The Texas Cichlid (Herichthys Cyanoguttatus) is the only cichlid native to the United States. It is also known as the Rio Grande Cichlid. This species came from the lower Rio Grande drainage in Texas and northeastern Mexico, particularly on the sandy bottom of deep rivers.
The Texas Cichlid has a large, grayish, high-backed body with bright blue scales and two dark spots, on at the center of the body and the other at the end of its tail. Adult males have a large hump on their head. The Texas Cichlid can grow to be 30 cm long.
This species is a prolific breeder and breeding them in an aquarium is very easy. Adult fish will pair up and become territorial. Up to 1,000 adhesive eggs are laid on a clean, flat surface and both parents guard them aggressively.
