who is the rio grande cichlid
Cichlid of the family Cichlidae reaching 30 cm. Originally it lives in the lower Rio Grande basin, called Río Bravo in Mexico, in Texas and northeastern Mexico. It was introduced elsewhere, such as the Edwards Plateau in Texas and the Florida peninsula in the United States, as well as the Río Verde basin in the Media Luna region of Mexico, and Puerto Rico. It lives in pools and rapids of rivers of all sizes, in warm, vegetated water. It eats worms, crustaceans, insects and plant matter. Both parents care for the spawn.
