Relevant Information:

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal soft rays: 12. Greyish brown body with a dark brown predorsal oblique bar and a dark brown spot on the side of the body below the adipose fin, dark brown band on distal half of dorsal fin. Dorsal-spine length 14.0% SL; body depth at anus 18.0% SL; snout length 36.0% HL; eye diameter 24.4% HL; interorbital distance 31.7% HL. Batasio species generally are found in fast-flowing hillstreams. Southeast Asian Batasio will tolerate slightly warmer waters than their Indian counterparts. It appears that all Batasio need a lot of current and a high oxygen content.
