The pearl danio (Danio albolineatus) is a tropical, freshwater ray-finned fish belonging to the family Danioinidae.[2] 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 2.6 inches (6.5 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.[3]
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 68–77 °F (20–25 °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.[4] 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.[5]
