Chapalichthys is a genus of splitfins that are endemic to west-central Mexico, where found in lakes, pools, ponds and channels in the Lerma–Chapala–Grande de Santiago and Balsas basins.
[2][3] Chapalichthys reach up to 9.3 cm (3.7 in) in standard length.
Despite this relatively small size, they are often caught as food in Lake Chapala.
[2] There are currently three species in this genus according to FishBase,[4] but some authorities only recognize two, treating C. peraticus as a junior synonym of C.
