The Texas cichli (Herichthys cyanoguttatus, formerly Cichlasoma cyanoguttatum) is a freshwater fish of the cichlid family. Also known as Rio Grande cichlid, this species is originated from the lower Rio Grande drainage in Texas and Northeastern Mexico, particular on the sandy bottom of deep rivers. This is the only cichlid species native to the United States, and has been introduced by man as far North as Central Texas where they live in various lakes and rivers.
