Tampichthys
Tampichthys is a genus of freshwater ray-finned fish belonging to the family Leuciscidae, the shiners, daces and minnows. The fishes in this genus are endemic to east–central Mexico. They are entirely restricted to the Pánuco River basin, except T. ipni, which also occurs in some other Mexican rivers that drain into the Gulf of Mexico.
These are small fish, generally no more than long, and overall brownish-silvery with a distinct dark horizontal line from the head to the tail base.
