Comments: Originally reported from the Malabon River, Rizal, Philippines, which has meanwhile been reclaimed. First described by Herre in 1927 and was rediscovered in 1950 at Dagatdagatan Saltwater Fishery Experimental Station in Malabon (Ref. 4924). Reported in the sea at Culion Island, off Palawan (Ref. 6216). Also reported from Taal Lake (Ref. 12165). Endemism questionable since this species is also reported from other countries (Kottelat, pers. comm.). Also Ref. 439, 2060, 4924, 48613, 94476.

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 (Ref. 4924); further characterized by presence of black spot at middle of caudal fin base; first dorsal fin yellowish with black anterior; rounded caudal fin (Ref. 90102).

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.).
