Facts and Information
A close relative to the Lined Surgeon (aka Clown Tang) from the Indo-Pacific. The Sohal and Lined Surgeonfish are both large (to 15 inches) and very territorial and aggressive, and by most accounts, the most aggressive of all the seventy-plus members of the Acanthuridae (acanthus=greek for spine) family. These fish inhabit highly oxygenated surge areas of seaward reefs where heavy tide action washes away wastes keeps the churning water at near saturated levels of oxygen. Tangs eat constantly and expell large amounts of waste, especially large ones like the Sohal, but are also highly intolerant of the build-up of such wastes. Some would say tangs are veritable "ich" magnets, and in less-than ideal conditions this is certainly true. Vigorous filtration and dilligent maintainence of the filters is a requirement for keeping the Sohal happy.
