Juan Miguel Artigas Azas takes a look at the feisty Cichlasoma istlanum. Originally described in the genus Heros, the fish was reclassified by Tate Regan in the Cichlasoma section Patapetenia in 1905 (Regan, 1905). Cichlasoma istlanum has one of the largest geographical distribution areas of all Central American cichlids. It is however, the only natural cichlid species found in its range. Its distribution extends from N lat 20 in the north, in the Rio Armeria and Coahuayana basins in the pacific slope of Mexico (west of the country), to the South in Rfo Papagayo (south of the country). Cichiasoma istlanum can be found in rivers and lakes not over 1,000m above sea level.
