The Sohal Tang or Red Sea Clown Tang is from the Red Sea and the Western Indian ocean. Although fish from the Red Sea are generally more expensive, they are always net caught and are handled with more care, which gives them a much better survival rate. These fish are somewhat difficult to keep, but you should be able to obtain a very healthy specimen which increases the chances of this fish surviving in the aquarium. The salinity should be kept near 1.025 and constant; pH should be buffered between 8.2 and 8.4., and temperature in the mid seventies to low eighties degrees Fahrenheit. These guys need constant feeding of algae (nori) in small amounts. These tangs are great for the more advanced aquarist.
