Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C -

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.8 cm TL male/unsexed; (Ref. 111297); max. published weight: 6.50 g (Ref. 111297)
soft rays: 8 - 9. Distinguished from all other species of the genus Batasio, except Batasio merianiensis in having an adult coloration consisting of a dark oblique predorsal bar and a dark spot on the sides of the body below the middle of the adipose-fin base. Differs from Batasio merianiensis by having length of adipose-fin base 30.0-33.3% SL (vs. 22.2) and eye diameter 18.2-23.5% SL (vs. 25.9) (Ref. 74340).
Occurs in rivers and streams with moderate to swift current and a predominantly rocky bottom; less often in slow-flowing streams with a muddy substrate. Hides among stones or submerged vegetation during the day and comes out at night to feed (Ref. 44354).
