Notes


Inhabits streams with medium to strong current over sandy or pebble substrate. Observed to form small groups as large as 20 individuals above the substrate and around large rocks. This sociability is unusual for the family, so several individuals should be kept together in aquaria.

Closely related to Nemacheilus ornatus. Both have translucent bodies with a black lateral stripe (depending upon mood). While N. binotatus has only two vertical hash marks above the pectoral fin, N. ornatus has 12-14 vertical hashes, regularly-spaced from gill to tail. All fins are clear and colorless.
