This is one of the smallest freshwater fishes: males are mature at 9 mm, females at 15 mm. The species used to frequent shady river banks in the Malabon River, Rizal Province, Luzon, Philippines; however, the type locality has been reclaimed and the remaining waters in the area are heavily polluted; the species is considered extinct in the Philippines (Rainer Froese, pers. comm., 2004). It has been apparently imported into Germany in 1958; a color photo of the fish was taken in an aquarium (Ref. 2060). Found in brackish waters and mangrove areas of Indonesia (M. Kottelat, pers. comm.).
