Info
Labracoglossa nitida is a slender perch with a bright blue streak that becomes paler below, and a broad yellow stripe along the dorsum, caudal peduncle, and tail.
The yellow caudal and anal fins show a fine blue stripe that blends into the yellow stripe along the lateral line, and a black spot at the base of the pectoral fin.
Blue knifefish have low dorsal and anal fins and a deeply forked tail.
The yellow-blue coloration and elongated body profile resemble fusiliers.
Labracoglossa nitida forms pelagic schools, usually in surface waters off landings, around rocks and around offshore islands.
The blue knifefish differs from Labracoglossa argenteiventris in having smaller scales and ten dorsal spines instead of eleven.
The species name is derived from the Latin "nitida" (= bright, shiny, glossy), possibly in reference to the light blue color of this species.
