The red-eye wrasse (Cirrhilabrus solorensis) is a species of wrasse native to Indonesia and Australia, where found near the Lesser Sundas, Maluka and Darwin. It inhabits coral reefs on coastal and outer reef lagoons at depths of 5 to 35 m (16 to 115 ft).
Adult male C. solorensis have a yellowish-dusky or yellow-green snout to crown, blue operculum, purple neck-region, yellow-orange upper body and blue belly. It can reach a total length of 11 cm (4.3 in).Until 2021, it was commonly confused with C. aquamarinus and C. chaliasi, which occur in similar habitats and all have mostly reddish eyes. In C. aquamarinus, which is found near Sulawesi, the adult male has a mostly deep yellow head, a dark blue back and operculum, and much of the body is blue-green. In C. chaliasi, which is found near the Lesser Sundas and Tukangbesi Islands, the adult male has a pinkish-red head, yellow-orange upper body and blue belly.Females of these species are considerably duller and not as easily separated.

The foxface rabbitfish (Siganus vulpinus), also known as the foxface, black-face rabbit fish, badger fish or the common foxface is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is found in the Indian and Pacific Oceans. It can be found in the aquarium trade.
Taxonomy
The foxface rabbitfish was first formally described as Amphacanthus vulpinus in 1845 by the German zoologists Hermann Schlegel & Salomon Müller with the type locality given as Ternate Island one of the Molucca Islands in Indonesia.The blotched foxface (S. unimaculatus) differs from S. vulpinus in possessing a large black spot below the soft-rayed part of the dorsal fin. It is sympatric and not phylogenetically distinct, and though these two might be recently evolved species, they may be just colour morphs and should arguably to be united under the scientific name S. vulpinus. under the scientific name S. vulpinus.The specific name vulpinus means "fox-like", Schlegel and Müller did not explain what this alluded to but it is thought to be the pointed snout.
Description
The foxface rabbitfish has a compressed body which has a depth which fits into its standard length 1.9 to 2.4 times. The dorsal profile of the head is steep to the rear of the eye and there is an indentation between the eyes and a tubular snout. The caudal fin is weakly forked. There is a procumbent spine in the nape to the front of the dorsal fin.Like all rabbitfishes, the dorsal fin has 13 spines and 10 soft rays while the anal fin has 7 spines and 9 soft rays. The fin spines hold venom glands. This species attains a maximum total length of 25 cm (9.8 in), although 20 cm (7.9 in) is more typical.The main colour on this rabbitfish is vivid yellow with white on the head and front part of the body, however foxfaces can camouflage when experiencing threat, quickly changing colour to a dark brown. There is a black band running backwards from the mouth through the eye to the start of the dorsal fin and there is a black area on the breast that runs upwards to just above the base of the pectoral-fin, tapering as it does so.
Distribution and habitat
The foxface rabbitfish occurs in the far eastern Indian Ocean and in the western Pacific from Indonesia to the Marshall and Gilbert Islands north as far as Taiwan and south to New Caledonia and Australia.[1] In Australia it is found from Western Australia on the northern reefs and offshore reefs, at Ashmore Reef in the Timor Sea, and on the east coast in Queensland from the northern Great Barrier Reef to the Capricorn Islands. It has been recorded as deep as 30 m (98 ft).[1] This species lives in lagoons and seaward reefs where there is a rich growth of corals.
Biology
The foxface rabbitfish is omnivorous, eating mostly algae and zooplankton. They may be territorial, adults are normally found as either solitary individuals or in pairs and are associated with branching Acropora corals. Juveniles and subadults may sometimes form large schools, feeding on algae growing on the bases of Acropora corals.This species produces venom in the spines of its fins.In a study of the venom of a congener it was found that rabbitfish venom was similar to the venom of stonefishes.
Utilisation
The foxface rabbitfish appears in the aquarium trade. No statistics are kept for the catch and in some areas this species appears in mixed catches of reef fish, caught by spearfishing.
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.
