Acanthurus olivaceus, the orange-band surgeonfish, the orange-shoulder surgeonfish or the orangebar tang,is a species of marine ray-finned fish belonging to the family Acanthuridae, this family includes the surgeonfishes, unicornfishes and tangs. It lives in the tropical waters of the Indo-west Pacific. Taxonomy Acanthurus olivaceus was first formally described in 1801 by the German naturalists Marcus Elieser Bloch and Johann Gottlob Theaenus Schneider with its type locality given as Tahiti in the Society Islands,This species is closely related to the range restricted Marquesas surgeonfish (A. reversus), and together these taxa form a species complex within the genus Acanthurus.The genus Acanthurus is one of two genera in the tribe Acanthurini which is one of three tribes in the subfamily Acanthurinae which is one of two subfamilies in the family Acanthuridae. Description The orange band surgeonfish is a deep-bodied, laterally-compressed oval fish, rather over twice as long as it is deep, with a maximum length of 35 cm (14 in), although a more typical length is 25 cm (10 in). Both dorsal and anal fins are long and low, extending as far as the caudal peduncle. The dorsal fin has nine spines and 23 to 25 soft rays while the anal fin has three spines and 22 to 24 soft rays. The tail fin is crescent-shaped, the points growing longer as the fish gets older. The adult fish is greyish-brown; a sharp vertical line usually separates the paler front half of the fish from the darker hind portion. There is a distinctive orange bar, surrounded by a purplish-black margin, immediately behind the top of the gill cover, and blue and orange lines at the bases of the fins. Like all surgeonfish, this species has a pair of scalpel-like scales that project upward from the caudal peduncle. Larger males develop a convex snout which clearly differentiates them from females. Juvenile fish are yellow. Distribution and habitat This fish is found in the tropical eastern Indian Ocean and the western Pacific Ocean. Its range extends from Christmas Island and the Cocos Keeling Islands to southern Japan, Western, Northern and Eastern Australia, Indonesia, the Philippines and Hawaii. It is associated with reefs, often on outer slopes and in more exposed locations. As an adult, it is a solitary fish or sometimes joins schools, with a depth range of between about 9 and 46 m (30 and 150 ft), but juveniles are found in shallower water in sheltered locations in small groups. Ecology The orange band surgeonfish feeds on detritus and on algae growing on the seabed, as well as the film of diatoms and filamentous algae that grows on sand and other substrates.[2] It often forms schools with parrotfish, tangs and other species of surgeonfish, which all have similar diets; their grazing is important in maintaining biodiversity by keeping rocks free from excessive growth of algae so that coral larvae can find suitable habitat to settle. The fish can change colour from dark to pale almost instantaneously. Status The orange band surgeonfish has a wide distribution in the tropical Indo-Pacific region and is moderately common. It is sometimes found in fish markets and in the aquarium trade but is not a species targeted by fisheries. No particular threats have been recognised, so the International Union for Conservation of Nature has listed its conservation status as being of least concern.

Naso elegans, the elegant unicornfish, the blonde naso tang, Indian orange-spine unicorn, lipstick surgeonfish, lipstick tang, orangespine unicornfish or smoothheaded unicornfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. This species is found in the Indian and western Pacific Oceans. Taxonomy Naso elegans was first formally described as Aspisurus elegans in 1829 by the German zoologist and explorer Eduard Rüppell with its type locality given as the northern Red Sea. This species is classified within the nominate subgenus of the genus Naso.[The genus Naso is the only genus in the subfamily Nasinae in the family Acanthuridae. For a long time this species was regarded as an Indian Ocean colour morph of the orangespine unicornfish (Naso lituratus) until it was shown that there were consistent meristic differences. Etymology The specific epithet elegans is Latin for "choice", "fine" or "select", a reference to the beautiful colours of this fish. Distribution and habitat Naso elegans is found in the Indian and Pacific Oceans. It occurs in the Red Sea south along the east African coast to Durban in South Africa and eastward across the Indian Ocean into the Pacific where it reaches as far east as Bali in Indonesia. It is absent from the waters off the mainland Indian subcontinent.[1] In Australian waters it has been recorded from Christmas Island and the Cocos (Keeling) Islands. The elegant unicornfish occurs in reef flats in coastal and inshore waters in small schools while in more oceanic waters it forms larger schools, Description Naso elegans has 6 spines and between 26 and 30 soft rays, typically 28, supporting the dorsal fin while the anal fin is supported by 2 spines and between 27 and 30 soft rays, typically 29. The pectoral fin contains 16, or more usually, 17 fin rays. There are between 30 and 35 teeth in each jaw and, in adults, these are similar to incisors and have rounded edges. The body has a depth which is equivalent to roughly a quarter of the standard length and it grows more elongate as the fish grows.The keels on the caudal peduncle are larger in males than in females and the males also have longer filaments growing from the caudal fin. The overall colour is grey, with a dark snout separated from the grey head by a yellow bar at the eyes. The dorsal fin is yellow with a thin blue edge and a black band inside that. The anal and pelvic fins are dark brown.The plates on the caudal peduncle are vivid orange separated by a patch of white.The caudal fin is yellowish with a black submarginal band and black lower and upper edges. The elegant unicornfish has a maximum total length of 45 cm (18 in), although 35 cm (14 in) is more typical. Biology Naso elegans is a herbivore, feeding on benthic algae,[8] particularly brown algae in the genera Sargassum and Dictyota.

Acanthurus triostegus, commonly known as convict tang, manini,convict surgeonfish, convict surgeon, or fiveband surgeonfish, is a species of marine ray-finned fish belonging to the family Acanthuridae which includes the surgeonfishes, unicornfishes and tangs. This species has a wide Indo-Pacific distribution. Taxonomy Acanthurus triostegus was first formally described in 1758 as Chaetodon triostegus by Carl Linnaeus, the description being published in the 10 edition of Systema Naturae with its type locality given as "Indies".The genus Acanthurus is one of two genera in the tribe Acanthurini which is one of three tribes in the subfamily Acanthurinae which is one of two subfamilies in the family Acanthuridae. Etymology Acanthurus triostegus was given the specific name triostegus which means "three covers", this may refer to the three branchiostegal membranes. Description The convict tang is so called because of its bold black stripes on a yellowish background. It is a laterally-compressed oval-shaped fishwith a maximum length of about 26–27 cm (10–11 in). The head is small with a pointed snout and a terminal mouth with thick lips. It has six black stripes which distinguishes it from the zebra tang (Acanthurus polyzona) which has nine, and has a more restricted range in the Indian Ocean. The first black stripe is oblique and passes through the eye. There are two black spots on the caudal peduncle, and on each side there is a sharp, retractable spine, which is used in offence or defence. Distribution and habitat Acanthurus triostegus occurs in the tropical Indo-Pacific region. Its range extends from the East African coast and Madagascar to southwestern Japan, Australia and Central America, including many Pacific island groups. It is found over hard bottoms in lagoons, reef slopes, bays and estuaries. Juveniles are common in tide pools, and larger fish are found at depths down to about 90 m (300 ft). Biology Acanthurus triostegus frequently feed in the vicinity of freshwater discharges, grazing filamentous algae off the rocks.Typically these tangs graze on filamentous algae growing on coral or rocky substrates. The adults aggregate in large schools to feed and these overwhelm damselfishes attempting to defend their territories. The males and females gather in aggegations to spawn. Utilisation Acanthurus triostegus is targeted as a food fish in many parts of its range and in some areas is commercially targeted. In Hawaii it is fished for by recreational anglers and it is also caught for the aquarium trade.

Naso brevirostris, also known as the short-nosed unicornfish, spotted unicornfish, brown unicornfish, lined unicornfish, longnose surgeonfish, palefin unicornfish, paletail unicornfish, shorthorned unicornfish or shortsnouted unicornfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. It occurs in the Indian Ocean and western Pacific Ocean. Taxonomy Naso brevirostris was first formally described as Naseus brevirostris in 1829 by the French zoologist Georges Cuvier with its type locality not given but considered to be Indonesia.[3] It is classified within the nominate subgenus of the genus Naso.[4] The genus Naso is the only genus in the subfamily Nasinae in the family Acanthuridae. Etymology Naso brevirostris has a specific name which means "short nose".  Description Naso brevirostris has 6 spines and between 27 and 29 soft rays supporting the dorsal fin while the anal fin is supported by 2 spines and 27 to 29 soft rays. The depth of the body fits into its standard length between roughly 2 and 2.7 times. The snout is very short in length and is very steep, almost vertical. Subadults and adults have long, tapering bony protuberances in front of their eyes which may extend past one's mouth by as much as the length of the head, first appearing as a bump in individuals of around 10 cm (3.9 in) total length. A pair of bony plates with a poorly developed keels are on each side of the caudal peduncle and the caudal fin varies from truncate to slightly rounded. The overall colour is light blueish-grey to olive-brown, although there is a colour phase where the front quarter of the body is pale with a clear demarcation from the remainder of the body. The middle of the flanks are marked with thin, vertical dark grey lines that break up into small spots on the lower body. The head is marked with small dark spots or by a lattice of lines. The protuberance is marked with diagonal black lines, the membrane of the operculum is white, the lips have pale blue edges and the caudal fin is largely whitish.This species has a maximum published total length of 60 cm (24 in). Distribution and habitat Naso brevirostris is widespread throughout the Indian and Pacific Oceans, from the Red Sea south along the eastern coast of Africa as far as Durban in South Africa and eastward across the Indian Ocean into the Western Pacific Ocean, extending east to the Pitcairn Islands and the Hawaiian Islands, north to southern Japan and south to Australia.[1] In Australia the distribution goes from Ningaloo Reef around the northern tropical coasts to the northern Great Barrier Reef and the Coral Sea as far south as Moreton Bay in Queensland, as well as in the region of Lord Howe Island in the Tasman Sea.In the eastern Pacific it is found around the Galápagos Islands.These fish live in lagoon and seaward reefs down to depths of 46 m (151 ft) Naso brevirostris forms spawning aggregations, pairing to spawn and the males have larger keels on the caudal peduncle than the females. The eggs hatch into pelagic larvae which may remain in the water column for up to 90 days and the adults attain sexual maturity at around 25 cm (9.8 in).Adults feed mainly on gelatinous zooplankton, while juveniles mainly feed on benthic algae. The switch from grazing to preying on gelatinous zooplankton coincides with the development of the bony protuberance.

Zebrasoma scopas, the brown tang, twotone tang, scopas tang or brush-tail tang, is a species of marine ray-finned fish belonging to the family Acanthuridae which includes the surgeonfishes, unicornfishes and tangs. The brown tang is found throughout Oceania and is a herbivorous fish, feeding predominantly on filamentous algae. It is a highly popular fish in the aquarium trade. Taxonomy Zebrasoma scopas was first formally described as Acanthurus scopas in 1829 by the French zoologist Georges Cuvier with its type locality given as Banda Neira in the Banda Islands of Indonesia.[4] The brown tang is part of a species pair within the genus Zebrasoma, along with the yellow tang (Z. flavescens).[5] The genera Zebrasoma and Paracanthurus make up the tribe Zebrasomini within the subfamily Acanthurinae in the family Acanthuridae, according to the 5th edition of Fishes of the World. Etymology Zebrasoma scopas has the specific name scopas, meaning “broom”, a reference to the bristles on the caudal peduncle near the spine. Description Zebrasoma scopas is a laterally compressed, deep bodied fish with a protruding snout which grows to a maximum published standard length of 40 centimetres (16 in). The head is whitish and the body pale brown shading to a dark brownish-black near the black tail. There are faint pale green longitudinal lines starting as dots at the head end and becoming continuous and then dotted again posteriorly. The juveniles are rather paler and have yellowish bars near the anterior end. They also have relatively larger dorsal fins. The adults have a white spine on the caudal peduncle. The large, sail-like dorsal fin has 4 or 5 spines and 23 to 25 soft rays. The anal fin has 3 spines and 19 to 21 soft rays. Distribution Zebrasoma scopas is found in the Indo-Pacific region, living at water depths of up to 60 metres (200 ft).Its range extends from the coasts of East Africa to Japan, the Pitcairn Islands, Malaysia, Indonesia, Japan, Australia, Lord Howe Island and Rapa Iti. In 2008, a brown tang was observed near Fort Lauderdale, Florida, far outside its native range. Biology Zebrasoma scopas feeds mainly on filamentous algae. For this purpose it has specialised pharyngeal teeth. It is usually found on the exposed side of reefs and in coral-rich lagoons. The adults are gregarious and sometimes form schools but the juveniles are solitary and are often to be found swimming among corals. The brown tang is monogamous, though spawning has been observed both between pairs and among small groups. The male tends to be larger than the female. The fish rush up to the surface to spawn, fertilisation is external and the eggs are scattered in the water column. The larvae are planktonic for several weeks before settling and undergoing metamorphosis into juveniles. Use in aquaria Zebrasoma scopas is readily available and are easier tangs for the novice aquarist. Brown tangs do not bother coral and are safe to keep in a reef aquarium. They are smaller and less aggressive than other members of the family Acanthuridae. Brown tangs require an aquarium no less than 75 gallons. These fish are more tolerant of a wide range of living conditions. They will accept various food including meaty materials but the main part of the diet should be vegetable. They will eat the algae that tend to grow inadvertently in the tank. Brown tangs are one of the more peaceful species within its genus and can be kept with other species of tangs.
