Lavender Tang (Acanthurus nigrofuscus)

Acanthurus nigrofuscus—commonly the Lavender Tang or Brown Surgeonfish—is a diligent, reef-safe herbivore that brings constant motion and excellent algae control to your display. Subtle lavender-brown tones with fine reticulated scaling make this tang a refined centerpiece without overpowering bold corals. Peaceful to semi-aggressive, it may defend territory against other tangs—especially similarly shaped species—so introduce last or keep singly in mixed communities. Provide a mature 90–120+ gallon aquarium with open swimming lanes, strong oxygenation, and plenty of established live rock to browse. Feed an algae-rich diet (nori on clips, spirulina pellets, and quality herbivore blends) with occasional mysis for condition. The Lavender Tang is considered a reef safe fish and rarely bothers corals while it targets film algae and diatoms.
