Danionella translucida is an extremely small (1.1 cm long) species of cyprinid fish endemic to Myanmar.

It was collected from the roots of floating aquatic plants in a slow-flowing, shallow stream (maximum depth 1 m) in the Pegu Division of Myanmar.

It was found alongside Danio, Microrasbora, Erethistes, and Oryzias species.

There are no melanophores on the dorsal surface except on the head over the posterior part of the brain.

A double row of melanophores is present on the underside of the fish from the isthmus of the gills to the pelvic fins.
