Plains topminnows suffers from severe habitat fragmentation, which causes a lot of diversity among this species. This makes gene flow impossible, and causes a large amount of genetic variation. A sample of this species showed a 61% variation among males and 83% variation among females. This variation has caused the species to be discovered several different times within a short period of time by accident. Despite the severe differences, this species lacks a subspecies designation due to extreme genetic homogeneity within and between populations, possibly a result of the bottleneck effect.
