Sohal Tang (Acanthurus Sohal)
Sohal Tang (Acanthurus sohal)
The Sohal Tang, also known as the Majestic Tang or Red Sea Clown Surgeonfish, is the undisputed "King" of the Acanthurus genus. While most of the fish you've looked at today are native to your local Indonesian waters, the Sohal—like the Purple Tang—is an exotic inhabitant of the Red Sea. It is legendary in the hobby for three things: its stunning "pinstripe" beauty, its incredible swimming speed, and its high level of aggression.
Key Information
-
Common Names: Sohal Tang, Sohal Surgeonfish, Majestic Tang
-
Scientific Name: Acanthurus sohal
-
Origin: Red Sea and the Persian Gulf
-
Max Size: 35–40 cm (approx. 14–16 inches)
-
Lifespan: 15+ years
-
Temperament: Very Aggressive; highly territorial
-
Diet: Herbivore – Algae grazing specialist
-
Care Level: Moderate to Difficult (due to size and aggression)
Appearance & Identification
The Sohal Tang looks like a high-performance sports car:
-
The Pinstripes: A sleek, silver-to-grey body covered in fine, horizontal black-to-blue stripes that run from head to tail.
-
The Highlights: The fins are jet black and edged in a glowing electric blue.
-
The Orange Splash: A bright orange patch is located just behind the pectoral fins, and the "scalpel" (the defensive spine at the tail) is also a vivid orange.
-
The Silhouette: Unlike the "round" Sailfin Tang, the Sohal is elongated and muscular, built for high-speed swimming in heavy surf.
Behaviour & Tank Compatibility
-
The Dominant Force: The Sohal Tang does not just live in a tank; it owns the tank. As they mature, they become increasingly intolerant of other fish, especially other tangs or anything that swims in "their" open water lanes.
-
Aggression: This is one of the most aggressive fish in the trade. It uses its orange caudal spine with surgical precision to "slash" at rivals.
-
Reef Safe: 100% Reef Safe with corals, but its high activity level can sometimes stress out very delicate or shy fish.
-
Social Structure: Must be kept singly. Do not attempt to house two Sohals together unless you have a public-aquarium-sized system.
-
Tank Mates: Best kept with similarly large, aggressive fish like large Triggers, Groupers, and large Angelfish. It should almost always be the last fish added to the aquarium.
Ideal Tank Setup
-
Tank Size: This is non-negotiable—a minimum of 680L (180 Gallons) for a juvenile, but 950L+ (250+ Gallons) is highly recommended for an adult. They need a minimum of 6 to 8 feet of swimming length.
-
Water Flow: They require extremely high flow. They are naturally found in the "surge zone" of the Red Sea. Massive wavemakers and high oxygenation are essential.
-
Rockwork: Provide large, stable rock structures but keep the center of the tank completely open for swimming.
-
Hardiness: Once acclimated, they are incredibly "bulletproof" and disease-resistant, though like all tangs, they are prone to Marine Ich if stressed.
Dietary Needs
To maintain their energy and prevent HLLE:
-
Primary Diet: Constant access to Nori (dried seaweed). They have a massive metabolism and need to graze all day.
-
Supplemental: Spirulina-enriched flakes, mysis shrimp, and high-quality herbivore pellets.
-
Vitamin Boosting: Soak their food in Garlic Guard or Selcon to maintain their immune system and keep their electric blue colors vivid.
Why Choose the Sohal Tang?
The Sohal Tang is for the hobbyist who wants a "Showstopper" that commands attention. It is a prestigious, high-energy fish that brings a sense of power and motion to a large reef. While its aggression requires careful planning, there is no other fish that matches the Sohal’s combination of geometric beauty and sheer aquatic presence.
