Habitat and Ecology [top]
Habitat and Ecology: Found in fast-flowing stream with slightly tea-coloured waters draining from a freshwater swamp forest.

Systems: Freshwater
Threats [top]
Major Threat(s): The island of Batam (400 km²) is being rapidly developed and large tracts of land are currently being, or have already been, cleared for housing, industrial and commercial projects. The scale of the development plans are such that much of the native fauna will be (if not already) under serious threat in the years to come.
