Gem Tang

Gem Tang (Zebrasoma gemmatum) is a semi-aggressive species that is reef-safe as it poses no threat to corals or most invertebrates, focusing primarily on algae grazing. This spectacular species displays a dark purple to black body covered with distinctive white spots that resemble scattered gems, giving it its common name, plus dramatically enlarged dorsal and anal fins that create an impressive sailfin silhouette when fully extended. The striking white-spotted pattern against the dark background makes it one of the most sought-after and visually stunning tangs in the aquarium trade. It can reach about 8 inches in adult size. Best kept in tanks of at least 75 gallons or more due to their active swimming nature and territorial behavior toward other tangs, with plenty of live rock for grazing, strong water flow, excellent water quality, and consideration for their rarity and high value that makes them prized centerpiece fish for serious collectors. Its diet should include a mix of marine algae—nori sheets, spirulina, dried seaweed, algae pellets—as well as high-quality herbivore foods and occasional meaty supplements like mysis shrimp, as this primarily herbivorous species requires constant access to plant matter and benefits from varied nutrition to maintain their spectacular gem-like spotted pattern and overall health.
