If you’ve been searching for a bold, commanding centerpiece fish that brings genuine drama to a large reef system, the Dussumieri Tang (Acanthurus dussumieri), also known as the Eyestripe Surgeonfish, is exactly the kind of fish serious hobbyists spend years working toward. With its striking yellow eye stripe, intricate body patterning, and powerful presence, this is a fish that immediately commands attention in any aquarium it inhabits.

At Dr. Reef’s Quarantined Fish, every Dussumieri Tang we offer has completed our full quarantine protocol, arrived eating confidently, and is genuinely ready for the display tank of an experienced reef keeper.

What Makes the Dussumieri Tang So Impressive?

The Dussumieri Tang is one of the larger surgeonfish available in the marine hobby. Its body is covered in fine blue-grey vermiculations, it carries a vivid yellow mask around the eye, and its sharp tail spine demands respectful handling. This is not a beginner fish. It is a species that rewards experienced aquarists who understand the demands of keeping a large, active surgeonfish in peak condition.

The Size Reality: Built to Dominate a Large Tank

Dussumieri Tangs are among the larger members of the Acanthurus genus, with adults routinely reaching 18 to 20 inches in the wild. In home aquariums, well-kept specimens commonly reach 14 to 16 inches, making them one of the most substantial tang species available to hobbyists. A fully grown Dussumieri Tang is a powerful, fast-moving animal that needs serious space to express natural swimming behavior. Cramped quarters compromise its health, dull its coloration, and create the stress conditions that lead to disease and aggression. 

Growth Timeline: Planning for the Long Term

Dussumieri Tangs grow steadily over several years. A juvenile of 3 to 4 inches will reach 7 to 8 inches within the first 18 months under good care. By years three to four, expect a healthy individual to approach 12 inches. Full adult size develops by years five to seven, with coloration and patterning deepening significantly as the fish matures.

Tank Requirements and Care

A minimum 250-gallon aquarium is recommended for a single adult, with larger systems always being preferable. Strong, consistent flow that mimics open ocean conditions is essential. Water temperature should stay between 72 and 82 degrees Fahrenheit with salinity at 1.020 to 1.025 SG. The Dussumieri Tang is a natural herbivore. Provide generous amounts of nori, spirulina-based frozen foods, and quality herbivore pellets alongside natural algae growth on live rock. A well-fed Dussumieri Tang is healthy, calm, and visually stunning.

Temperament and Tank Mates

The Dussumieri Tang can be territorial toward other tangs in systems that do not offer enough space. In adequately sized aquariums it generally coexists well with robust, similarly sized fish. Avoid housing it with timid or small species that may be overwhelmed by its size and assertive nature.
