Rio Grande Cichlids are native to the lower Rio Grande drainage basin, from northeastern Mexico into the state of Texas. They have been introduced into the states of Arizona, Florida, Illinois, Louisiana, Nebraska, Nevada, and Ohio, as well as Puerto Rico. They can be found in flowing waters such as riffles in ponds, lagoons, creeks, rivers, and springs. Rio Grande Cichlids are olive green in colour, occasionally with darker vertical bars that are more prominent toward the tail, and are speckled with distinct cream to turquoise spots. They can reach nearly 12 inches (30 cm) in length, though they are more commonly found in the 4–5 inch (10–13 cm) range. Due to their striking coloration, they are popular as ornamental fish, but are also caught as sport fish and are considered good eating. They are omnivorous, feeding on small fish, fish eggs, aquatic invertebrates, and plant matter.
