🐠 Dussumieri Tang (Acanthurus dussumieri)
Marine Surgeonfish • Large Algae Grazer • Reef-Associated Species • Open-Water Swimmer
 
📋 The Dussumieri Tang (Acanthurus dussumieri) is a majestic, large-growing surgeonfish known for its bluish body, golden facial patterns, and sweeping tail crescents. As it matures, the species develops rich color gradients and distinctive markings that make it a showpiece for large marine aquariums.
This species is an active open-water swimmer, requiring ample space and strong water movement. Like other Acanthurus species, it may show territorial behavior toward similarly shaped tangs but generally coexists well with other large marine fish in appropriately sized systems.
A powerful algae grazer, the Dussumieri Tang plays a beneficial role in keeping rock surfaces clean. Its combination of size, beauty, and constant motion makes it a prized addition to large reef or fish-only display tanks.
