Tristramella simonis, the short jaw tristramella, is a vulnerable species of cichlid fish from the Jordan River system, including Lake Tiberias (Kinneret), in Israel and Syria, with introduced populations in the Nahr al-Kabir and Orontes basins in Syria.[1][2] It prefers waters with little or no movement.[2] Along with other tilapias, T. simonis is commonly caught as a food fish in parts of its range and it is commercially important in Lake Tiberias.[1][3]
