Identification
The dark side stripe passes through the eye toward the snout but does not extend onto the lower lip. Small dark marks above and below lateral-line pores form paired rows of dashes. Dark scale pockets give the upper body a crosshatched appearance.
Range and Habitat
The Devils River and San Felipe Creek are among its documented Texas habitats, with additional regional streams and northern Mexican records. It is not a mainstem Rio Grande fish. Clean, flowing water influenced by springs and gravelly substrate form important habitat components.
Food and Reproduction
The natural diet includes algae and detritus. Females can release several batches of eggs during an extended winter-to-summer reproductive period. Spawning observations include association with nest sites made by other fishes, linking reproduction with the structure of the stream community.
Do Not Substitute Aquarium Food
A captive feeding recipe is not the wild diet. Algae and detritus are the documented natural foods relevant to this minnow’s stream ecology.
