Why Choose the Gem Tang (Zebrasoma gemmatum)?

The Gem Tang is a dream species for serious marine aquarists looking to add a truly rare and mesmerising fish to their collection. Its dazzling spotted pattern and graceful swimming style make it a centrepiece in any well-maintained aquarium. Aside from its breathtaking beauty, this species is an excellent algae grazer, helping to maintain a clean and balanced environment. Due to its high value and sensitivity to stress, it requires a spacious, stable, and well-filtered aquarium with minimal aggression from tank mates.

Care Tips:

• Water Parameters: Maintain pristine water conditions with a temperature of 75°F - 80°F (24°C - 27°C), pH between 8.1 - 8.4, and salinity levels of 1.023 - 1.025. High-quality filtration and strong water movement are essential.
• Feeding: Gem Tangs require a diet rich in algae. Offer seaweed sheets, spirulina-based foods, and naturally occurring algae growth from live rock. Supplement with high-quality marine pellets or flakes. Feed 2-3 times daily.
• Tank Setup: A tank of at least 180 gallons is recommended to provide ample swimming space. Include live rock for grazing and structured rockwork to create natural territories and hiding spots.
• Behaviour: Semi-aggressive, particularly towards other tangs. It is best introduced as the only tang in smaller tanks or carefully introduced to multiple tang species in larger setups. Compatible tank mates should be chosen carefully to avoid territorial disputes.
