Short description Khóa để định loại | Hình thái học | Sinh trắc học

Các tia vây lưng cứng (tổng cộng) : 15 - 17; Các vây lưng mềm (tổng cộng) : 6 - 8; Tia cứng vây hậu môn: 3; Tia mềm vây hậu môn: 6 - 7. Can be distinguished easily by its three longitudinal rows of dark grey to blackish, horizontally elongate, dash-like spots on the sides of the body; and caudal fin spatulate in adult males. Exhibits clear sexual size and color dimorphism (Ref. 85095).

Sinh học     Tự điển (thí dụ epibenthic)

Inhabits exclusively clear-water rivers. Juveniles measuring about 2.0 cm SL occur in small brooks with sandy bottoms and patches of leaf litter. Observed searching the bottom substrate for small invertebrates and detritus by picking up and turning the leaves. Collected only in very soft water (no detectable hardness) with high acidity, pH value mostly less than 4 (Ref. 85095).
