Range and Identity
The original inventory identity Notropis braytoni is retained. The compiled range includes the Rio Grande from near its mouth toward the Rio Conchos confluence, the lower Pecos in Texas, and Rio Grande drainages in northern Mexico. A border does not divide the shared river ecosystem.
Habitat and Behavior
Adults inhabit rocky and sandy channels of large creeks and small to medium rivers. This channel setting should remain explicit rather than being generalized to every isolated pond or reservoir nearby. The actual tributary and bottom type provide useful locality context.
Food and Life History
The upper reference is 6.9 centimeters total length. Aquatic insects are the stated food. An independent maximum weight and a detailed migration or reproductive sequence are not established in the checked summary. The alternative genus name does not create a separate fish entry.
Field Note
Keep both scientific-name forms when comparing reports. They help connect older and newer references while preserving the exact name attached to the original observation.
