Gold Rim Tang

About this fish

The Gold Rim Tang is a saltwater tang for the home aquarium. Its scientific name is Acanthurus nigricans (as listed). This active grazer is commonly used to help bring algae-control benefits through constant feeding while also adding an eye-catching presence in a reef-style tank. Because tangs are built for long, open swimming, it’s best suited to aquariums with plenty of horizontal room and stable, established conditions. With routine feeding and careful introduction, the Gold Rim Tang can be a great addition for hobbyists who want a busy reef fish and are prepared to plan tank space and tankmate compatibility.

Features:

• Active, fast-moving grazer that spends much of its time feeding
• Helps “work” at algae in the tank when provided appropriate foods
• Bold, reef-friendly look—often chosen for display in tang and surgeonfish setups
• Sharp spine near the tail; handle carefully and plan interactions
• Can be territorial toward other tangs, so tankmate selection matters
• Most are generally reef safe with corals when tank is set up thoughtfully
• Arrives best with slow acclimation and a quiet settling spot
