It inhabits shallow streams with a rocky bottom. The diet consists of insects such as simulids and chironomids.[3] DescriptionBalsas shiner have an elongated body and can grow to {{convert|12|cm|abbr=on}} total length. The mouth is sub-terminal. The body is silver in color, slightly darker dorsally, and with a black stripe that runs from the eye to the caudal fin. During the reproductive season that peaks in the winter, the ventral region develops bright red coloration.[3] ConservationBalsas shiner is considered threatened in Mexico, but its narrow range should qualify it as critically endangered.[3] It has not been assessed by the International Union for Conservation of Nature (IUCN).[2] References1. ^{{cite web |url=http://researcharchive.calacademy.org/research/ichthyology/catalog/fishcatget.asp?spid=30551 |title=Catalog of Fishes |author=Eschmeyer, W.
