Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 1.0, range 1 - 1.1 cm
Max length : 1.1 cm SL 雄鱼/尚未辨别雌雄; (Ref. 2060); 1.5 cm TL (female)
背棘 (总数): 7; 背的软条 (总数): 6-7; 臀棘 1; 臀鳍软条: 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 (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).
在身体侧边上的深色的斑点略微形成 4个交叉的条纹; 在鳍的所有基底上的重的颜色, 除了腹面以外, 显然地是身体颜色的继续。 头部与后颈裸露的。 在纵向的系列中的 22 到 25个鳞片。
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.).
这是最小的淡水鱼之一: 雄性是在 9 mm 时成熟, 雌性在 15 mm。 此鱼种在 Malabon 河， Rizal 省中习惯于长年遮荫的河岸了, 菲律宾吕宋岛; 然而，模式标本产地已经被开垦，而且在区域的剩余的水域很重地被污染; 此鱼种一般认为灭绝的在菲律宾 (下雨 Froese ， pers. comm。, 2004)。 在 1958 年进入德国之内显然地它有被输入; 鱼的一张彩色相片在一个水族馆采集。 (参考文献 2060) 发现于半咸淡水域与印度尼西亚的红树林区域 (M. Kottelat， pers. comm.)。
