Originally reported from the Malabon River, Rizal, Philippines, an area which has since been 'reclaimed'. It has supposedly also been collected in the sea at Culion Island, off Palawan, Philippines (see account on FishBase). Recently collected in Bali, Sulawesi and Singapore (M. Kottelat, pers. comm.). According to FishBase there are also supposedly records from Fiji and Papua New Guinea.

The species used to frequent shady river banks in the Malabon River, Rizal Province, Luzon, Philippines (the type locality), however, the area has been 'reclaimed' and the remaining waters in the area are heavily polluted; hence the species is considered extinct in the Philippines (R. Froese, pers. comm.).
