Juveniles (4-7 cm SL) at depths 1-5 m in quieter waters of outer reef flats, about coral patches of Acropora. They may occur in large numbers & may form loose feeding schools with similar-sized S. corallinus, S. doliatus, S. spinus, & scarids. Pair bond formation at about 7 cm SL; with increasing size, pairs venture onto where currents & wave action are stronger. Pairs of large adults live in open water on faces of drop-offs of coral reefs at depths 3-10 m.

Occurs in shallow, coral-rich areas of clear lagoons and seaward reefs. Individuals up to 7 cm SL forms large schools in shallows, lagoons and outer reef flats, particularly in areas dominated by luxurious growths of Acropora. Adults occur in pairs. Juveniles feed on filamentous algae, adults on algae, tunicates, and sponges (Ref. 9813, 48637). Can inflict painful stings (Ref. 4690).

主要棲息於水質清澈的潟湖或面海珊瑚礁區之淺水域。常成群活動。雜食性，以藻類及小型附著性無脊椎動物為食。白天在水層中覓食，夜間則至底層休息。各鰭鰭棘尖銳且具毒腺，刺到使人感到劇痛。
Masked spinefoot

fornì da wikipedia EN
The masked spinefoot (Siganus puellus), also known as the masked rabbitfish, bluelined rabbitfish, blue-lined spinefoot, decorated rabbitfish or maiden spinefoot, is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It occurs in shallow, coral-rich areas of clear lagoons and seaward reefs of the Indo-West Pacific region.
Taxonomy
The masked spinefoot was first formally described in 1852 as Ampacanthus puellus by the German zoologist Hermann Schlegel with the type locality given as Ternate in the Molucca Islands in Indonesia.[3] The specific name puellus means "a small boy". Schlegel did not explain why he chose that name.[4]
Description
The masked spinefoot has a compressed body. The depth of its body fits between 2.3 and 2.6 times into its standard length. It has a symmetrical wedge-shaped head with a slightly protruding snout. The front nostril is flanged, the flange growing in to a triangle shaped flap to the rear. There is a recumbent spine to the front of the dorsal fin.[5] Like all rabbitfishes, the dorsal fin has 13 spines and 10 soft rays while the anal fin has 7 spines and 9 soft rays.[2] The fin spines are robust and hold venom glands.[6] The caudal fin is strongly forked, especially in adults, with acutely pointed lobes.[5] This species attains a maximum total length of 38 cm (15 in), although 25 cm (9.8 in) is more typical.[2] The upper body is yellow shading to light blue to white on the lower body. It is marked with sinuous blue lines that are vertical towards the head and horizontal towards the tail. These are replaced with blue spots towards the abdomen. There is a broad diagonal black band that runs through the eye and extends from the chin to the nape. Over the eye, this band breaks up into black spots. The colour of the fins is yellow.[7]
Distribution and habitat
The masked spinefoot has a wide Indo-West Pacific range which extends from the Cocos-Keeling Islands and the outer reefs of northwestern Shelf of Western Australia through Indonesia to the Ryukyu Islands and Kiribati, to southern Great Barrier Reef and New Caledonia. It is found to depths down to 30 m (98 ft)[1] in the shallow waters of clear lagoon rich in corals and on seaward reefs.[2]
Biology
Masked spinefoot juveniles school, especially over areas dominated by Acropora branching corals.[6] The adults live in pairs on the reef, pairing starting at lengths around 7 cm (2.8 in) when they move into deeper water on the reef and near drop offs. The juveniles feed on filamentous algae while the adults feeds on macroalgae and on sponges of the order Monaxonida.[1] This species produces venom in the spines of its fins.[2] In a study of the venom of a congener it was found that rabbitfish venom was similar to the venom of stonefishes.[8]
Hunting
The masked spinefoot is caught by spearfishing and in fish traps and small amounts are regularly found in fish markets.[5] It makes occasional appearances in the aquarium trade.[9]
