(Ostorhinchus cyanosoma)
Ostorhinchus cyanosoma, commonly known as the yellow-striped cardinalfish, goldenstriped cardinalfish, or the orange-lined cardinalfish, is a species of marine fish in the cardinalfish family (family Apogonidae) of order Perciformes. It is native to the Indo-West Pacific. O. cyanosoma is usually a blueish silver color with orange-yellow stripes, and grows to be an average of 6 centimeters. It lives in waters up to 50m in depth, often in lagoons or coral reefs. It is active during the nighttime, feeding on small plants and animals, mostly plankton. It has been the subject of research to test what might happen to marine life by the year 2100, due to predicted carbon dioxide levels in the atmosphere.
