Whitecheek Goldrim Tang – Acanthurus nigricans

Acanthurus nigricans—often called the Whitecheek or Goldrim Tang—is a sleek, reef-safe herbivore that adds constant motion and refined contrast to larger marine aquariums. Its charcoal body, golden rim, and distinct white cheek patch make it a standout among tangs. Active and alert, this species thrives in mature 125–150+ gallon systems with open swimming lanes, strong oxygenation, and plenty of established live rock to graze. Semi-aggressive toward other tangs (especially similar shapes), it’s best kept singly or added last to the community. Feed an algae-rich diet—nori/seaweed on clips, spirulina pellets, quality herbivore blends—with occasional mysis to maintain color and condition. Known to be sensitive to poor water quality, the Whitecheek Tang rewards stable parameters and regular feedings with robust health and excellent film algae control.
