Diagnostic Description
provided by Fishbase
This species is distinguished by the following characters: head scales reaching to or just in front of anterior nostrils; lateral line scales 43-47 (usually 45-46); pectoral fin rays 16-18 (usually 17); snout length less than eye diameter; greatest body depth 2.5-3.0 in SL. Colour dark grey on head and back with diagonal black-edged white band separating dark area from the rest of the mainly whitish body; white blotch below posterior dorsal fin; 3 yellow stripes on upper head; juveniles with alternating black and yellow stripes on the upper half and whitish below, Batesian mimic of the poison-fanged blenny Meiacanthus grammistes (Ref. 90102).
Morphology
provided by Fishbase
Dorsal spines (total): 10; Dorsal soft rays (total): 9; Analspines: 3; Analsoft rays: 7
Trophic Strategy
provided by Fishbase
Occur inshore (Ref. 75154). Found in small aggregations. Juveniles appear to be Batesian mimics of poison-fanged blenniids (Meiacanthus).
Biology
provided by Fishbase
Common on coral reefs. Adults occur on most reef habitats, usually in pairs, and juveniles inshore or in lagoons or rubble zones (Ref. 48635). Occurs singly or in small aggregations. Feeds on small fishes and benthic invertebrates. A protogynous hermaphrodite (Ref. 9785). Juvenile mimics poison-danged blenny Miacanthus grammistes, Batesian mimic (Ref. 90102). Caught mainly by handline and live specimens captured by hand net for the aquarium export trade; no major fishery exists (Ref. 9785). It is parasitised by the monogenean Anoplodiscus hutsonae on the pectoral fins and body surface (Ref. 124057).

分布於印度-西太平洋區，西起印尼，東至萬那杜，北至日本南部，南至澳洲及新加勒多尼亞皆有分布。台灣各海域皆可發現。
利用
provided by The Fish Database of Taiwan
本魚全年皆有產，可利用手釣或在礁岩外砂地放流刺網捕獲，唯因其多單獨活動，故捕獲數量通常不多。體色豔麗，常被飼養於水族箱內。

Two-lined monocle bream

The two-lined monocle bream (Scolopsis bilineata) is a species of threadfin bream native to the Indian Ocean and the western Pacific Ocean. An inhabitant of coral reefs, this species can be found at depths from 1 to 25 m (3.3 to 82.0 ft). They are carnivorous, preying on smaller fishes, as well as benthic invertebrates. This species can reach a length of 25 cm (9.8 in), though most only reach a length of around 13 cm (5.1 in). This species is sought-after by local peoples for food and can also be found in the aquarium trade.[1]
The two-lined monocle bream exhibits biofluorescence, that is, when illuminated by blue or ultraviolet light, it re-emits it as green, and appears differently than under white light illumination (only stripes on the upper front part are visible). Biofluorescence may assist in intraspecific communication and camouflage, blending the fish with green-fluorescing Acropora corals.[2]
