Yellowstriped Cardinalfish Video Stock Footage

Large examples of Ostorhinchus cyanosoma grow to 8 cm in length although its average length is 6 cm. The fish is colored silver with a blueish tinge, and has six orange-yellow stripes including a short stripe behind the eye. A new species (Ostorhinchus rubrimacula) was separated out in 1998 from the O. cyanosoma species complex, with almost identical morphology but with a pinkish-red spot on the tail base, and the genetics were confirmed in 2014. Notably, whilst Bleeker noted red fins ('pinnis rubris') in his original sample, he never noted a red tail spot.
