The '''pearl danio''' ('''''Danio albolineatus''''') is a tropical, freshwater ray-finned fish belonging to the family Danioinidae.<ref name=Kullander2015>{{cite journal |author=Kullander, S.O. | year = 2015 | title = Taxonomy of chain ''Danio'', an Indo-Myanmar species assemblage, with descriptions of four new species (Teleostei: Cyprinidae) | journal = Ichthyological Exploration of Freshwaters | volume = 25 | issue = 4 | pages = 357–380 | url = http://www.pfeil-verlag.de/04biol/pdf/ief25_4_08.pdf }}</ref> Originating in Sumatra, Myanmar, and Thailand and Vietnam (Phu Quoc Island), this fish is sometimes found in aquariums by fish-keeping hobbyists. It grows to a maximum length of {{convert|2.6|in|cm}} and lives for around five years. The fish could have a brownish-yellow, pink, or a silver body and two light yellow/white or blue/red stripes. It has an iridescent look. The female fish has two pairs of barbels.<ref name=FB>{{FishBase | genus = Danio | species = albolineatus | month = April | year = 2015}}</ref>

In the wild, the pearl danio is found in along the surface of small, clear rivers and hill streams. They live in a tropical climate with water with a 6.0 – 8.0 pH, a water hardness of up to 5 – 19 dGH, and a temperature range of {{convert|68|–|77|F|C}}. Their diet consists mostly of exogenous insects and zooplankton. The pearl danio is an egglayer. Golden varieties are often seen in shops; these are in reality semi-albino fish.<ref>[http://www.danios.info/fish/albolineatus.aspx ''Danio abolineatus'']</ref> The '''blue-redstripe danio''' (''D. pulcher'') and the '''Kedah danio''' (''D. tweediei'') were considered synonymous with this species, but ''Eschmeyer's Catalog of Fishes'' recognises them as valid, distinct species.<ref name = "Cof genus">{{cof genus|genus=Danio|access-date-16 February 2025}}</ref>
