Life Cycle
provided by Fishbase
Aggression is used commonly in courtship. Spawning commences when after swimming together in different tufts, the female concentrates on just one and begins to thrust repeatedly and pause. The male follows suit nuzzling the female. The female then drops into the algae and spawns, while the male releases the sperm beside her. The pair then swims back to their territory (Ref. 46144). Monogamous mating is observed as both facultative and social (Ref. 52884).

Trophic Strategy
provided by Fishbase
Occurs in clear lagoon and seaward reefs from 0.5 to at least 30 m. Found in pairs or small groups and nests near bases of dead corals, often on clumps of algae. Monogamous (Ref. 52884, 48637). Feeds exclusively on Acropora polyps and is therefore restricted to areas of abundant coral growth. Feeding takes place throughout the day becoming less towards the evening (Ref. 46144). Pairs are commonly encountered among branching or "tabletop" corals (Ref. 54301). Tend to have protruding snout and teeth that project from small mouth which permit them to snip off scleractinian coral polyps despite the surrounding calcareous armor (Ref. 59308).

利用
provided by The Fish Database of Taiwan
小型魚類，常見但產量不多，無經濟價值。以其豔麗的體色而常被飼養於水族館中，供人欣賞，是極受歡迎之魚種。
描述

體長橢圓形；尾柄短而高，上有許多倒置的剛毛。吻較長且延長呈管狀。口上位。鰓孔約與瞳孔同大，位眼後下方體中線上，胸鰭基並未完全落於鰓孔下方。恥骨末端無特化之鱗片；體被小鱗，上有一列向後倒之平貼小棘。第I背鰭棘位眼後上方，棘強壯，前緣具成列指向上方之小棘，後緣小棘較鈍；背鰭條與臀鰭條前部不較後部長多少；鰭緣截平；腹鰭膜小。體藍綠色，具許多約為瞳孔一至二倍大之成列橘黃色圓形、卵圓形或長條形斑點；頭部斑點連成線狀；眼睛內、瞳孔外緣具與體之黃斑相接的放射狀黃帶。第一背鰭膜灰黃色；腹鰭膜黑色，雄魚散有小白點，幼魚則無；尾鰭淡藍綠色，後下方有一長黑斑；餘鰭淡黃而透明。
棲地
provided by The Fish Database of Taiwan
主要棲息於澄清的潟湖及面海的礁區，一般被發現於水深0-30公尺內的水域，成對或成小群生活於海藻叢或築巢於死珊瑚之基部。以珊瑚之水螅體為食。
Orange spotted filefish
provided by wikipedia EN
The orange spotted filefish or harlequin filefish, Oxymonacanthus longirostris, is a filefish in the family Monacanthidae found on coral reefs in the Indo-Pacific Oceans. The orangespotted filefish is a different species and refers to Cantherhines pullus.[1]
The orange spotted filefish is pale blue with about eight longitudinal rows of orange-yellow patches. In the wild it feeds almost exclusively on Acropora polyps.
[2]
In the aquarium
They are often offered for sale in the aquarium trade, but few survive long in captivity.[3] They are difficult to maintain in an aquarium unless provided with live corals. They must be kept in species-specific tanks, or tanks with very passive tankmates such as seahorses or pipefish. They have been successfully bred in captivity.[4]
In the wild
Harlequin Filefish, Vilamendhoo Maldives
Orange spotted filefish absorb and use chemicals in the Acropora coral they eat to take on its smell, which cloaks them from natural predators like cod. In addition to this trait, not observed among other vertebrates, they also use visual camouflage.[5]
