Danio pulcher, the blue-redstripe danio, is a species of freshwater ray-finned fish belonging to the family Danionidae. This species is found in Thailand. It was previously considered to be a synonym of D. albolineata the pearl danio but Eschmeyer's Catalog of Fishes recognises this as a valid species.
