背棘 (總數) : 7; 背的軟條 (總數) : 6 - 7; 臀棘: 1; 臀鰭軟條: 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.

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.).
這是最小的淡水魚之一: 雄性是在 9 mm 時成熟, 雌性在 15 mm。 此魚種在 Malabon 河， Rizal 省中習慣於長年遮蔭的河岸了, 菲律賓呂宋島; 然而，模式標本產地已經被開墾與在區域中剩餘的水域是嚴重污染; 此魚種一般認為滅絕的在菲律賓 (下雨 Froese ， pers. comm。,2004)。 在 1958 年進入德國之內顯然地它有被輸入; 魚的一張彩色相片在一個水族館採集。 (參考文獻 2060) 發現於半鹹淡水域與印尼的紅樹林區域 (M. Kottelat ， pers. comm.)。
