簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 14 - 15; 背的軟條 (總數): 9-10; 臀棘 3; 臀鰭軟條: 8. Distinguished from all its congeners by the combination of the following characters: usually with 15 spines and 10 rays on dorsal fin; 23-25 scales in E1 row; dorsal fin base only moderately scaly; absence of conspicuous pattern of cross series of tiny light dots; and maximum length of 7.4 cm SL (Ref. 58749).
與它所有的同類區分了藉由下列特徵的組合: 在背鰭上通常有 15根棘與 10個鰭條; 在 E1 列的 23-25個鱗片; 背鰭基底只有一般有鱗; 缺乏交叉成列的極小淡點的顯著圖案; 而且 7.4 公分 SL 的最大長度.(參考文獻 58749)
Prefers typical blackwater habitats with clear, acid and very soft-tea colored water. Usually found along the banks of brooks and small rivulets in areas of extremely shallow water with water depth approximately between 10 and 50 cm, where they occur either in a layer of dead leaves covering the bottom of the bank side or among submerged terrestrial vegetation (Ref. 58749).
偏愛典型的死水棲息地有清澈的, 酸與非常軟-茶色彩水。 通常發現於在 10 與 50 公分之間和水深度大約沿著在非常地淺水區的區域中的小溪淺堆與小的小河, 在那裡它們出現或在淺堆側邊的枯葉覆蓋底部的層中或在水下的陸棲植物之中.(參考文獻 58749)
