Introduction to the Sohal Tang

The Sohal Tang (Acanthurus sohal), also known as the Sohal Surgeonfish or Arabian Tang, is a magnificent marine fish that belongs to the Acanthuridae family. They are known for their stunning appearance, featuring a luminescent body with wavy black and white horizontal lines, and bright yellow accents on their pectoral fin and tail. Native to the reef flats in the Western Indian Ocean, between the Red Sea and the Persian Gulf, the Sohal Tang inhabits sandy areas around coral reefs at depths of up to 100 feet.

Despite their beauty, Sohal Tangs can be quite territorial and aggressive, especially towards other members of their species. Therefore, it is essential to provide the proper care and environment for these fish to thrive in a home aquarium. This guide will cover all aspects of Sohal Tang care, including tank size, water parameters, diet, and tankmates.

Species Summary

Scientific Name

Acanthurus sohal is the scientific name for the Sohal Tang, a member of the Acanthuridae family, which includes various types of surgeonfish.

Natural Habitat

Sohal Tangs are tropical aquatic animals that inhabit the sandy areas surrounding coral reefs at depths of up to 100 feet. They originate from the reef flats in the Western Indian Ocean, between the Red Sea and the Persian Gulf. To ensure the well-being of your Sohal Tang, it is crucial to mimic their natural habitat as closely as possible within your aquarium.


The Sohal Tang boasts an elongated, ovoid-shaped body adorned with wavy black and white horizontal lines running its entire length. Bright yellow accents on their pectoral fin and tail give these fish their striking appearance. Additional notable features include their triangular-shaped head, large eyes, and small mouth, as well as their “scalpel” – a sharp spine located at the base of their tail fin.


Under optimal conditions, Sohal Tangs can live for an impressive 15 to 20 years. However, their lifespan depends heavily on factors such as their diet, overall health, and the quality of their environment. Proper care and attention to these factors can significantly increase the longevity of your Sohal Tang.

Average Size

As one of the largest species seen in aquariums, the average size of a mature Sohal Tang is about 16 inches. Providing these majestic creatures with ample room to swim and explore not only ensures their physical well-being but also promotes good mental health.

Sohal Tang Care Requirements

To successfully care for a Sohal Tang, several factors must be considered and maintained, including the appropriate tank size, ideal water parameters, a nutritious diet, and minimizing stress. While caring for these fish may be challenging, with dedication and close attention to detail, they can lead long, healthy lives.

Tank Size

Given their size and active nature, a 250-gallon tank is the recommended minimum size for housing a Sohal Tang. A larger tank provides more room for swimming and reduces the likelihood of stress or injury from bumping into objects. Ideally, the tank should be at least 8 feet in length to accommodate their constant swimming and foraging for algae.

Water Parameters

Maintaining the proper water parameters is crucial for the health of your Sohal Tang. The following parameters should be closely monitored and maintained:

  • pH: 8.1-8.4
  • Temperature: 72-78 degrees Fahrenheit
  • Salinity: 1.020-1.025

Water Temperature

Sohal Tangs prefer a water temperature between 72 and 78 degrees Fahrenheit. This range mimics the warm tropical waters they naturally inhabit and keeps them comfortable. Cold water can cause sluggishness and make them more susceptible to bacterial and fungal diseases.

pH Levels

The ideal pH range for Sohal Tangs is 8.1 to 8.4. Maintaining the correct pH is essential for the overall health of your aquarium. Test your water regularly using test strips or a digital pH meter and make any necessary adjustments to keep the pH within the recommended range.

Water Hardness and Specific Gravity

The water hardness should be maintained at around 420 ppm, with a pH between 7.8 and 8.4. Additionally, the specific gravity, or level of salinity, should fall between 1.020 and 1.025. Monitor these levels frequently and make adjustments as needed to maintain a healthy environment for your Sohal Tang.

Tank Setup

Proper tank setup is crucial to the well-being of your Sohal Tang. Ensure that all filters are functioning correctly, water chemistry has been tested and adjusted as needed, and all necessary equipment is in place before introducing your fish to their new environment.


Sohal Tangs require moderate lighting, with fluorescent lights or LED strip lights being the most suitable options. Avoid overly intense or direct light, as this can cause stress and discomfort for your Sohal Tang.


A robust filtration system is necessary for maintaining pure, well-oxygenated water in your Sohal Tang’s tank. Choose a filter designed specifically for saltwater aquariums, and ensure it is capable of handling the size of your tank and the bioload of your fish.


When introducing your Sohal Tang to its new tank, it is essential to acclimate them slowly to minimize stress and shock. Gradually adjust the temperature, salinity, and pH of the water in their temporary container to match that of the main tank, and introduce them to their new home over the course of several hours.

Are Sohal Tangs Reef-Safe?

While Sohal Tangs are generally considered reef-safe and are unlikely to harm coral polyps, they can exhibit aggression towards other fish, particularly other Tangs. To minimize territorial behavior, it is recommended to introduce them last into the aquarium and to house only one Sohal Tang per tank.

Common Diseases and Prevention

Although Sohal Tangs are not particularly prone to diseases, they can still develop bacterial and fungal infections, as well as Head and Lateral Line Erosion (HLLE). HLLE is characterized by tiny, pitted holes that begin around the eye and spread outward across the head and back. This condition is often caused by poor water quality and an improper diet but can be treated if caught and addressed promptly.

To prevent disease and maintain a healthy Sohal Tang, follow these recommendations:

  1. Maintain high water quality by performing regular water changes and monitoring water parameters.
  2. Quarantine new fish for several weeks before introducing them to the main tank.
  3. Provide a balanced, varied diet that meets the nutritional needs of your Sohal Tang.
  4. Ensure your fish have sufficient space to swim and thrive without crowding.

Food and Diet

Sohal Tangs have a hearty appetite and require a diverse diet to maintain optimal health. As primarily herbivores, their diet should consist mostly of algae-based foods, including frozen herbivore formulations, herbivore pellets, dried marine algae, spirulina-based commercial foods, and fresh vegetables such as lettuce, peas, and spinach. Supplement their diet with nori, enriched brine shrimp, krill, and enriched mysis shrimp. To guarantee adequate nourishment, feed your Sohal Tang at least three times daily.

Behavior and Temperament

Sohal Tangs can be territorial and aggressive towards other fish. They may bully smaller or less aggressive tankmates, so it is essential to choose tankmates wisely and monitor their behavior closely. Providing ample space, hiding spots, and a well-maintained environment can help reduce aggression and stress.

Sohal Tang Tank Mates

Choosing suitable tankmates for your Sohal Tang is crucial to maintaining a peaceful and harmonious aquarium environment. Some appropriate tankmates include:

  • Angelfish
  • Tuskfish
  • Triggerfish

Avoid housing Sohal Tangs with other aggressive or territorial fish, such as Triggerfish or Lionfish, to minimize the risk of conflict and stress in the tank.


Breeding Sohal Tangs in captivity is a challenging task, as they rarely breed in home aquariums. Most Sohal Tangs available for purchase are wild-caught rather than captive-bred. While they are a monogamous species and mate for life, it is challenging to keep more than one Sohal Tang in a tank due to their territorial nature.

Breeding Sohal Tangs is not recommended for most hobbyists due to the complexity and difficulty involved in the process. However, if you are determined to breed these fish, consult with experienced breeders and conduct thorough research to maximize your chances of success.


Caring for a Sohal Tang in your home aquarium can be a rewarding experience for any marine fish enthusiast. By providing a clean, stable environment, a nutritious diet, and appropriate tankmates, your Sohal Tang can thrive and live a long, healthy life. With proper care and attention, your Sohal Tang will bring beauty and enjoyment to your aquarium for years to come.
