This is a beautiful fish that is rarely seen. Notice the orange ‘tang’ on the caudal peduncle just in front of the tailfin. Also the fluorescent blue fringe on the edges of the fins. Isn’t the Sohal Tang or Red Sea Clown Tang magnificent!

   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.
