and overall health for many years.
