This attractive species mainly inhabits acidic forest streams, but can also survive in more neutral open-country streams. It searches the stream bed for its foodstuff - insects, worms and crustacean larvae, and at other times is pelagic i.e. free-swimming in midwater.

As with many other Rasboras the scales are yellow-gold, however in this species there is a purple tinge towards the posterior. The distinguishing feature is the thin, dark lateral band.

Einthoven's Rasbora ranges from Thailand through Peninsular Malaysia and Singapore to parts of Indonesia including the Riau Archipelago and Borneo.
