Teuchitlán

The butterfly goodeid, Ameca splendens, is a livebearer from the Río Ameca drainage in Jalisco, Mexico, and the neighbouring Sayula valley. Often referred to as extinct in the wild, it still survives at a few localities, and strong captive populations exist in the hobby. As in other goodeids, the developing young are nourished by a structure known as the trophotaenia. Males can be quite aggressive, and it is better kept in a species set-up.
