Herichthys ( Heros + gr .: "Ichthys"), German pearl cichlids , is agenus of cichlids (Cichlidae)occurringin northeast Mexico and southern Texas (river basin of the Rio Grande ).

features

The species of the genus Herichthys are 12 to 30 cm long and have a relatively high-backed, oval and laterally flattened body and a relatively large head with a terminal mouth. The diagnostic feature of the genus given in the first description is the tooth shape of the front row of teeth. They are described as simple, with no side hooks. Most of the Herichthys species show a dark longitudinal band on the sides of the body broken up into irregular spots and a more or less distinct dark spot on the tail stalk. Part of the dorsal fin is often dark, especially in females. During brood care, these show a striking contrasting coloration with a dark belly and light sides of the body.

species

There are currently seven species of the Herichthys genus :

Seven other species of cichlids that were previously assigned to Herichthys are now included in the genus Nosferatu . It differs from Herichthys in the elongated pair of teeth on the jaw symphysis .
