Sohal Tang

Scientific Name: Acanthurus sohal
Family: Acanthuridae

About the Sohal Tang

Species Type: Saltwater Fish
Category: Tangs & Rabbitfish

Care Level: Moderate. Healthy specimens are frequently available for purchase, but stress in shipping does sometimes occur. Will accept dried foods after settling in, but frozen foods or algae grazing sheets may be required initially. After proper quarantine and acclimation to the display, this fish is generally resistant to disease. An overall good choice for the new saltwater hobbyist.
Origin: Endemic to the Red Sea
Compatibility/Temperament: The Sohal Tang is one of the more aggressive of all Tangs. They are generally not a good community fish, and are best kept in a reef environment with smaller fish that do not pose a threat. Attempts to keep the Sohal Tang in a mixed community should only take place in the very large home aquariums, say 400 gallons or larger. If kept with other Tangs, it is best to avoid mixing it with members of the Acanthurus genus, such as the Powder Brown or Powder Blue Tangs.


It is the most aggressive of all tangs and can be a terror in the typical home aquarium. Those wishing to keep a Sohal should consider doing so in a reef environment that is extremely large, allowing ample swimming room for the adult size of this fish. Potential tankmates should be smaller reef dwelling fish, such as Clownfish, Damselfish, Gobies, Blennies, Dottybacks, Anthias, and Wrasse.

Sohal Tang Diet

Feed a diet rich in vegetable matter including frozen herbivore foods, dried seaweed, or live macro algae. Freeze dried algae sheets should be offered daily.


The Sohal Tang grows huge, nearing 24'' in length, and is regularly featured in large public aquariums.

Minimum Tank Suggestion

400 gallons

Ideal water parameters for Sohal Tang

Marine fish are highly sensitive animals with very specific care requirements. Most all saltwater species will require similar water conditions, designed to replicate that of natural seawater. Ammonia and nitrite levels should absolute zero, temperature at 76F to 80F, and salinity at 1.024 to 1.026. Although some fish are tolerant of lower levels of Nitrate, the goal in every aquariums should be to keep Nitrate as close to zero as possible, and certainly under 20ppm. Finally, maintaining a stable pH of 8.0 to 8.4 is desired. Achieving this is made easier by monitoring alkalinity, which should be kept at 8-12 DKH, and calcium, which is targeted at 400 to 460ppm.
