 In Louisiana, the fish has slowly taken over the waters of New Orleans.The fish has a high salinity tolerance (up to 8ppt), but it is likely that this is caused by the interbreeding of this fish and the "Herichthys carpintis", which makes it an ideal invader for the brackish conditions of southern Louisiana.It is believed that this fish has entered into the New Orleans area through multiple aquarium releases in central Jefferson Parish in 1989.
