海洋 礁区鱼类; 深度上下限 10 - 36 m (Ref. 1602). 热带; 30°N - 24°S
Central Pacific, including Hawaiian Islands. Indian Ocean species were re-identified as Canthigaster petersii (Ref. 123151).
Population from the Philippines, Indonesia, New Guinea, Queensland, and Belau differs in coloration (formerly Canthigaster papua);
Replaced by Canthigaster margaritata in the Red Sea.
印度-太平洋: 东非到列岛群岛与 Tuamoto 岛, 北至琉球群岛, 南至新加勒多尼亚与东加; 迷途的鱼到夏威夷群岛。 族群从菲律宾，印度尼西亚，新几内亚，昆士兰省与帛琉不同之处为颜色;(从前 Canthigaster papua) 在红海被 珍珠扁背鲀〔Canthigaster margaritata〕 取代了。

Inhabit sheltered rocky reefs (Ref. 48637). Also live in intertidal reef flats, lagoon and seaward reefs. Occur over open barren areas, also among corals and under ledges (Ref. 9710). Benthopelagic (Ref. 58302). Often found in pairs, sometimes in small groups. Feed mainly on filamentous red and green algae and coralline red algae but also on corals, tunicates, mollusks, echinoderms, polychaetes, crustaceans and bryozoans. Common (Ref. 9710). Monogamous (Ref. 52884).
栖息于掩蔽的岩礁。 (参考文献 48637) 也生活在潮间带的礁石平台，舄湖与临海礁石中。 生活在开放的贫瘠区域之上, 也在珊瑚与岩架下之中。 经常成对出现, 有时形成小群鱼群。 主要吃丝状的红藻与绿藻，而且珊瑚的红藻也捕食珊瑚，被囊类，软件动物，棘皮动物，多毛类动物，甲壳动物与苔藓虫类。 普遍的.(参考文献 9710) 一夫一妻的.(参考文献 52884)

Oviparous (Ref. 205). Displays facultative monogamy where males are constrained to mate with a single female due to resource limitation (Ref. 52884).印度-太平洋: 东非到列岛群岛与 Tuamoto 岛, 北至琉球群岛, 南至新加勒多尼亚与东加; 迷途的鱼到夏威夷群岛。 族群从菲律宾，印度尼西亚，新几内亚，昆士兰省与帛琉不同之处为颜色;(从前 Canthigaster papua) 在红海被 珍珠扁背鲀〔Canthigaster margaritata〕 取代了。
