Alchichica silverside
The Alchichica silverside ("Poblana alchichica") is a species of neotropical silverside endemic to Lake Alchichica in Mexico.
"Poblana achichica" measures up to 10 in. (25 cm). According to a 2001 book, information on its breeding habits are not widely known and its primary food source is small aquatic invertebrates. The threats to "Poblana achichica" are largemouth bass and the habitat destruction from people.
This species was described by Don Fernando de Buen y Lozano in 1945 from a
Chignahuapan silverside "(P. ferdebueni)", and Quechulac silverside "(P. squamata)". Three species of dace "(Evarra bustamantei, E. eigenmanni," and "E. tlahuacensis)" formerly native to the basin are presumed extinct since about 1970.
The WWF-Nature Conservancy system of freshwater ecoregions includes the Oriental Basin with the Valley of Mexico, Lerma River, and Lake Chapala in their Lerma-Chapala freshwater ecoregion, based on faunal similarities, especially among the Atherinopsids.
