[1] Loach minnow has an elongated, compressed body with its size rarely exceeding 65 mm (2.6 in) in length.

[citation needed] Loach minnows can be found at turbulent, rocky riffles of mainstream rivers.

Members of this species are opportunistic benthic insectivores: they seek food at the bottom substrate for riffle-dwelling larval ephemeropterans, simuliid, and chironomid dipterans.

[10] The critical habitat designation was subject to controversy and litigation, causing it to be rescinded, redesignated and altered.

[11] In 2012, the loach minnow was declared "endangered" alongside the spikedace (Meda fulgida),[4] with which it shares much of its range.
