[4] Possibly used to be wildly spread across Peninsular Malaysia before, now only found in Johor, the North Selangor peat swamp forest, Selangor state and Perak.

Its now smaller range is probably due to the degradation of peat swamps across Peninsular Malaysia.

Specimens have also been collected from the Kapuas River basin, and in West Kalimantan of Indonesian Borneo.

[3] Most often found in black water habitats with lots of vegetation such as blackwater streams or pools,[3] and often caught in congregations around areas of streams where there is more current, possibly attracted to the more oxygenated water.

[4] In the wild it can be seen grazing on biofilm, but it is also a micropredator that preys on small crustaceans, insect larvae and other aquatic invertebrates.
