Orange Shoulder Tang

Orange Shoulder Tang: The Transforming Algae Grazer

The Orange Shoulder Tang (Acanthurus olivaceus), also known as the Orange Spot Tang, is a very popular and beneficial addition to a marine aquarium. This tang is unique for its dramatic transformation from juvenile to adult. Juveniles are a beautiful bright yellow, while adults develop a brownish or grayish body with a prominent orange patch behind the pectoral fin. It is a peaceful fish but can be territorial towards other tangs, so it's often best to introduce it to the tank last. As a herbivore, it is a fantastic algae-eater, making it a valuable and hardworking member of any clean-up crew. It is completely reef-safe and will not harm corals or invertebrates.

Why the Orange Shoulder Tang is a Great Choice:

• Stunning Appearance: Its unique coloration, especially the juvenile phase, makes it a true showpiece.
• Excellent Algae Control: It tirelessly grazes on nuisance algae, helping to keep the tank clean and healthy.
• Completely Reef-Safe: It will not harm corals, clams, or other invertebrates.
• Active Swimmer: It adds a lot of energy and graceful movement to a spacious aquarium.
