Maturity: Lm ?  range ? - ? cm
Max length : 16.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 6705)
Tends to form small shoals. More abundant in the larger, clear water, undisturbed, deep (>1m), heavily shaded streams. Stays in the middle of the water column (Ref. 6468). Feeds on filamentous algae, terrestrial insects and detritus (Ref. 6703). No observations on breeding in captivity. Maturity at 6.4 cm (Ref. 6468). Does well at 29°C water temperature. Exploited by the tropical fish export trade, larger specimens are eaten.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00516 - 0.02330), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
