Datnioides microlepis, also known as the Indonesian tiger perch, Indo datmoid, Indonesian tigerfish, or finescale tigerfish, is a species of freshwater ray-finned fish belonging to the family Lobotidae, the tripletails and tiger perches.

[2] Datnioides microlepis was first formally described in 1854 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker with its type locality given as the Kapuas River at Pontianak, Kalimantan, Indonesia.

[8][9] It may be identified from its congeners by having 6 or 7 broad dark vertical bars on the body, with a yellowish-grey background colour.

[10] Datnioides microlepis is found in Sumatra and western Kalimantan on Borneo in large lowland rivers, sometimes entering brackish waters.

[8] Records of this species from the drainage basins of the Chao Praya and Mekong are thought to refer to the Siamese tigerfish.
