Gem Tang

The Gem Tang is one of the most iconic and sought-after surgeonfish in the marine aquarium trade. Native to the western Indian Ocean, this species is instantly recognizable by its deep black body accented with evenly spaced white spotting, creating a striking, high-contrast appearance that stands out in any display.

Highly valued for both its rarity and visual impact, the Gem Tang is best suited for large, established reef systems with ample swimming space. Like other members of the Zebrasoma genus, it exhibits moderate territorial behavior and should be introduced thoughtfully, particularly when housed with other tang species.

This species is primarily herbivorous and thrives on a diet rich in marine algae, supplemented with high-quality prepared foods. When properly acclimated and maintained in a stable environment, the Gem Tang is a hardy and long-lived addition to a well-managed system.
