🐠 Dussumieri Tang (Acanthurus dussumieri)
Marine Reef-Safe-With-Caution Tang • Genuinely Rare Deep-Water Species • Friendlier-Than-Average Large Tang • Advanced Keepers, Very Large Tank Required
 
📋 The Dussumieri Tang (Acanthurus dussumieri), also known as the Eyestripe Surgeonfish, is a genuinely impressive large tang with an olive-yellow to tan body, a distinctive yellow stripe linking both eyes, and an intricate maze of fine blue lines across its head and body that intensify with mood.
Native to deep coastal reef slopes and outer reef walls across the Indo-Pacific, from East Africa to Hawaii and the Line Islands, this species is genuinely seldom seen in the trade — it's collected from meaningfully deeper water than most reef fish, giving it a real "elite" reputation among dedicated tang keepers when it does become available.
We want to be upfront: this is one of the largest Acanthurus tangs, reaching up to 54cm in the wild and commonly 35–40cm in well-kept home aquariums, so it genuinely needs a very large, spacious tank from the outset. The encouraging news is that despite its size, it's regarded as one of the more peaceful, less aggressive tangs in its genus, and can often be kept alongside other tang species in a suitably large system with careful introduction.
