      Scientific Name: Acanthurus triostegus
      Max. size: 27.0 cm TL (male/unsexed)
      Environment: reef-associated; marine; depth range 0 - 90 m
      Climate: tropical; 24 - 26°C
      Distribution: Indo-Pacific = throughout the region except for the seas around the Arabian Peninsula. Eastern Pacific = lower Gulf of California to Panama, Revillagigedo Islands, Cocos Island, Clipperton, and the Galapagos.
      Morphology: Dorsal spines (total): 9; Dorsal soft rays (total): 22-26; Anal spines: 3; Anal soft rays: 19-22. Body olivaceous gray, with 4 vertical stripes (1 stripe on head across the yellow eye; 1 on caudal peduncle); shading to white ventrally, often with a sharp line of demarcation. Sharp, forward-pointing, erectile spine on each side of caudal peduncle which folds down into a groove. Scales minute. Teeth with denticulations on sides and top. Gill rakers 18-22 in anterior row, 19-24 in posterior row.
      Biology: Occur in lagoon and seaward reefs with hard substrate; young abundant in tide pools. Occasionally form schools; feed on filamentous algae in large aggregations. During spawning, clouds of eggs and sperm are preyed upon by eagle rays which are often present during spawning. Form spawning aggregations. Size of metamorphosis from post-larva stage to juvenile is 3.2 cm.
      Aquarium Care: Grazes on filamentous microalgae and small fleshy macroalgae. One of the least aggressive Acanthurus spp.. If keeping more than one in a large aquarium, add them together. The Convict Tang is more apt to be picked on by other Tangs. If to be kept with other genus, Naso and Zebrasoma are good choices.
