The **Gem Tang** is a highly coveted and expensive fish for marine aquariums. Known for its striking black body adorned with white spots and a vibrant yellow tail, the **Gem Tang** is a standout addition to any tank. As one of the larger Zebrasoma tangs, it can grow up to 9 inches in captivity and requires a tank of at least 220 gallons for ample swimming space.

While generally peaceful, the **Gem Tang** may exhibit aggression towards other Zebrasoma tangs with similar shapes. To minimize this, it's advisable to introduce multiple tangs simultaneously. This species is reef-safe, making it a suitable choice for tanks with invertebrates and corals.

As herbivores, **Gem Tangs** thrive on a diet rich in greens. Providing plenty of live rock will supply the algae they need. Supplement their diet with nori, flake foods, high-quality pellets, and Mysis shrimp for optimal health.

The rarity and limited geographic distribution of the **Gem Tang**?found only in Southern Africa, Mauritius, and Madagascar?contribute to its high price. If you manage to acquire one, the **Gem Tang** can be a stunning and long-lived centerpiece for your aquarium.
