Short description

Dorsal spines (total): 7; Dorsal soft rays (total): 6 - 7; Anal spines: 1; Anal soft rays: 6 - 7. Dark spots on sides of body somewhat forming 4 cross-bands; heavy pigmentations on all bases of fins, except ventrals, apparently are continuation of body pigmentation. Head and nape naked. 22 to 25 scales in longitudinal series.

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.).
