Acanthurus sohal
A large surgeonfish endemic to the Red Sea and Arabian region. Fine black lines on a pale body; fins are black with vivid blue edges. Extremely aggressive, needs a tank of 950L or more and should be the last fish added.
The Sohal Tang (Acanthurus sohal) is a large surgeonfish endemic to the western Indian Ocean from the Red Sea to the Persian Gulf. Fine black lines run along a pale grey-green body; the dorsal, anal and pelvic fins are black with electric-blue edges, and orange patches sit behind the pectoral fin and around the tail spine. FishBase records a maximum of 40cm (total length); it is common on surge-exposed outer reef edges at 0-20m. It grazes Sargassum and filamentous green algae and is strongly territorial. It is hardy in captivity, but its size and aggression are the challenge, and a tank of 950L or more is recommended. Avoid other tangs and add it as the last fish in the tank. Feed mainly seaweed, supplemented with brine and mysis shrimp. It does not harm corals and suits reef tanks. Watch for marine ich; quarantine and keep water stable. There is no standard Japanese name; the trade names Sohal Tang and Sohal Surgeon are used.
