Algansea is a genus of ray-finned fish in the family Leuciscidae, distributed in the Lerma–Chapala–Grande de Santiago, Pátzcuaro, Armería, Ameca, Ayutla and Tuxpan basins in west-central Mexico (mostly Jalisco, but also surrounding states and the State of Mexico).[1][2][3][4] The genus includes both species that are locally numerous,[5] and species that are highly threatened.[2][4] Their closest relative is the longfin dace (Agosia chrysogaster).[3]

Algansea are fairly small fish that typically are between 5 and 15 cm (2–6 in) in standard length, although A. lacustris and A. popoche can reach up to 23–26 cm (9–10 in).[2][4] The different species are generally quite similar in their appearance, being yellowish- or olive-brown overall; darker on the upperparts and paler, more silvery on the underparts. They have a long blackish line along the side of the body from the gill covers to the tail base, or a blackish spot at the base of the tail.[2][4]
