The ones in Ecajoe's picture are Indo dats, Datnioides microlepis. Some have four body bars, indicative of microlepis from Borneo. Indos from Sumatra typically have three body bars, similar to widebars but the configuration of the bars is different. If there is perceptible width at the bottom of the middle bar, it's an Indo. The middle bar on widebars (D. pulcher) comes to a point at or before reaching the ventral surface. Also, Indos typically have three tail stripes, whereas widebars can have two or three tail stripes. (Thus, the tail stripe ID is not always dispositive.)
Soulfish's dat is a thinbar dat, Datnioides undecimradiatus.
